''CNN'' reported April 7 the government only to "consider" to enlarge the evacuation zone and chief Secretary Edano to add there wouldn't be a timetable for making this decision yet<ref name="cnn_widen">http://edition.cnn.com/2011/WORLD/asiapcf/04/07/japan.nuclear.reactors/ as at April 8, 2011</ref>. A new safety category for long-term exposure would be in discussion to protect citizens against the impacts of accumulated radiation doses<ref name="cnn_widen" />. This would effectively extend the evacuation zone, a government's official said April 7<ref name="cnn_widen" />. The neighbourhoods by the Fukushima NPP will have to remain empty "for the long term", chief Secretary Edano said April 1<ref name="aljazeera_nosafelevels" />. Eventually on April 11 the evacuation zone was expanded to 30 km due to the discussed health risk of long-term radiation exposure including the following areas: Katsurao Village, Namie Town, Iitate Village and some parts of Kawamata Town and Minami Soma City<ref name="nhk_april_11"/>. Other areas in the 30 km zone will be evacuated at the latest after one month, while residents within this radius are told to be prepared for emergency evacuation, Chief Cabinet Secretary Edano said<ref name="nhk_april_11">http://www3.nhk.or.jp/daily/english/11_29.html as at April 11, 2011</ref>. In contradiction to a ruling by Japan's government imposing a no-entry zone prohibiting residents from remaining within a 20-kilometer radius of the Fukushima Daiichi nuclear power plant beginning as of 21th April<ref name="kyodonews_20110422" >http://english.kyodonews.jp/news/2011/04/86966.html as at April 22, 2011</ref>, the authorities permitted residents of the Kawauchi village inside the 20 kilometer zone to return to their homes for a limited time of some hours to take personal possessions out of the prohibited area, ''RT Moscow'' reported May 10<ref name="rtmoscow_return">http://rt.com/news/return-fukushima-zone-plant/ as at May 10, 2011</ref>.
+
 
+
On March 24, 23 members of Japan’s Parliament signed a statement urging a larger evacuation zone <ref name="nirs" />, while on March 28 some 168 citizens organizations in Japan submitted a petition to the government to enlarge the evacuation area<ref name="aljazeera_nosafelevels" />. The United States suggested the evacution zone to be enlarged up to 80 kilometers, and recommended US citizens not to stay there<ref name="aljazeera_nosafelevels" />.

=== Fukushima NPP To Be Scrapped - Compensation Claims On TEPCO ===
+
''TEPCO'' announced to scrap the four exploded ''Daiichi'' reactors, while chief Secretary Edano recommended to decommission all six units of the nuclear power plant<ref name="welt_shimizu" /><ref name="aljazeera_nosafelevels" />. The newspaper ''Mainichi'' reported the government's plan to give ''TEPCO'' an injection of money acquiring up to 50 % shares of the company<ref name="spiegel_schlampt">http://www.spiegel.de/panorama/0,1518,754404,00.html as at April 5, 2011</ref>. Fukushima's operator's stock exchange index had been fallen by 80 % within some three weeks since the beginning of the atomic disaster<ref name="spiegel_schlampt" /><ref name="worldwatch_statusreport" />. ''TEPCO'' will possibly be asked for tens of billions of dollars compensation due to the catastrophe<ref name="spiegel_schlampt" /><ref name="latimes_success" /> - the biggest size of claims in Japan's history<ref name="reuters_claims">http://www.reuters.com/article/2011/04/04/japan-tepco-liability-idUSL3E7F438W20110404 as at April 7, 2011</ref>. <span style="color:green">Latest calculations by analysts on behalf of the Worldwatch Institute estimated costs of $ 100 billions or more<ref name="worldwatch_statusreport">http://download.www.arte.tv/permanent/u1/tchernobyl/report2011.pdf as at June 1, 2011</ref>.</span> April 6 the ''Los Angeles Times'' reported ''TEPCO'' to have announced the day before to give "condolence payments" totaling about $2,000,000 to those residents who had to leave their homes due to the evacuation in connection with the atomic catastrophe at Fukushima<ref name="latimes_success" />.

+
=== New Threats To The Wrecked Reactors ===
+
Tons of water pumped into the reactors to cool the nuclear fuel could cause a collapse or serious damage of the containment structures especially in case of aftershocks as the March 11 earthquake could have compromised the stability of them, US experts in connection to a April 5 uncovered confidential paper of the US nuclear safety authority<ref name="nytimes_array" />. Partly workers had put hundreds of tons of water a day into the reactors<ref name="cnn_tsunami" />.
+
 
+
In a statement of April 1, 16 Japanese experts on nuclear power engineering, nuclear physics and radiology, said they could not rule out the possibility that a molten core melts a weak part of a pressure vessel and enters a containment vessel. Another possible threat they phrased was another hydrogen explosion destroying a containment vessel, causing a severe radioactive contamination of land and sea. That release could make uninhabitable larger areas than just the current evacuation zone. The current activities to cool the reactors 1-3 would not be capable to completely cool down the molten nuclear fuel to prevent it to burst through the bottom of pressure vessels.<ref name="japantimes_overcoming" />
+
 
+
=== Governmental Reactions To The Disaster ===
+
In response to the catastrophe Japan's government issued tougher regulations for emergency power at nuclear power plants including the requirement to provide two instead of just one diesel generators as backup for each reactor unit<ref name="cnn_tsunami" />.
+
 
+
=== Damages of the containment ===
+
On Saturday March 12 the Japanese authorities claimed the reactor pressure vessel of unit 1 of the ''Daiichi'' NPP wouldn't have been damaged. But this is in conflict with the officially confirmed releases of cesium. The evening before the first explosion the authorities already had claimed there would not be any danger of radioactivity releases. On the contrary, first independent meassurements of radiation showed a serious radioactivity even in a certain distance to the crashed reactor units<ref>https://www.facebook.com/notes/anti-nuclear/disaster-fukushima-the-first-independent-measurements-of-radioactivity-are-alarm/10150122538293442 as at March 14, 2011</ref>.
+
 
+
A suspected breach in the core at one reactor at a stricken Fukushima nuclear plant could mean more serious radioactive contamination, Japanese officials revealed Friday - a situation the prime minister called "very grave and serious", ''Assiocated Press'' reported on March 25<ref>http://www.chicagotribune.com/news/daywatch/sns-ap-as-japan-earthquake,0,6520725.story as at March 25, 2011</ref>.
+
 
+
=== Seawater Used For Cooling Increases Risk Of Additional Incidents ===
+
Japan's defense ministry said that US-American officials had expressed grave concern that the saltwater could cause equipment to seize up and corrode, making resolution of the situation even more difficult<ref name="latimes" />. A confidential paper dated to March 26 of the US ''Nuclear Regulatory Commission'' based on information of US engineers sent to Japan to support the emergency activities at Fukushima expresses concerns about an "array of new threats" at the Fukushima NPP, the ''New York Times'' uncovered April 5 including assessments about the possibility of new explosions due to the release of hydrogen and oxygen from seawater pumped into the reactors in order to cool the core down<ref name="nytimes_array">http://www.nytimes.com/2011/04/06/world/asia/06nuclear.html?_r=1 as at April 6, 2011</ref>. These blasts could lead to more serious releases of radiactivity destroying those barriers keeping it yet inside<ref name="nytimes_array" />. The water flow in unit 1 is "severely restricted and likely blocked due to slumping fuel and salt from seawater used to cool the wrecked reactors probably blocking the circulation pathways, the paper describes<ref name="nytimes_array" />. The US engineers also suspect fragments or particles of nuclear fuel coming from the spent fuel pools above the reactors were blown "up to one mile from the units"<ref name="nytimes_array" />. This would mean the spent fuel ponds have been much more seriously damaged by the earlier hydrogen explosions than admitted to public by now<ref name="nytimes_array" />.
+
 
+
=== Nuclear Inventory Of Fukushima Higher Than Chernobyl ===
+
According to the German news magazine ''Spiegel'' altogether more than 2,500 tons of uranium and plutonium are situated at Fukushima<ref name="spiegel_pu" />. ''Bellona'' informed about 1,760 tons stored in Fukushima stressing the fact that this potential threat is even higher than the Chernobyl catastrophe, where 180 tons were kept<ref name="bellona_russiafareast">http://www.bellona.org/articles/articles_2011/radiation_crisis_widespread as at April 5</ref>, facts confirmed by the Austrian ''Central Institute for Meteorology and Geodynamics'' on March 24<ref name="aljazeera_nosafelevels" /> and by 16 Japanese scientists in a statement of April 1 saying units 1-3 contain much more radioactive substances than the Chernobyl NPP did<ref name="japantimes_overcoming" />. A report from the ''New York Academy of Sciences'' testified 985,000 people to have died between 1986-2004 due to the Chernobyl disaster<ref name="aljazeera_nosafelevels" />. April 8, the ''International Physicians for the Prevention of Nuclear War (IPPNW)'' launched a study showing 600 million people in Europe have been affected by the Chernobyl disaster.<ref>http://www.ippnw.de/commonFiles/pdfs/Tschernobyl_Studie_2011_web.pdf as at April 9, 2011</ref>.
+
 
+
A ''TEPCO'' spokesman informed April 12 that the total amount of radiation released at Fukushima may exceed Chernobyl's<ref name="smh_sinister" />. Prof. Sebastian Pflugbeil, president of the ''Gesellschaft für Strahlenschutz'', stated in an interview to the German television ARD on April 12, that the nuclear meltdown of 4 reactors in NPP Fukushima Daiichi is worse than the reactor explosion and nuclear meltdown of Chernobyl, because in Fukushima there is more reactor inventory of uranium and plutonium involved<ref name="ard_2011_04_12" />. He is concerned, that the local area around Fukushima will be higher radioactive contaminated than in Chernobyl<ref name="ard_2011_04_12">http://www.tagesschau.de/ausland/japan834.html as at April 12, 2011</ref>.
+
 
+
=== Collapsed MOX Reactor Is Particular Risk ===
+
Around 9 PM UTC Saturday March 12 evening ''Reuters'' informed about Fukushima I ''Daiichi'' unit 3 that "the emergency cooling system is no longer functioning (...) as an official of the Japan Nuclear and Industrial Safety Agency told a news conference"<ref>http://www.reuters.com/article/2011/03/12/us-japan-quake-nuclear-cooling-idUSTRE72B3GI20110312 as at March 12, 2011</ref>. "This is of particular concern since, unlike all of the other reactors in trouble, Unit 3 has been using plutonium-based MOX (mixed oxide) fuel<ref name="naturalnews_ragingmeltdowns" /> since September 10, 2010. Plutonium is the most toxic chemical known to science<ref name="naturalnews_ragingmeltdowns" />. MOX fuel elements contain 7-8% of it<ref name="wikipedia_mox">http://de.wikipedia.org/w/index.php?title=MOX-Brennelement&oldid=87101523 as at April 1, 2011</ref>. Consequences of an accident at a MOX-powered reactor would be even more severe than at a more typical uranium-powered reactor<ref name="bbc_busby">http://news.bbc.co.uk/today/hi/today/newsid_9423000/9423929.stm as at March 28, 2011</ref>", says the ''Nuclear Information and Resource Service''<ref name="nirs">http://www.nirs.org/reactorwatch/accidents/Fukushimafactsheet.pdf as at March 13, 2011</ref> On March 13 the chief Cabinet secretary of Japan's government informed that an explosion at unit 3 of Fukushima 1 is possible to occur, but that they wouldn't expect a meltdown to happen<ref>http://english.kyodonews.jp/news/2011/03/77319.html as at March 13, 2011</ref><ref>http://www.bbc.co.uk/news/world-asia-pacific-12724953 as at Sunday March 13, 2011</ref> ''(however they want to be sure about that after the last days' experiences...)''. Several attempts to cool the reactor core failed until the late evening of Sunday<ref name="contratom" />, it eventually exploded Monday morning at 2.01 AM UTC<ref>http://english.kyodonews.jp/news/2011/03/77606.html as at March 14, 2011</ref><ref>http://www.youtube.com/watch?v=vMCa-Zo_ZEU&sns=fb as at March 14, 2011</ref>. [http://www.nirs.org NIRS] believes there are now multiple meltdowns in progress along with significant releases from irradiated fuel pools<ref name="nirs" />.
+
 
+
As the officially admitted radiation rate of 20 rems/hour (10,000 times above normal) affecting three workers at unit 3 on March 23 would not be high enough to cause the burns that were reported on them, there is suspicion that the rates were even higher. Radioactive elements were found in the water that are not normally found in reactor cooling water. This has led to new open speculation among government and utility officials that the core of unit 3 has been breached<ref name="naturalnews_ragingmeltdowns" /> and primary containment has failed (most observers have suggested this for several days, ''NIRS'' said)<ref name="nirs" />. The possibility of an even more severe environmental contamination was announced by Japanese officials on March 25 due to a suspected fracture of the unit 3 reactor core, a ''NISA'' spokesman was quoted by ''AP''<ref name="presstv" />. Since March 11 the operator is struggling to cool the unit containing 170 tons of MOX fuel<ref name="presstv" />. The damage could have been caused by the hydrogen explosion of March 14 blowing up the outer containment<ref name="presstv" />. High-level radiation is suspected to be leaking from the number three reactor core<ref name="presstv_deteriorate">http://www.presstv.ir/detail/171599.html as at March 26, 2011</ref>.

+
As reported on March 28, plutonium isotopes 238, 239 and 240 have been found<ref name="spiegel_rekordwerte" /><ref name="spiegel_pu">http://www.spiegel.de/wissenschaft/technik/0,1518,753770,00.html as at March 29, 2011</ref> by ''TEPCO'' in the soil at five locations at Fukushima I ''Daiichi''<ref name="bellona_russiafareast" />. One sample of plutonium-238, according to TEPCO, was measured at 0.54 Bq/kg of soil, and the mix of plutonium-239 and -240 in two other samples measured 1.2 Bq/kg<ref name="bellona_russiafareast" />. It must come from the fuel rods, the NPP operator suspects and chief Secreatry of the Japanese cabinet Edano agrees adding this would confirm a fuel meltdown has occured<ref name="bellona_russiafareast" />. In case it reachs the human body it can cause serious health damages - already small quantities can lead to high radiation affects as plutonium can be accumulated in bones and liver causing cancer<ref name="spiegel_pu" />.<ref name="spiegel_plutonium">http://www.spiegel.de/panorama/0,1518,753662,00.html as at April 2, 2011</ref> The breach of the containment of the reactor must be serious, as plutonium is a heavy element not being able to easily escape, a ''NISA'' speaker explained<ref name="spiegel_pu" />. Already March 21 and 22 ''TEPCO'' had detected plutonium, but told these findings not before March 28<ref name="spiegel_pu" />. According to former boss of the German atomic energy authority, Wolfgang Renneberg, the plutonium contained in unit 3 of Fukushima could become a deadly threat if it would be blown out of the reactor for instance by an explosion<ref name="spiegel_pu" />. In this case it would be spread widely and possibly be breathed in by humans<ref name="spiegel_pu" />. It could also end up in the food chain and eventually also in the human body, if plutonium would be washed into the ocean, Renneberg said<ref name="spiegel_pu" />.

=== Connected additional accidents in other atomic facilities ===
+
Several other nuclear Japanese facilities are faced to serious safety issues as a result of the tsunami and earthquakes: the '''reprocessing unit Rokkasho''' ''(difficulties with cooling systems)'', the '''NPP Fukushima 2 Daini''' ''(fire, failing cooling systems - atomic power emergency declared)'', the '''NPP Tokai''' ''(two of three emergency power generators failed)'' and the '''NPP Onagawa''' ''(fire, leakage - atomic power emergency declared)''<ref name="greenpeace" /><ref name="contratom" />.
+
 
+
As a result of a new heavy 7.2 earthquake, two of three power supplies failed at the Onagawa NPP, ''NISA'' informed April 7<ref name="spiegel_erdbeben" />. A small amount of radioactively contaminated water splashed from fuel pool at all three reactors, operator ''Tohoku Electric Power Company'' informed<ref name="faz_onagawa" /><ref name="radiofreeeurope_onagawa">http://www.rferl.org/content/water_leaks_at_nuclear_plant_after_japan_quake/3550971.html as at April 8, 2011</ref>. At one unit, the company said, about four liters of middle radioactive water were spilling from the spent fuel pool<ref name="yahoo_minister">http://news.yahoo.com/s/afp/20110409/wl_asia_afp/japandisasteraccidentnuclear as at April 9, 2011</ref>. Besides, leaks were found at eight (other source: five<ref name="radiofreeeurope_onagawa" />) spots at the plant<ref name="faz_onagawa" />. Although the power plant has been shut down after the earthquake on March 11<ref name="radiofreeeurope_onagawa" /><ref name="yahoo_minister" />, the fuel still needs to be cooled<ref name="faz_onagawa" />. Yet the emergency power seems to be ensured, but due to the aftershock cooling was interrupted briefly<ref name="faz_onagawa" />. The blowout panels, a device at the turbine building intended to controll the pressure, was also damaged by the quake<ref name="radiofreeeurope_onagawa" /><ref name="faz_onagawa" />. At the Higashidori NPP and at the Rokkasho reprocessing unit the external electricity supply was interrupted, but the emergency power systems worked, Kyodo reported<ref name="faz_onagawa" />.

+
=== Health Impacts Of The Catastrophe ===
+
<span style="font-weight:bold; font-style:italic">"News reports mention Iodine-131 and Cesium-137, not because they are the only radioactive elements discharged from the stricken reactors in Fukushima, but because they are the easiest to detect and measure," ''Physicians for Global Survival'' explained in a press release April 1<ref name="vancouverobserver_doctors">http://www.vancouverobserver.com/world/canada/2011/04/01/doctors-express-deep-concern-about-fukushima-impacts-canada as at April 9, 2011</ref>. What is measured usually is the gamma radiation iodine produces itself and cesium produces it through its decay product barium-137<ref name="vancouverobserver_doctors" />. Alpha and beta emitters are much more difficult to detect<ref name="vancouverobserver_doctors" />. It is important to be aware that the isotopes mentioned in the publications of ''TEPCO'' or ''NISA'' are not the only ones emitted from Fukushima<ref name="vancouverobserver_doctors" />.</span>
+
 
+
<span style="font-weight:bold; font-style:italic">Tiny amounts of breathed in plutonium isotops are capable of causing lung cancer<ref name="spiegel_dimension" />. Plutonium is a substantial alpha emitter, some of its isotopes also radiate beta rays, while the gamma radiation is on an insignificant level<ref name="wikipedia_pu" />. Unfortunately, neither the usual [[Geiger counter]]<ref name="bbc_busby" /> nor the official radiation measuring systems are able to detect plutonium. Thus, the published data of radiation detection doesn't reflect the actual radioactivity threat<ref name="wikipedia_pu" />. The isotope plutonium-239 is generated in considerable amounts in nuclear power plants and has a halftime of about 24,000 years<ref name="wikipedia_pu">http://de.wikipedia.org/w/index.php?title=Plutonium&oldid=87164763 as at April 1, 2011</ref>.</span>
+
 
+
According to the US Department of Energy, no level of radiation is so low that it is without health risks<ref name="aljazeera_nosafelevels">http://english.aljazeera.net/indepth/features/2011/04/20114219250664111.html as at April 7, 2011</ref>. The "background radiation, downplayers of nuclear risks often refer to, has been increased over decades for instance by about 2,000 nuclear tests releasing radioactive particles to the environment<ref name="aljazeera_nosafelevels" />. Jacqueline Cabasso, the Executive Director of the Western States Legal Foundation explained in an interview at the beginning of April: "That means all this talk about what a worker or the public can withstand on a yearly basis is bogus. There is no safe level of radiation exposure. These so-called safe levels are coming from within the nuclear establishment."<ref name="aljazeera_nosafelevels" /> The ''Western States Legal Foundation'' monitors and analyzes U.S. nuclear weapons programs and policies<ref name="aljazeera_nosafelevels" />. In 2006 the United States ''National Academy of Sciences (NAS)'' published a report on "Biological Effects of Ionizing Radiation" (BEIR report) of an expert panel: "The committee concludes that the current scientific evidence is consistent with the hypothesis that there is a linear, no-threshold dose-response relationship between exposure to ionizing radiation and the development of cancer in humans."<ref name="aljazeera_nosafelevels" />.

==== Harmed workers at Fukushima ====
+
One worker died as a direct result of the explosion of Fukushima 1 unit 1, three others were injured and sent to hospital. A contractor had been found unconscious and two workers of a "cooperative firm" had been injured.<ref name="wnn">http://www.world-nuclear-news.org/RS_Battle_to_stabilise_earthquake_reactors_1203111.html as at March 12, 2011</ref> At the same time at unit 3 one worker received a high radiation dose, and the whereabout of two workers remained unknown<ref name="wnn" />, while as a result of the explosion on March 14 six soldiers from the Japanese Central Nuclear Biological Chemical Weapon Defence Unit died<ref name="telegraph_fifty">http://www.telegraph.co.uk/news/worldnews/asia/japan/8408863/Japan-tsunami-Fukushima-Fifty-the-first-interview.html as at March 30, 2011</ref>. "Fukushima Prefecture revealed that there are an additional 19 individuals who have received radiation doses. This brings the total to 22 people. According the ''NISA'', there is a possibility that 160 individuals living in the vicinity of the nuclear power plants (at Futabe<ref name="spiegel_13marz" />) have received radiation doses, Mainichi reported on Sunday March 13<ref>http://mainichi.jp/select/weathernews/20110311/news/20110313k0000e040033000c.html as at March 13, 2011 via http://www.greenaction-japan.org/modules/wordpress1/index.php?p=2 as at March 13, 2011</ref>. While Japanese authorities<ref name="japantimes1" /><ref>http://www.nisa.meti.go.jp/english/files/en20110323-2-5.pdf as at April 10, 2011</ref> and the operator<ref name="spiegel_fish" /><ref name="monitor_ausserkontrolle">http://www.wdr.de/tv/monitor/sendungen/2011/0407/fukushima.php5 as at April 8, 2011</ref> as well as an IAEA spokesman and recently also some BBC correspondents as well as the British "The Guardian"<ref>http://www.guardian.co.uk/commentisfree/2011/apr/05/anti-nuclear-lobby-misled-world as at April 7, 2011</ref> were downplaying the risks of the radiation released pretty soon after the first explosions at Fukushima, the legal exposure limit for the workers was raised on Wednesday from 100 to 250 millisieverts in Japan<ref name="bbc" />. The atomic industry as well as Japanese government are reproached to hold back information about the radiation doses and risks in connection to the disaster<ref name="spiegel_dimension" />.
+
 
+
Two workers had to be sent to hospital on March 24 after receiving a dose of 170 to 180 mSv of radiation after stepping into contaminated water (2-6 Sv<ref name="telegraph_fifty" /><ref name="spiegel_inwater" />) at unit 3 radioactive 10,000 times the normal level<ref name="xinhuanet">http://news.xinhuanet.com/english2010/world/2011-03/25/c_13798306.htm as at March 29, 2011</ref><ref name="latimes" /><ref name="chicagotribune1" /> - up to 24 times the workers’ entire yearly exposure limits, even on the raisen emergency levels prescribed in reaction to the disaster<ref name="telegraph_fifty" />. "If this water was absorbed by their bodies in any way, those two workers will almost certainly die", the reporters of the first interview with the "Fukushima Fifty" set out<ref name="telegraph_fifty" />. Another one was affected, but not sent to hospital<ref name="latimes" /><ref name="chicagotribune1">http://www.chicagotribune.com/news/nationworld/la-fgw-japan-quake-radiation-20110325,0,7432140.story as at March 25, 2011</ref>. The workers sustained skin burns caused by beta rays<ref name="xinhuanet" />.
+
 
+
The so-called "Fukushima Fifty" are the 50 people sent to the reactor to save as much as possible to reduce the deadly impact of the atomic catastrophe. It must be called a sacrifice of these people, as they are exposed to high radiation levels close to the blown up reactors. "We will die", the mother of one of them quoted her son in an interview with ''Fox News''. They would have accepted to die soon due to radiation sickness or later owing to cancer, he said.<ref name="gmx_sterben">http://www.gmx.net/themen/nachrichten/erdbeben/247fsls-wir-werden-sterben as at April 5, 2011</ref> According to the German state TV ''ZDF'' some 800 workers are involved to the emergency operations at the Fukushima NPP one and a half months after the disaster occured<ref name="zdf_protests">http://www.zdf.de/ZDFmediathek/beitrag/video/1329118/Japaner-protestieren-gegen-Atomkraft#/beitrag/video/1329118/Japaner-protestieren-gegen-Atomkraft as at May 10, 2011</ref>. ''ZDF'' reported May 8 that the continous medical examination of the workers didn't start before a couple of days ago<ref name="zdf_protests" />.
+
 
+
As of April 7, ''TEPCO'' said 21 workers to have each been exposed to cumulative radiation levels of more than the usual limit for nuclear industry employees in case of an emergency of 100 millisieverts, which was raised to 250 millisieverts due to the Fukushima catastrophe<ref name="nytimes_workers">http://www.nytimes.com/2011/04/10/world/asia/10workers.html?pagewanted=1&_r=3 as at April 13, 2011</ref>.
+
 
+
Reports indicate that a number of Japanese people who lived between 200 and 350 kilometers away from the plant have been hospitalized for exposure to radioactive materials, ''PressTV'' wrote March 25<ref name="presstv" />. By March 26 the news agency ''Kyodo'' reported 17 workers suffering radiation exposure since the beginning of the atomic catastrophe taking into account only accidents with levels over 100 mSv (former limit for radiation exposure of workers in the nuclear industry in Japan)<ref name="spiegel_inwater" />.
+
 
+
''TEPCO'' boss Masataka Shimizu has been admitted to hospital, the Fukushima operator told to the press on March 30. He is suffering high blood pressure and feeling of dizziness, the company informed.<ref name="spiegel_rekordwerte" /><ref name="welt_shimizu" /> He had not shown up to public for about two weeks<ref name="spiegel_schlampt" />, causing rumors he could have commited suicide or escaped abroad<ref name="welt_shimizu" />.
+
 
+
==== Radiation detection at the crashed NPP ====
+
As reported on March 27 high amounts of iodine-134 (52 minutes half-time) have been detected at unit 2 indicating a damage of the reactor core, as ''TEPCO'' informed<ref name="tagesschau_Jod-134">http://www.tagesschau.de/ausland/fukushima326.html as at April 15, 2011</ref>. Near the NPP airborne radiation was detected at 4-times the legal limits, ''Aljazeera'' reported April 4<ref name="aljazeera_nosafelevels" />.
+
 
+
''RT Moscow'' reported on May 10 a couple of days ago the government tried to enter unit 1 for the first time after the explosions at Fukushima I. Due to extremly high radiation readings leading to exceed the permitted life time exposure of a worker within 10 minutes, the visit could not be successfully finished<ref name="rtmoscow_return" />.
+
 
+
==== Radiation detection outside the NPP in Japan ====
+
On March 13 the news agency Kyodo announced radioactivity readings 400 times normal in the province of Miyagi.<ref name="spiegel_13marz">http://www.spiegel.de/wissenschaft/technik/0,1518,750628,00.html as at April 15, 2011</ref>
+
 
+
98 people tested in the Fukushima prefecture by March 24 were above limits (87,813 people screened in total)<ref name="cnn" />. Hundreds of evacuees from areas close to the blown up Fukushima NPP are sent back by medical institutions and emergency shelters fearing their potential radioactive contamination, as reported on March 30<ref name="telegraph_turnaway">http://www.telegraph.co.uk/news/worldnews/asia/japan/8416302/Japan-nuclear-crisis-evacuees-turned-away-from-shelters.html as at March 31, 2011</ref>. Without certificates proofing them to be not contaminated refugees are rejected by hospitals and temporary shelters<ref name="telegraph_turnaway" /><ref name="spiegel_inwater" />.
+
 
+
By Thursday March 17, the available data about radiation from Fukushima I show releases of already "about a tenth of what was released from the Chernobyl-4 reactor in Ukraine in 1986", experts of the French IRSN (Institute of Radiological Protection and Nuclear Safety) informed.<ref>http://www.platts.com/RSSFeedDetailedNews/RSSFeed/ElectricPower/6916290 as at March 19, 2011</ref> The Austrian Central Institute for Meteorology and Geodynamics (ZAMG), which is advising the International Atomic Energy Agency, reported on March 23 that releases of radioactive Cesium (hazardous life: 300-600 years) from Fukushima now are 20-60% those of Chernobyl; releases of iodine-131 are at 20% Chernobyl releases<ref name="nirs" /><ref>http://www.zamg.ac.at/aktuell/index.php?seite=1&artikel=ZAMG_2011-03-23GMT10:57 as at March 25, 2011</ref>. According to Agence France-Presse ''France’s Nuclear Safety Authority'' says that local contamination in the area is a problem that will remain for "decades and decades"<ref name="nirs" />. The radiation measuring station in Takasaki/Japan shows figures of radioactive substances from Fukushima to continue going up and down, a senior of the ''CBTBTO'' said on March 25. It could not be said that the radiation would be on the decrease, they continued<ref name="kyodo25">http://english.kyodonews.jp/news/2011/03/80907.html as at March 25, 2011</ref>. The released radioactivity comes out of the reactors rather than from spent fuel ponds, IAEA officials said, noting the composition of the radioactive isotopes<ref name="presstv_iaea" />. By March 29 radioactive leaks have been detected at four of the plant's six reactors<ref name="xinhuanet" />.
+
 
+
On March 30 ''NISA'' informed to have detected radiation about 2 MBq/m² in the soil nearby the village of Iitate about 40 km northwest of Fukushima I, twice the IAEA limit to prompt an evacuation of residents, and also twice the level that prompted to evacuate people near Chernobyl 25 years ago<ref name="aljazeera_nosafelevels" />.<ref name="japantimes1" /><ref name="abc_radiationspreads">http://www.abc.net.au/news/stories/2011/03/31/3178263.htm as at March 31, 2011</ref><ref name="terradaily_evacuate" /> One day later, ''NISA'' announced not to intend evacuating the village as this would have been "only a limited sample and a single reading"<ref name="terradaily_evacuate">http://www.terradaily.com/reports/Japan_says_no_need_to_evacuate_village_near_nuclear_plant_999.html as at April 5, 2011</ref>. Greenpeace, who are taking independent readings on-site<ref>http://www.greenpeace.at/strahlenteam.html as at April 6, 2011</ref><ref>http://blog.greenpeace.de/blog/2011/04/05/moin-moin-aus-japan-2/ as at April 7, 2011</ref> since March 26<ref>http://www.greenpeace.de/themen/atomkraft/nachrichten/artikel/greenpeace_strahlenexperten_bei_fukushima/ as at April 7, 2011</ref>, detected up to 10 μSv/h in Iitate and up to 100 μSv/h nearby Tsushima, as they published March 30<ref name="spiegel_rekordwerte" />. After a couple of days staying in these regions, residents would have received the maximum legal annual limits<ref name="spiegel_rekordwerte" />. A couple of days later, April 4, the international ''Greenpeace'' expert team measured 12.2-15.6 μSv/h in Tsushima 40 km from the stricken Fukushima I ''Daiichi'' NPP<ref name="facebook_gpphotos" />, while they detected 3.7 μSv/h at a brocoli field in Minamisoma, 25km from nuclear power plant<ref>https://www.facebook.com/greenpeacepicdesk?sk=wall#!/album.php?id=114938651859052&aid=55356 as at April 7, 2011</ref>. April 6 Greenpeace published new readings: up to 4.5 μSv/h in Minamisoma and up to 47 μSv/h in Tsushima<ref name="gp_fieldteam">http://www.greenpeace.org/international/en/news/Blogs/makingwaves/field-team-finds-high-levels-of-contamination/blog/34118 as at April 10, 2011</ref>. The IAEA confirmed March 26 radioactive fallout in 17 Japanese prefectures, with seven of them showing daily fallout readings of iodine-131 up to 500 Bq/m² and of cesium-137 up to 100 Bq/m²<ref name="bellona_russiafareast" />. According to the IAEA the highest readings were found in the Yamagata prefecture with 7,500 Bq/m² of iodine-131 and 1,200 Bq/m² of cesium-137, while in the area of 30-40 kilometers around the Fukushima NPP contamination hot spots of 30,000 to 3,100,000 Bq were detected<ref name="bellona_russiafareast" />.
+
 
+
"Weak concentrations of radioactive iodine-131 and cesium-137 do not justify announcements that there are no health risks. If there are radioactive particles in the atmosphere, then they can be ingested by someone," who may cause cancer, Vladimir Slivyak, co-chair of ''Ecodefence'' said<ref name="bellona_russiafareast" />. The Japanese nuclear industry author Hiroshe Takashi agreed with Slivyak’s assessment in an interview earlier, saying that comparing radiation released at Fukushima Daiichi to CT scans and x-rays was useless<ref name="bellona_russiafareast" />. The radiation of about 1 Sv/h measured March 27 by ''TEPCO'' at unit 2 could possibly lead to dead, ''Spiegel online'' reported. ''EPA'', the US environment protection authority, assessed this dose to produce serious bleedings (internal hemorrhaging<ref name="aljazeera_nosafelevels" />. The highly radioactive water probably comes almost certainly from the reactor core, Secretary Yukio Edano said.<ref name="spiegel_inwater" /> March 30 the ground water beneath the NPP was announced to be at 430 Bq/cm³ - 10,000 times above legal limits<ref name="gmx_sterben" />. One day later, March 31 iodine-131 4,385 times the legal level was detected in a sample taken near the Fukushima NPP<ref name="presstv_china" />. On April 2, ''NHK'' published that, refering to ''TEPCO'', a 20 cm crack has been found in a trench full of contaminated water leaking from the containment of unit 2<ref name="cnn_expert" /><ref name="spiegel_riss" />. There, highly radioactive water above 1 Sv/h escapes at 7 t/d directly to the ocean<ref name="cnn_expert" /> causing maybe the [[#Radiation levels in the ocean|extremely high radiation readings in the sea]] nearby the reactors<ref name="spiegel_riss" /><ref name="spiegel_tokyo">http://www.spiegel.de/wissenschaft/technik/0,1518,754683,00.html as at April 5, 2011</ref><ref name="aljazeera_nosafelevels" />. The crack was probably caused by the March 11 earthquake, ''TEPCO'' speaker Osamu Yokokura said, meaning that the radioactive water possibly leaks since the very beginning of the catastrophe<ref name="spiegel_tokyo" />. According to ''TEPCO'' the radiation in distance of 60 cm from the pit containing the highly radioactive water reads still 0.4 Sv/h<ref name="spiegel_tokyo" />. April 6 ''TEPCO'' announced, confirmed by the government's chief Secretary Edano<ref name="voanews_newrisk">http://www.voanews.com/english/news/Japanese-Plug-Nuclear-Plant-Leak-Now-Face-Hydrogen-Build-up-119311074.html as at April 7, 2011</ref>, to have eventually succeeded in its attempts to seal the crack with 1,500 l of "water glass" (sodium silicate)<ref name="cnn_expert" /> after they failed during the last days trying a variety of materials<ref name="nytimes_nitrogen" /><ref name="latimes_success" /><ref name="rponline_nitrogen" /><ref name="cnn_expert" />. ''TEPCO'' announced on 21th of April to have calculated the total amount of leaked highly radioactive water to be 520 t, if the leak started 1st of April and ended on 6th of April 2011 <ref name="tepco_20110421">http://www3.nhk.or.jp/daily/english/21_35.html as at April 21, 2011</ref>. "The trench, however, is still getting radioactive liquid from the unit 2 containment building itself", Nuclear engineer Arnie Gundersen said in an interview with CNN April 5<ref name="cnn_expert" />. Hidehiko Nishiyama, a ''NISA'' spokesman, said April 6 that the now-contained water "may lead to more leakage somewhere else", while ''TEPCO'' informed on April 7 the water level in the basement of the turbine plant to have rosen about 4 centimeters since sealing the leak<ref name="cnn_widen" />. Meanwhile, the water level returned to its previous depth, indicating to escape through another opening, a ''NISA'' representative said April 7<ref name="globalsecuritynewswire" />.

On March 24 Japanese officials said that infants - even outside the evacuation zone - could have received a dose of 10 rems to their thyroids from iodine-131 over the past two weeks. This would apply to infants who had stayed outdoors every day. The radiation levels remained far above normal. The ''Nuclear Information and Resource Service (NIRS)'' pointed out that all of the levels of the surrounding communities are far above background and above levels allowable for long-term human habitation. NIRS stressed the fact that all of the monitoring locations are outside the current evacuation zone, in most cases many miles outside.<ref name="nirs" /> One of the radiation monitoring websites from Japan is commenting the status "under suryey" of the collapsed reactors to be a synonym for being "under censorship". [http://www.mext.go.jp/component/english/__icsFiles/afieldfile/2011/03/21/1303997_2119.pdf Readings of March 21] published by the Japanese ''Ministry of Education, Culture, Sports, Science and Technology (MEXT)'' showed up to 111 Mikrosieverts per hour 30 kilometers from the site - thus, the maximum allowable dose to public would be reached in about 9 hours<ref name="nirs" />.

On Saturday March 19 the Japanese government confirmed high radiation in spinach and milk near the nuclear power plant<ref name="nytimes19">http://www.nytimes.com/2011/03/20/world/asia/20japan.html?_r=1 as at March 19, 2011</ref>. The spinach was growing some 60 kilometers from the site<ref name="nirs" />. Vegetables from the Fukushima region and the also radioactively affected Ibaraki area south of Fukushima had nevertheless been sold in Tokyo, the New York Times reported<ref name="nytimes19" />. A couple of days later, on March 23, Japan's Prime Minister urged consumers not to eat certain types of food from the region surrounding the nuclear facilities and also expanded a shipment ban<ref name="chicago2">http://www.chicagotribune.com/news/nationworld/la-fg-japan-tokyo-water-20110324,0,7046959.story as at March 25, 2011</ref>. Also significantly contaminated rape had been detected on March 20 from regions not affected by increased radiation yet<ref name="spiegel_water" />. Radioactively polluted beans from Japan have been found in Taiwan, too<ref name="spiegel_water" />. April 5 in spinach samples radioactive particles were detected in three Chinese provinces<ref name="globalsecuritynewswire" />.

The ''U.S. Food and Drug Administration'' has banned import of milk and vegetables from four Japanese prefectures to the United States<ref name="nirs" /><ref>http://www.chicagotribune.com/news/nationworld/sc-dc-japan-food-imports-20110322,0,4153032.story as at March 25, 2011</ref>.

A couple of days after the explosions at Fukushima I ''Daiichi'' the European Union has raisen the legal limits for radiation in food imported from Japan<ref name="welt_shimizu" /><ref name="spiegel_tokyo" />. The new limits for food imports from Japan coming into force in the EU after the Fukushima disaster with the 1987 adopted Chernobyl emergency decree ''EURATOM  No. 3954/87'' are an "unacceptable high strain to EU citizens", independent radiation expert Thomas Dersee and publisher to the magazine ''Strahlentelex<ref>http://strahlentelex.de/ as at March 31, 2011</ref>'' says. The latest allowable contamination levels in the European Union are several times the Japanese limits leading to the absurd situation that radioactive products being not permissible for consumption in Japan could be imported to the EU. Cesium limits for milk are 200 Bq in Japan and 1,000 Bq in the EU, for meat they are 500 Bq in Japan and 1,250 Bq in Europe, while iodine in milk is limited to 300 Bq in Japan and to 500 Bq in the EU. Plutonium is restricted to 1 Bq in milk and to 10 Bq in meat in Japan, in contrast to the European Union's limitations allowing plutionium up to 20 Bq in milk and up to 80 Bq in meat.<ref>http://www.taz.de/1/zukunft/umwelt/artikel/1/eu-tolerant-bei-strahlen/ as at March 31, 2011</ref> As a result of the protests against raising the European radiation limits, the EU wants to regain consumers confidence when they announced April 5 to adapt the limits to the stricter regulations of Japan<ref name="spiegel_fish" />. The EU imports annually food to the value of some 260 million euros<ref name="spiegel_fish" />.

Contaminated tap water was detected in the Fukushima prefecture on March 20 causing to warn the population not to drink it as the radiation levels could be too high<ref name="spiegel_water">http://www.spiegel.de/panorama/0,1518,752037,00.html as at March 25, 2011</ref>. Increased radiation values had been found already beforehand in Tokyo and other regions<ref name="spiegel_water" />. Radioactive iodine-131 was found in Tokyo’s<ref name="chicago2" /> and in five surrounding cities' water supply at twice the allowable level for infants<ref name="presstv_tabwater" /><ref name="cnn" />, the government told on March 22 advising not to let infants drink tap water or use it in formula<ref name="nirs" /><ref name="chicago">http://www.chicagotribune.com/news/nationworld/la-fgw-japan-quake-radiation-20110325,0,7432140.story as at March 25, 2011</ref>. Tap water levels exceeding 300 becquerels were found in the Fukushima prefecture<ref name="chicago2" />. The government was distributing bottled water to 80,000 households with infants younger than 12 months<ref name="chicago" />. Meanwhile, radioactive iodine is suspected in the tap water of 12 prefectures, Japan's education, science and technology ministry informed, not including Fukushima and Miyagi, where measurements aren't being taken, CNN reported March 26<ref name="cnn" />. The range of levels of radioactive iodine on March 25 in water treatment facilities serving the cities of Tokaimura and Hitachi was from 31 to 97 becquerels per kilogram of water<ref name="cnn" />. The official treshold for tap water is 100 becquerel for infants up to one year and 300 becquerel for adults<ref name="cnn" />, though tresholds don't show harmlessness as they reflect the politic's willingness to burden the public with a threat in relation to the economical costs. Additionally, the risk model used by most states on earth has been falsified, the ''European Committee on Radiation Risk (ECRR)'' states pointing to a new risk model they developed on the basis of latest scientifical findings<ref>http://llrc.org/ as at March 26, 2011</ref><ref>http://www.euradcom.org/ as at March 26, 2011</ref>.

April 4 officials found iodine-131 concentrations above 4,000 Bq/kg and cesium-137 at 447 Bq in fish ("sand lance") caught about 50 miles south of the Fukushima NPP close to Kitaibaraki<ref name="latimes_success" />. In reaction to the detection fishing of sand lances had been suspended causing local fishermen to demand ''TEPCO'' for compensation<ref name="latimes_success" />, while fishing in the 20 kilometer zone around the NPP has been prohibited by the government, too<ref name="rponline_nitrogen" />. People won't buy fish and seafood from Fukushima for a long time, local fishermen assume<ref name="spiegel_fish" />.
+
 
+
At a press conference on April 5 chief Secretary of the Japanese cabinet Edano announced new legal limits for fish and seafood of 2,000 Bq/kg - similar to German figures<ref name="spiegel_fish" />. Until that day there were no specific regulations for radiation in these products in Japan<ref name="spiegel_fish" />.

==== Radiation levels in the ocean ====
+
High radiation levels have been detected in the Pacific Ocean waters near to Fukushima. Iodine-131 at 50 Bq/cm³<ref name="bellona_russiafareast" /> - 1,250.8 times the legal limit - 330 meters offshore near unit 1 were announced by ''NISA'' on March 26<ref name="presstv_ocean">http://www.presstv.ir/detail/171675.html as at March 26, 2011</ref><ref name="cnn">http://edition.cnn.com/2011/WORLD/asiapcf/03/26/japan.nuclear.disaster/?hpt=T2 as at March 26, 2011</ref>, while cesium-134 was detected at 7 Bq/cm³ (117 times normal) and cesium-137 at 7.2 Bq/cm³ (79.6 times normal)<ref name="bellona_russiafareast" />. "This is a relatively high level", a ''NISA'' spokesman said in a press conference<ref name="presstv_ocean" />. These high levels indicate a direct leakage into the ocean, while it seems to be unlikely caused by atmospheric emissions or rain, an operator spokesman said<ref name="cnn" />. ''TEPCO'' had announced March 22 that the seawater reading was 126 times above the legal level, while on Thursday it was 145 times the legal level<ref name="presstv_ocean" />. The detected radiation levels continue rising: March 27 ''IAEA'' informed about iodine readings 1,850 times normal<ref name="tagesschau_Jod-134" />, March 29 ''NISA'' confirmed iodine-131 3,350 times the permitted levels in the seawater<ref name="telegraph_turnaway" />, one day later, it was 3,355 times higher radiation than normal<ref name="spiegel_rekordwerte">http://www.spiegel.de/wissenschaft/technik/0,1518,753933,00.html as at April 4, 2011</ref><ref name="RussiaToday_Busby" />, and on March 31 ''NISA'' published the levels of radioactive iodine-131 found in seawater near Fukushima 1 being 4,385 times the maximum tolerable amount<ref name="gmx_sterben" />, while also other radioactive materials were detected, such as cesium-134 at 783.7 times the maximum amount permitted, and cesium-137 at 527.4 times the legal limit<ref name="japantimes1">http://search.japantimes.co.jp/rss/nn20110331x1.html as at March 31, 2011</ref>. The readings of iodine-131 in the seawater near to the water intake of unit 2 had been 7,500,000 times the legal limit<ref name="spiegel_fish" /><ref name="aljazeera_chernobyl" /> and cesium-137 was detected at 1,100,000 times the legal limit on April 4, ''TEPCO'' informed one day later<ref name="nytimes_nitrogen" /><ref name="latimes_success" />. These readings were taken before ''TEPCO'' started to release 11,500 tons of radioactive water to the sea<ref name="aljazeera_chernobyl" />.
+
 
+
30 kilometers offshore radioactive iodine and cesium was detected, the ''IAEA'' reported online on Saturday<ref name="cnn" />. The Japanese ministry of science published on April 2 the detection of radioactive iodine in the sea 40 kilometers south the reactors double the legal limits<ref name="spiegel_tokyo" /><ref name="msnbc_threemileisland">http://www.msnbc.msn.com/id/21134540/vp/42351323#42351323 as at April 7, 2011</ref>.

As long as radioactive substances getting into the sea, radiation will be spread over the whole globe<ref name="spiegel_fish" />. They will be dilluted by the seawater and some isotopes like iodine-137 will disappear after some 80 days due to their half-life of some 8 days<ref name="wikipedia_jod">http://de.wikipedia.org/w/index.php?title=Liste_der_Isotope/5._Periode&oldid=86966015 as at April 7, 2011</ref>, but many others like cesium, plutonium and neptunium<ref name="faz_greenpeace" /> will remain for a long time or even decay to other dangerous radioactive isotops being a threat to the environment and human life. "It is extremely important to stop contaminated water leaking to the ocean", says Yoichi Enokida, professor at the university of Nagoya<ref name="spiegel_fish" />.

There are two big ocean currents crossing at Fukushima - a cold one from north and a warm one coming from the south<ref name="faz_greenpeace">http://www.faz.net/s/RubB08CD9E6B08746679EDCF370F87A4512/Doc~E1AEA512ECD6B4B73A32774BBBF7F00F3~ATpl~Ecommon~Scontent.html as at April 7, 2011</ref>. Both move to Hawaii and North America, but dividing to Alaska and Bering Sea<ref name="faz_greenpeace" />. These are important fishing areas, while the catch mostly would be processed in China and Russia<ref name="faz_greenpeace" />. Fish harvested there would reach Europe in some three months, Greenpeace expert Manfred Santen explained April 5<ref name="faz_greenpeace" />.

Particles of fallout from the Fukushima accidents were detected in western California on March 18 and in Iceland<ref name="xinhuanet" /> on March 20 and were expected in France and elsewhere in Europe, experts said on March 23<ref name="chicago2" /><ref name="kyodo25" />. The readings of the ''[http://www.ctbto.org/ Comprehensive Nuclear-Test-Ban Treaty Organization] (CTBTO)'' showed iodine-131 and xenon-133 proved also in Russia<ref name="welt_shimizu" />, Canada, USA and also in Sweden<ref><nowiki>http://www.bfs.de/de/ion/animation.gif</nowiki> as at March 25, 2011</ref><ref>http://www.zamg.ac.at/docs/aktuell/Japan2011-03-25_1600_E_2.pdf as at March 25, 2011</ref>. Another simulation shows that radioactive iodine-131 from Fukushima already ''(25/3/11)'' reached wide areas of Europe in very diluted amounts and will increase during the next couple of days<ref>http://www.zamg.ac.at/aktuell/index.php?seite=1&artikel=ZAMG_2011-03-25GMT15:41 as at March 25, 2011</ref>. Since March 24 radioactive iodine-131 has been detected in Germany, too, but on small levels, the German Ministry of Ecology informed<ref name="reuters_elections" /><ref name="reuters_radiation_de">http://de.reuters.com/article/domesticNews/idDEBEE72O0AR20110325 as at March 26, 2011</ref>. ''Deutscher Wetterdienst'' stations in Potsdam, Offenbach and Braunschweig found the fallout particles on a level of a millionth part of the normal background radiation<ref name="reuters_radiation_de" />. In Freiburg iodine-131 and xenon-133 had been detected March 25 - due to the measurement procedure taking one day it is likely that the particles reached the place already one day earlier<ref>http://www.badische-zeitung.de/freiburg/station-auf-dem-schauinsland-misst-radioaktives-jod-aus-japan--43275937.html as at March 26, 2011</ref>. The radioactive plume had been transported by winds via North America to Europe<ref name="reuters_radiation_de" />. By March 25 nearly all CTBTO stations in the northern hemisphere detected radioactive iodine-131 from Fukushima<ref><nowiki>http://www.bfs.de/de/ion/animation.gif</nowiki> as at March 29, 2011</ref>. From March 25 to March 26 the level of detected iodine-131 in Freiburg (D) increased by one order of magnitude<ref><nowiki>http://www.bfs.de/de/ion/aktivitaetskonzentrationen_jod.jpg</nowiki> as at March 29, 2011</ref>. March 28 South Korea informed Xenon-133 from Fukushima had been detected<ref name="spiegel_plutonium" /> as well as radioactive iodine and cesium were found in 14 of 244 tested products being imported March 19-29<ref name="welt_shimizu" />. Thailand detected increased readings of iodine-131 in imported sweet potatoes<ref name="welt_shimizu" />. By March 30 in most Chinese provinces radiation from Fukushima had been found<ref name="presstv_china" />, while an airplane coming from Japan had been found with increased radiation levels 22 times to normal already a couple of days after the beginning of the disaster<ref name="ftd" />.

Dr. Chris Busby at the ''European Committee on Radiation Risk (ECRR)'' told the public that the ECRR radiation risk model predicts 120,000 cancers worldwide based on the current known releases from Fukushima<ref name="nirs" />. Ground radiation levels at the Fukushima site are currently over 2,000 Microsievert per hour, and there are likely hot spots of far higher levels, ''NIRS'' assumes<ref name="nirs" />.

==== International reactions to fallout contamination ====
+
In connection to the Fukushima disaster, since March 16, the German ''Deutscher Wetterdienst'' ordered their stations not to publish data about radioactivity measurements autonomously. This stated Prof. Sebastian Pflugbeil, president of the ''Gesellschaft für Strahlenschutz'', to the news broadcasting N24<ref>https://www.facebook.com/video/video.php?v=144759748925071&comments as at March 23, 2011</ref>. The ''Gesellschaft für Strahlenschutz'' warned on March 23 about under-estimating the impacts and health risks of the radiation measured and published in Japan and spoke about levels comparable with the levels of radiation after the Chernobyl disaster 1986<ref>http://www.gfstrahlenschutz.de/pm110323.htm as at March 23, 2011</ref>. This assessment is shared by the ''Austrian meteorological institute'' studying the data coming in from the monitoring stations of the ''Comprehensive Test Ban Treaty Organization (CTBTO)''<ref>http://www.npr.org/2011/03/25/134833909/built-for-bombs-sensors-now-track-japan-radiation as at March 25, 2011</ref>.

Sailors have been supplied with iodine tablets by the city of Hamburg (D), the authorities announced on March 20<ref name="spiegel_water" />. In both harbour cities, Hamburg and Bremen (D), the authorities get prepared for emergency situations checking arriving ships from Japan for increased radiation readings<ref name="welt_shimizu" /><ref name="spiegel_tokyo" />. Car component importers in Germany announced to check their products for radiation before delivering<ref name="spiegel_tokyo" />.

Despite to former publications of the German Ministry of Environment the so-called "iodine blocker" ''potassium iodide'' tablets (German brand name "Kalium-Jodid") are not available for customers in Germany right now<ref>http://jodblockade.de/ as at March 24, 2011</ref>. An inquiry to a public pharmacy resulted in the information that this product meant to be used in an emergency situation hasn't been available in Germany since a long time<ref>Call to the "Brückenapotheke Roßwein" on March 24, 2011</ref>. An internet search confirmed the impossibility of getting the iodine blocker in Germany as all search results say that the product "is not available at the moment". It seems to be difficult to order it at online pharmacies internationally, too<ref>Search request e.g. http://www.google.de/search?q=Kaliumjodid+Lannacher+kaufen&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:de:official&client=firefox-a#q=Kaliumiodid+Lannacher+kaufen&hl=de&client=firefox-a&hs=C98&rls=org.mozilla:de:official&prmd=ivns&ei=lXSLTae3AoTssgbgguicCg&start=10&sa=N&fp=2233dc865a328f9f as at March 24, 2011</ref>. An exception seems to be [http://goldpharma.com/search/kaliumiodid%20lannacher%2065mg/ Goldpharma] who is still offering the product. This means that independent precaution against radioactive iodine incorporation is impossible in Germany, and people would be totally depending on the authorities' decisions if and when they would assess an accident to be serious and to start to distribute the supplied iodine tablets. The only possibility for people to get the iodine blocker right now is to let a local pharmacy order it from the Austrian producer directly<ref>http://www.lannacher.at/zusatzinfo/1300353565.pdf as at March 24, 2011</ref>. In the United States the iodine blockers had been sold since the very beginning of the catastrophe<ref>Email conversation with a person affected in Hawaii as at March 15, 2011</ref>, while in Russia the price of potassium iodide has raised during five days from $9 to $35<ref name="bellona_russiafareast" />. The “Chicago” pharmacy chain told that it had sold out of all iodine containing medications<ref name="bellona_russiafareast" />. On eBay. tablets of iodine are currently auctioned off for $15 per tablet, with entire packages of the medication going for $2500<ref name="bellona_russiafareast" />. Currently the German radiation protection authority strongly recommends to everyone outside Japan not to take potassium iodide tablets, because the side effects prevail the positive effect of this medicine on too low levels of radioactive iodine as currently appearing<ref name="bfs_jodstellungnahme">http://www.bfs.de/de/kerntechnik/papiere/japan/jodblockade.html as at April 5, 2011</ref>. People in Japan are recommended to follow the instructions of the Japanese authorities or the German embassy<ref name="bfs_jodstellungnahme" />.

Several schools in South Korea closed on April 7, because in some regions traces of radioactive iodine and cesium had been found in rain dropping<ref name="globalsecuritynewswire" />. Southern Korean education officials had sent out an official communication to schools to try to refrain from outdoor activities<ref name="globalsecuritynewswire" />.

=== Rescue activities ===
+
About the reasons for sacrifying as many lifes at the Fukushima NPP by exposing workers, police, military people as well as firefighters to the high radiation levels around the blasted reactors, Dr. Michio Kaku, theoretical physicist, explains: "If it goes to a full-scale evacuation of all personnel, it means that firefighters are no longer putting water onto the cores. That's the only thing preventing a full-scale meltdown at three reactor sites. Once they evacuate, then we past the point of no return. Meltdowns are inevitable at three reactor sites, leading to a tragedy far beyond that of Chernobyl, creating permanent dead zones in Japan."<ref name="naturalnews_ragingmeltdowns" />
+
 
+
As of March 21 military tanks are supposed to support the rescue activities at Fukushima, the Ministry of Defense told to Japanese media. The thick metal armor is thought to protect the soldiers against the dangerous radiation, ''NHK'' reported on March 20. They are supposed to clear up the site to create space for the emergency work.<ref name="spiegel_water" />
+
 
+
Emergency devices were announced to be sent to Japan on March 21 by German atomic facilities including special filters, masks and measuring instruments. ''TEPCO'' had asked for this support; more special equipment has been promised to be sent. The city of Hamburg also announced to provide water containers, cans, blankets and mobile toilets to Japan<ref name="spiegel_water" />.

Meanwhile the operator of the crashed NPPs TEPCO and the Japanese authorities are considering a Chernobyl-like sarcophagus solution as a last means for the damaged reactors<ref name="Spiegel18">http://www.spiegel.de/panorama/0,1518,751682,00.html as at March 18, 2011</ref>. Inventing again and again new ideas to struggle with the nuclear disaster, those responsible are clutching at straws - for instance, they considered covering three reactors with tarp to stop radiation releases to the air<ref name="welt_shimizu" />. This action costing some estimated 80 billion yen (about 653 million EUR<ref>http://finance.yahoo.com/currency-converter/#from=JPY;to=EUR;amt=80000000000as at April 6, 2011</ref>) won't take place before September, the government informed April 5, because the radiation at the plant is too high<ref name="kyodo_sheets">http://english.kyodonews.jp/news/2011/04/83374.html as at April 6, 2011</ref>. ''TEPCOs'' plan to spray synthetic resin using a remote-controlled vehicle<ref name="welt_shimizu">http://www.welt.de/print/die_welt/vermischtes/article13022602/Wo-steckt-Masataka-Shimizu.html?fb_ref=artikelende&fb_source=home_oneline as at April 5, 2011</ref> on the plant premises to fix radioactive particles to the reactor and thus to prevent the further spread of radiation<ref name="abc_radiationspreads" /><ref name="spiegel_riss" /> had to be canceled on March 31 due to bad weather conditions<ref name="japantimes1" />. Besides that, officials at the stricken plant were reported to also plan to cover three badly damaged outer reactor buildings with special fabric caps and fit air filters<ref name="abc_radiationspreads" />. US experts with the ''Nuclear Regulation Commission (NRC)'' recommended to the Japanese rescue management to fill up the reactors with nitrogen to prevent possible new hydrogen explosions inside the containment<ref name="nytimes_array" />. April 6 ''TEPCO'' informed to be preparing the nitrogen injection of 6,000 m³ in a six-day period<ref name="globalsecuritynewswire" /> into the reactor vessel of unit 1<ref name="rponline_nitrogen" /> and possibly later to continue at units 2 and 3<ref name="nytimes_nitrogen">http://www.nytimes.com/2011/04/07/world/asia/07japan.html as at April 6, 2011</ref><ref name="globalsecuritynewswire" /><ref name="faz_onagawa" />. The injection to unit 1 started April 7<ref name="cnn_widen" /> transfering over eight hours roughly 3 % of the proposed amount<ref name="globalsecuritynewswire" />. ''NRC'' also recommended to continue adding boron to the cooling water intending to avoid the reactors to come to criticality again<ref name="nytimes_array" /><ref name="nytimes_nitrogen" />.

ABC News reported on March 31 plans to anchor an empty tanker off unit 2 for pumping huge volumes of radioactive water inside<ref name="abc_radiationspreads" />. Greenpeace also demanded Japan April 5 to catch contaminated water in tankers instead of leading it into the ocean<ref name="faz_greenpeace" />. A huge raft with a big storage capacity for water was already in operation the same day<ref name="faz_greenpeace" />. The '' Los Angeles Times'' reported April 7 ''TEPCO'' to consider bringing in barges and tanks as well as a "megafloat" with a capacity of some 9.5 million liters<ref name="latimes_cleaningup" />. Japan also considers the Russian floating radiation treatment plant Suzuran to be ordered to Fukushima, as confirmed by the Japanese Foreign Ministry on April 7<ref name="latimes_cleaningup" /><ref name="cnn_widen" />. The ship being constructed in Japan to deal the with the old Russian atomic submarines has a capacity of 800 tons for storage and 35 tons for processing radioactive waste<ref name="cnn_widen" />. Between April 11-17 temporary storage tanks of a capacity of 15,000 tons of water are expected to arrive at the nuclear power plant, ''TEPCO'' said<ref name="cnn_widen" />. April 14, ''TEPCO'' completed the installation of makeshift tanks at the NPP containing up to 1000 tons of water<ref name="nhk_2011_04_11" />. By the end of May, ''TEPCO'' wants to hold 27-thousand tons of wastewater in additional tanks<ref name="nhk_2011_04_11" />.

+
Prime minister Kan was reproached to have disturbed TEPCOs rescue activities as the operator couldn't let off pressure from unit 1 due to him flying there on March 12<ref name="ntv_reproached">http://www.n-tv.de/ as at March 29, 2011</ref>. After his departured the reactor exploded<ref name="ntv_reproached" />.

+
About two weeks after the tsunami and the explosions of several nuclear reactors, Japan now asked for support of US-American, French and Russian experts<ref name="spiegel_dimension" />. A Marine unit specialized in emergency nuclear response has been ordered by the US military to deploy in Japan assisting local authorities<ref name="presstv_china" />. Three unmanned aerial vehicles are expected to send from France for surveillancing radiation and heat levels as well as other activity, ''Kyodo'' reported April 6<ref name="globalsecuritynewswire" />. ''TEPCO'' announced April 9 to send an unmanned drone "T-Hawk", developed by the US conglomerate ''Honeywell'', over units 1-4 to help assessing the extend of damages<ref name="yahoo_minister" />.
+
 
+
Due to the high level radioactive contamination, rescue activities to search for victims of the earthqakes and tsunami won't take place in an area of 30 kilometers around the wrecken NPP, reported ''Kyodo'' about two weeks after the disaster, although some 1,000 bodies are suspected there<ref name="spiegel_schlampt" /><ref name="gmx_sterben" />.
+
 
+
To make room in storage containers for the increasing amounts of far more radioactive runoff water<ref name="rponline_nitrogen" /> (10,000 times the legal limit), ''TEPCO'' intentionally started April 4 to flush<ref name="spiegel_fish" /> thousands of ons of less radioactive water (100 times the legal limit<ref name="aljazeera_nosafelevels" />; other source: 500 times the legal limit<ref name="cnn_expert" />) into the Pacific<ref name="nytimes_nitrogen" /><ref name="kyodo_flushing">http://english.kyodonews.jp/news/2011/04/83353.html as at April 6, 2011</ref>. Thus, some 11,500 tons of contaminated water will be flushed to the ocean<ref name="latimes_success" /><ref name="rponline_nitrogen" /><ref name="aljazeera_nosafelevels" />. By April 5 they had released less than 25 % of the proposed amount<ref name="latimes_success" />, while by April 7 they flushed more than 56 million liters to the sea<ref name="latimes_cleaningup">http://www.latimes.com/news/nationworld/world/la-fg-japan-water-20110407,0,2011011.story as at April 8, 2011</ref>. According to the Japanese government this operation will probably be continued until Friday April 8<ref name="voanews_newrisk" />. Several neighbouring countries protested against this measure intentionally polluting the common ocean with additional radioactivity<ref name="rponline_nitrogen" /><ref name="voanews_newrisk" />, what was returned by Japan's chief Secretary Edano saying these releases would "not cause immediate radioactive contamination in neighboring countries". <ref name="kyodo_flushing" />. However, Edano apologized to them not having informed them earlier about the plans to pump radioactive water to the sea<ref name="voanews_newrisk" />.

=== Causes Of The Disaster ===
+
<span style="font-weight:bold; font-style:italic">What happened in detail in Fukushima is yet unclear as the authorities and the operator publish hardly any concrete information, and probably by now no one knows exactly how the reactors look inside to examine the happenings before the explosions occured. However, there are hypotheses about the causes of the accident. The major interpretation reads as following:</span>
+
 
+
When the 9.0-magnitudes earthquake occured on March 11 5.46 AM UTC<ref name="wiki_quake">http://en.wikipedia.org/w/index.php?title=2011_T%C5%8Dhoku_earthquake_and_tsunami&oldid=420466410 as at March 24, 2011</ref>, the units 1-3 of Fukushima I ''Daiichi'' were shut-down automatically<ref name="wiki_quake" />, while the reactors 4-6 were already offline due to regular maintenance<ref name="nisa_april4" />. This earthquake was the most powerful known one ever to have hit Japan, and one of the five most powerful earthquakes in the world overall since modern record-keeping began in 1900<ref name="wiki_quake" />. More than 600 aftershocks of magnitude 4.5 or greater occurred since the initial quake<ref name="wiki_quake" />. The earthquakes also disconnected the NPPs from the grid making emergency generating necessary to supply the colling systems<ref>http://www.ustream.tv/channel/nhk-world-tv as at March 24, 2011</ref>. The earthquakes also caused the huge tsunami reaching 14-15 meters<ref name="cnn_tsunami" /><ref name="wiki_quake" /><ref name="spiegel_dimension" /><ref name="bellona_russiafareast" />. The tsunami surmounted the 5 meter protection seawalls that were thought to stop normal tsunamis, engulfed the facilities and thus knocked out the units' emergency power generators and pumps<ref name="cnn_tsunami" /><ref name="wiki_quake" />. Although the Tsunami is regarded to have been high, it has not been the highest Tsunami hitting Japan in history - 22 Tsunamis have been recorded since 684 AD, including 11 events with waves heights in the range of 13-55 m<ref name="wiki_quake" />. The emergency power generators still worked for a certain time before they failed. When the cooling systems stopped working hydrogen was generated under the conditions of hot steam and high pressure. Ken Morita, a spokesman for the Nuclear and Industrial Safety Agency explained in an interview in the beginning of April that the fuel rods were exposed due to the lack of water and heated up, leading the zirconium of the rods to react with water forming hydrogen<ref name="nytimes_nitrogen" />. Because of the nitrogen concentration in the reactor core it could not ignite inside the containment. To reduce the pressure and to prevent an explosion the operator opened the containment to release some steam (and simultaneous to release radiation to the environment). Shortly afterwards unit 1 exploded due to the hydrogen catching fire in the nitrogen poor reactor building. This happened in other units later, too.

+
Even after shutting down a reactor a high amount of so-called decay-heat is produced by the radioactive inventory<ref>http://en.wikipedia.org/w/index.php?title=Decay_heat&printable=yes as at March 24, 2011</ref><ref name="mit_decay">http://mitnse.com/2011/03/16/what-is-decay-heat/ as at March 30, 2011</ref>. The decay products of the [[Nuclear fission|nuclear fission]] keep on decaying producing heat: Immediately after the shut down depending on the time of usage of the fuel in the reactor the decay heat is 5-10 % of the original thermal output of the reactor. For instance, a current reactor has an electric output of 1,300 MW and some 4,000 MW thermal output - thus, the decay heat at the moment after the shut down is still 200-400 MW. This amount first decreases fast and later slower - after 10 seconds it is 149 MW, after 1 minute it is 102 MW, after 1 hour it is 40 MW, after 1 day it is 18 MW. After 3 months it is still 2 MW. This heat needs to be lead away to prevent a meltdown of the fuel. As the heat and pressure would not be high enough for the operation of the steam turbine, the fuel needs to artificially be cooled. Because of the small volume in the reactor core and the produced heat a meltdown would cover the entire fuel inventory. Locally reduced meltdowns only appear in connection to material defects, but not as a result of a loss of coolant. Even months after shutting down the reactor the produced decay heat is high enough to cause a meltdown if the cooling systems don't work.<ref name="wikipedia_nachzerfall">http://de.wikipedia.org/w/index.php?title=Nachzerfallsw%C3%A4rme&oldid=87026071 as at March 29, 2011</ref>

+
Three weeks after the tsunami, on April 1, unit 1 will still produce 5.2 MW decay heat, while units 2 and 3 will produce 8.8 MW each due to their higher capacities, students of ''Nuclear Science and Engineering''<ref>http://web.mit.edu/nse/index.html as at March 30, 2011</ref> at the ''Massachusetts Institute of Technology (MIT)''published on their [http://mitnse.com Fukushima blog]<ref name="mit_decay" />. This heat needs to be cooled down to avoid a more severe accident: "If the decay heat is not removed then the reactor fuel begins to heat up and undesirable consequences begin as the temperature rises such as rapid oxidation of the zircaloy cladding (~1200C), melting of the cladding (~1850C), and then the fuel (~2400-2860C)"<ref name="mit_decay" />. The reactors and cooling ponds will take years to cool, says Hiroto Sakashita, a nuclear reactor thermal hydraulics professor at the Hokkaido University<ref name="abc_radiationspreads" />.

+
On March 20, ''[http://www.nuclearpowerdaily.com/reports/Days_before_quake_plant_operator_admitted_oversight_999.html Nuclear Power Daily]'' uncovered TEPCO to have lied about their safety procedures: "We can't say that the lapses listed in the (February 28) report did not have an influence on the chain of events leading to this crisis", a nuclear safety agency official said. TEPCO had admitted a couple of days before the catastrophe that they had faked reparing records. For several years wrong statements about inspections and results had been made by TEPCO including parts of cooling systems like water pump motors and diesel generators.<ref>http://www.nuclearpowerdaily.com/reports/Days_before_quake_plant_operator_admitted_oversight_999.html as at March 21, 2011</ref>

Another message about the design based failure of the emergency cooling systems in Fukushima arose by film maker Adam Curtis producing the documentary "A Is For Atom". He pointed out that his interviews from the 1960's already showed a design failure of the cooling systems of General Electrics ''Boiling Water Reactors'' of the Fukushima type. A couple of years later in 1971 the Atomic Energy Commision tested them in reality and realized that while the systems basically worked properly the level of water in the core did not rise. "We discovered that our theoretical calculations didn't have a strong correlation with reality. But we just couldn't admit to the public that all these safety systems we told you about might not do any good", one of the AEC scientists says in the film. In the same year the first of the Fukushima reactors came online.<ref>http://www.bbc.co.uk/blogs/adamcurtis/2011/03/a_is_for_atom.html as at March 23, 2011</ref> Units 1, 2 and 6 of Fukushima I Daiichi had been supplied by General Electrics<ref>http://www.anti-atom-piraten.de/2011/03/seit-1971-versagen-des-notkuhlsystems-beim-reaktortyp-fukushima-als-designfehler-bekannt/ as at March 23, 2011</ref>.

<span style="color:green">In a report of June 16, 2011, the IAEA concludes that a number of safety requirements had not been met in advance to the nuclear catastrophe in Fukusima, and that also the Japanese authorities failed from certain perspectives. It also designates some "lessons" learned by this disaster, which - actually - just prove that it is practically impossible to operate atomic power plants in a safe way.<ref>http://www.guardian.co.uk/environment/damian-carrington-blog/2011/jun/20/nuclearpower-nuclear-waste as at June 21, 2011</ref></span>

=== Reactions in other countries ===
+
IPPNW, the ''International Physicians for the Prevention of Nuclear War'', on March 22 demanded the ''World Health Organization'' (WHO) to inform the Japanese public about the true impacts of the Fukushima disaster. A treaty between WHO and IAEA from 1959 forces the World Health Organization to assign their competences on health impacts of radiation to them. But the objective of the IAEA actually is the promotion of nuclear power. There is a conflict of interests between the protection of people against nuclear power and fostering this technology. "The WHO should declare themselves in favor of the evacuation of the women, infants and pregnant women of the affected regions as they are particularly radiation sensitive", IPPNW physician Dr. Angelika Claußen explained.<ref>http://www.ippnw.de/startseite/artikel/0f63d4ab40/who-soll-objektiv-ueber-gesundheitli.html as at March 24, 2011</ref><ref>http://www.dw-world.de/dw/article/0,,14941784,00.html as at March 26, 2011</ref>
+
 
+
<span style="color:green">The ''International Atomic Energy Agency (IAEA)'' demanded in reaction to the disaster in Fukushima to get more authority to set international standards for the safety of atomic power plants and to receive the power to controll and enforce these regulations. Some countries, particularly Japan, refuse to accept interferences to their nuclear policies by an international authority.<ref>http://www.spiegel.de/wissenschaft/technik/0,1518,769351,00.html as at June 21, 2011</ref></span>

In the USA the sites of supposed new NPPs will be examined, Minister of Energy Steven Chu told ''Fox News'' on March 20<ref name="spiegel_water" />. Additionally also some running reactors should be reviewed regarding the continuation of operation<ref name="spiegel_water" />. US president Obama had ordered the examination of the US-American NPPs<ref name="dw_obama">http://www.dw-world.de/dw/article/0,,14956873,00.html as at April 5, 2011</ref> on March 17, while he refused to question the technology in general<ref name="spiegel_water" />. In a speech of March 30, Obama announced to continue plans of construction of new nuclear power plants in the United States<ref name="dw_obama" />. Also the United Arab Emirates announced to review their plans for the construction of a first nuclear power plant in their country<ref name="spiegel_water" />.

While experts yet discuss the impacts of the nuclear catastrophe, the German atomic lobbying organization "Deutsches Atomforum" insisted a similar accident could not happen at German nuclear power plants as their safety systems would be prepared to deal with those situations (the same the Japanese nuclear industry said about their reactors by now)<ref>http://www.kernenergie.de/kernenergie/documentpool/Presse/PM-2011-04_Ereignisse_Japan.pdf as at March 12, 2011</ref>.

Under public pressure and on view of several elections during the next weeks the German government decided a couple of days after the first explosion at the Fukushima NPP to temporary shut-down seven German NPPs for some 3 months<ref name="contratom_consequencies">http://www.contratom.de/2.0/index.php?mod=blog&artikel=1820 as at March 17, 2011</ref><ref name="Spiegel_Atomwende">http://www.spiegel.de/politik/deutschland/0,1518,751078,00.html as at March 21, 2011</ref>, concerning the oldest and most dangerous nuclear reactors: Neckarwestheim-1, Philippsburg-1, Isar-1, Biblis-A, Unterweser, Biblis-B, Krümmel and Brunsbüttel have been shut-down now<ref>http://www.contratom.de/2011/03/17/sofort-abschalten/ as at March 21, 2011</ref>.

Basically all German NPP will be subject of safety checks during the next months, the government decided<ref>http://www.spiegel.de/video/video-1115491.html as at March 21</ref>. In contrast to this decision Chancellor had stated in direct reaction to the catastrophe in Japan that the German reactors would be safe and that there wouldn't be any reason for concerns.

A [https://www.x-tausendmalquer.de/index.php?id=93 blockade of nuclear power plants] has been announced by ''[https://www.x-tausendmalquer.de/ X-tausend mal quer]'' for June - when the moratorium of the seven oldest reactors in Germany (they have been tuned off for three months after Fukushima) will end. People are already publicly announcing [https://www.x-tausendmalquer.de/index.php?id=96 their participation] in theses sit-in blockades or [https://www.x-tausendmalquer.de/index.php?id=97 their solidarity with the action]. Demonstrations are announced in 13 decentral demonstrations at German atomic plants on April 25<ref>http://tschernobyl25.de/ as at March 28, 2011</ref> in memorial of the Chernobyl disaster 25 years ago.

Scientists are calling out for a nuclear phase-out gathering colleagues to support the appeal<ref name="wissenschaftler">http://www.wissenschaft-fuer-atomausstieg.de/ as at April 7, 2011</ref>. By April 7, more than 500 scientists signed the call-out<ref name="wissenschaftler" />. Unexpectedly the German ''BDEW'' an association of the electricity industry with members like nuclear companies EON and RWE demanded for a nuclear phase-out possibly by 2020, but at the latest by 2023, getting criticism by the atomic industry for that stance<ref>http://www.spiegel.de/wirtschaft/soziales/0,1518,756032,00.html as at April 9, 2011</ref>.

Detection of iodine-131 and xenon-133 from Fukushima up to March 29 - image provided by BfS

As a result of a 14 meter tsunami wave[1][2] and a 9.0-magnitudes earthquake the Fukushima I Daiichi[3] atomic power plant in Japan experienced a nuclear catastrophe of a level higher than the 1979 Harrisburg accident, maybe turning out to become even worse than the 1986 Chernobyl catastrophe[4][5][6][7][8][9][10][11] including several explosions, fires, failing cooling systems,[12] meltdown of fuel elements and uncontrolled releases of high amounts of radioactivity[9] since March 11, 2011. Unit 1 exploded on March 12, 2011 at 6.36 AM UTC[13][14], unit 3 exploded two days later on March 14 at 2.01 AM UTC[15][16][17] and eventually also unit 2 blasted in the following night (14/3/11 9.10 PM UTC) damaging the reactor core and as officially confirmed releasing serious amounts of radiation[18][19]. Also unit 4 which had all nuclear fuel in the reactors spent fuel pool exploded March 14 at approximately 9 PM UTC[20].

Another 6.5 earthquake occured on March 28 160 kilometers from Fukushima I Daiichi[21]. An even stronger quake at 7.1 having its epicenter in distance of 120 kilometers to the Fukushima NPP took place April 7 causing the emergency workers at Fukushima I Daiichi again to be evacuated from the site, while two of three emergency power systems failed due to the aftershock at the Onagawa NPP[22][23]. A nuclear meltdown occured in unit 2[24], the Japanese government ended up to admit on March 28[25] - "The battle to save the four crippled reactors is lost", Japanese officials conceded March 31[24]. Operator TEPCO informed not to be able to guarantee preventing another meltdown[21]. The IAEA informed on March 31 about a possibility of a "recriticality" at the Fukushima plant, which means a nuclear chain reaction would resume leading to more radiation releases, although the reactors were automatically shut down on March 11 due to the quake[12]. April 12 NISA classified the Fukushima disaster to INES level 7[5][4].


"Fukushima means 'fortunate island' but the region's luck melted down along with the reactors at the Fukushima Daiichi nuclear plant following the earthquake and tsunami."[26]

The atomic disaster in Fukushima has been classified an INES 7 accident by the Japanese Nuclear and Industrial Safety Agency (NISA) as demanded by Greenpeace and experts already long time before. Japan declared an "atomic power emergency" on March 11. Thousands of residents have been evacuated from the 20 kilometer zone around the stricken nuclear power plant. The disaster was caused by an interaction of a heavy earthquake of magnitude 9 destroying supplies and parts of buildings and a tsunami wave about 14 meters high destroying the emergency power generators. The emergency power batteries bridged a couple of hours, before the cooling systems failed totally. Exposed without any or enough water the fuel rods of one or more reactors melted down at up to 2,700 degrees.

As a result of the earthquake and the explosions in four reactors of the nuclear Daiichi complex several reactors' containment was damaged. A particular threat in this catastrophe is unit 3 of the NPP, a MOX fueled reactor containing large amounts of plutonium which is of special health risk due to its high energy radiation as a substantial alpha emitter and due to its specific toxic characteristics as well as because of its long-term halftime of more than 24,000 years.

New threats of catastrophic extend at the Daiichi units are uncovered every few days - often by foreign experts, while Japanese authorities and the operator of the blasted reactors yet downplay the impacts of the catastrophe and in many cases would not concede the incidents before being published by other hand. By April 9, some of these possible threats uncovered by a US newspaper are: a collapse of containment structures due to the weight of tons of water poured for cooling onto the reactors; a molten core could melt through the bottom of the pressure vessel; a new hydrogen explosion destroying the containment and releasing large amounts of high radioactive substances; increased risks caused by seawater that had been used in the emergency cooling operations.

A fire occured close to block 4 on April 4 and was quickly extinguished after it had been recognized.

INES Catastrophe Level Dispute

Since April 12, the Fukushima disaster is classified at INES level 7 by the Japanese Nuclear and Industrial Safety Agency (NISA)[5] - the highest possible catastrophe classification of the IAEA[4][27]. Until this day both NISA and the International Atomic Energy Agency (IAEA) had refused to raise the INES level from 5 to the highest possible category, while since March 25 Greenpeace demanded the IAEA to classify Fukushima as an INES level 7 accident like Chernobyl 1986 based on a study[28] they had published[29]. Several other nations' radiation protection authorities had already classified it to level 6[30]. Japan was reported on March 31 to be considering to increase the accident level to INES 6[9].

Atomic Power Emergency Declared

An atomic power emergency had been declared by the Japanese government on March 11[1], while up to 300,000 residents (other sources talk about "over 200,000"[31][32] or 77,000 [33]) had been evacuated in a zone of 20 kilometers around Fukushima I Daiichi and Fukushima II Daini[3][18]. Several emergency power generators failed supplying the emergency cooling systems with electricity[30]. The authorities confirmed the release of radioactive elements such as cesium and iodine[34]. Also a fire occured on March 15 at 0.40 AM UTC at unit 4[19] - a reactor unit that had not even been in operation when the tsunami hit the Japanese coast on March 11.

Hidehiko Nishiyama, spokesman with NISA explained April 3: "It would take a few months until we finally get things under control and have a better idea about the future. - We'll face a crucial turning point within the next few months, but that is not the end."[6].

Nuclear Meltdowns Conceded

Independent experts say that a nuclear meltdown must have happened[35][36][37]. "The cores of the three reactors[38] are believed to have partially melted", the Japanese news agency Kyodo reported on March 14[19][39]. According to the German news "Tagesschau" Japanese officials also confirmed a nuclear meltdown in Fukushima[35]. This had been confirmed by a statement of Chief Secretary Yukio Edano on Sunday saying that at least one nuclear meltdown occured [30], eventually confirmed by the Japanese government on March 28: a nuclear meltdown of fuel elements - maybe melting through the bottom of its containment vessel and on to a concrete floor[40][24] - happened at unit 2[24] already shortly after the earthquake and tsunami of March 11[41]. Japanese officials called it a "partial meltdown"[42]. This seems not to be correct due to the limited volume and high temperatures in the core[43] as explained in section Causes Of The Disaster. The operator had indicated already March 15 that a meltdown could have happened as the fuel rods had been damaged[19]. GE's head of safety research for this type of reactor told The Guardian newspaper he would believe the reactor core of unit 2 to already have melted through the bottom of the pressure vessel and at least some of it would have reached the concrete floor beneath[12].

Earlier Edano had stated also a nuclear meltdown in reactor 3 of Fukushima 1 to be "possible"[30]. This was again topic of concern on March 26, while scientist Sebastian Pflugbeil suspects the meltdown to happen already for several days due to the high releases of radiation[44]. Meanwhile (31/3/11) we have to talk about "three raging meltdowns in progress"[9]. Japan’s Nuclear and Industrial Safety Agency (NISA) said on March 12 that the explosion at the Fukushima Daiichi No. 1 nuclear plant could only have been caused by a meltdown of the reactor core[45]. Nuclear engineer Arnold Gundersen, who worked for years in leading position for the atomic industry, on April 7 said in a broadcasting a nuclear meltdown in the spent fuel ponds at unit 4 is going[46]. The fuel is totally exposed to the air, while it should be covered by five meters of water, he explained[46]. According to an internal Areva paper on Fukushima, on fresh air a core meltdown would occur, leading to a large release of radiation due to a lack of retention of fission products[46].

In an interview published April 2, Greenpeace expert Wolfgang Sadik expressed concerns about the officials searching for zirconium outside the reactors - which actually means: they are looking for traces of the melted reactor core[47].

An internal Areva paper on the Fukushima disaster reported meltdowns at temperatures up to 2,700 degrees[46].

The hydrogen building up in several units (especially unit 1) is a symptom of damaged fuel rods in the cores of the reactors[2].

Unit 2 is believed to have gone back into criticality with a nuclear chain reaction coming and going[6]. "Since unit two is showing signs of fission happening, the chances of something more catastrophic happening at that site are increasing," Mary Olson, director of the Southeast Office of the Nuclear Information and Resource Service (NIRS) explained in an interview on April 8[6].

Extension Of The Evacuation Zone

First, an area of 3 kilometers had been evacuated on Friday, March 11. Later it was enlarged to a 10 km evacuation zone and then to 20 km, while residents of the 20-30 km zone were advized not to leave their houses[48][49][1]. On the very first day a BBC reporter spoke about a prohibition zone of 60 kilometers.[50] March 25, Japan's government urged the residents of the 20-30 km zone to leave the area, too[51][52][53][24]. More than 10,000 people are still in the area, NHK reported[54] Japan's government considers to recommend residents outside the 30 kilometer zone to le
