According to Kawata, soil in a 600 square kilometer area mostly to the northwest of the Fukushima plant is likely to have absorbed radioactive cesium of over 1.48 million becquerels per square meter, the yardstick for compulsory migration orders in the 1986 Chernobyl catastrophe.
Kawata also said soil in a 700 square km area is likely to have absorbed 555,000-1.48 million becquerels per square meter, which was a criteria for temporary migration during the Chernobyl disaster.
Kawata estimated the soil contamination using data on radiation levels in the air monitored by the Ministry of Education, Culture, Sports, Science and Technology.
The size of the contaminated areas in the Fukushima crisis is one-tenth to one-fifth of those polluted in the Chernobyl disaster, Kawata said.

On Sunday, Tokyo Electric Power Company began measuring the density of radioactive elements above the No.1 and No.4 reactors.
The firm used instruments attached to the crane pumps that are injecting water into the reactors.
TEPCO detected 360 becquerels of cesium-134 per cubic meter above the No.1 reactor, where most of the fuel rods are believed to have melted. The amount is 18 times the allowable limit for the plant's perimeter.
The firm also discovered 7.5 times the limit of cesium-134 above the No.4 reactor, which has no fuel in its core. The substance is believed to have come from the fuel storage pool and the neighboring No.3 reactor.
TEPCO says it will measure the levels of radioactive elements above the No.2 and No.3 reactors. It also plans to cover the reactor buildings with polyester sheets to prevent the further dispersal of radioactive materials into the air.

France's Institute for Radiological Protection and Nuclear Safety (IRSN)
highlighted an area northwest of the plant that lies beyond the 20-km (12 mile) zone whose inhabitants have already been evacuated.
Radioactivity levels in this area range from several hundred becquerels per square metre to thousands or even several million bequerels per square metre, the IRSN report, issued late Monday, said.
Around 70,000 people, including 9,500 children aged up to 14, live in the area, "the most contaminated territory outside the evacuation zone," the agency said....
The IRSN report is based on data for radioactivity reported by the Japanese authorities and from US overflights of the zone.
Eine neue Schnellzugverbindung wurde am 12. März auf Japans Südinsel eröffnet und zur Feier des Tages ein aufwendiges Werbevideo mit Tausenden von tanzenden Japanern entlang der Strecke gedreht:

Am Tag vor der Eröffnung der Strecke aber bebte bekanntlich die Erde, das Werbefilmchen wurde nicht gezeigt. Jetzt ist es raus und wurde zum Hit: Fröhliche Musik und die gemeinsame Choreografie der vielen Beteiligten scheinen Hoffnung und ein Licht am Ende des Tunnels zu symbolisieren. Irgendwie unwiderstehlich.

The Tokyo Electric Power Company, known as TEPCO, told reporters Thursday that nearly 60 tons of radioactive water may have spilled out, raising further concerns about the utility's ability to handle the worst nuclear crises since Chernobyl.
The latest leak was discovered amid efforts to transfer highly contaminated water from the number 2 and number 3 reactors to an improvised storage facility. TEPCO says the water level in the facility had dropped nearly two inches in just 20 hours, suggesting a leak.

At a press conference Thursday, Chief Cabinet Secretary Yukio Edano denied accusations of a "cover-up," but admitted the government needed to take seriously "the criticism that we haven't done enough to provide and circulate information."
...
Analysis by laboratories in France and Belgium found high levels of radioactive iodine and radioactive cesium in seafood, according to Greenpeace. Contamination levels were highest in seaweed samples, which contained radiation 50 times higher than official limits.
"Our data shows that significant amounts of contamination continue to spread over great distances from the Fukushima nuclear plant," said Greenpeace Radiation Expert Jan Van Putte. "Radioactive hazards are not decreasing through dilution or dispersion, but the radioactivity is instead accumulating in marine life."

Sauerei, nur: Zur radioaktiven Belastung von Mensch und Umwelt wäre es doch genauso gekommen, wenn Tepco von vornherein von einer Kernschmelze gesprochen hätte? Die verdienen Prügel, keine Frage, aber der Vorwurf oben ist etwas überzogen.

Press release of May 26th, 2011
TEPCO’s deceit – The lessons from Fukushima
Greenpeace publishes report on Japanese meltdown
Hamburg, 26. 5. 2011 – Greenpeace today presents a previously unreleased study
which unmasks the policy of disinformation of the nuclear group TEPCO and of the
Japanese and international atomic agencies as being dangerous and irresponsible. It
was already a few hours after the Japanese earthquake of March 11 that TEPCO knew
of the core meltdowns at Fukushima and that it accepted the radioactive pollution of its
employees, of the surrounding region and of the ocean water. The misleading
descriptions of TEPCO were uncritically repeated also by the German Gesellschaft für
Anlagen- und Reaktorsicherheit (GRS) (Nuclear Safety Agency). The environmentalists
are of the opinion that the new findings also have consequences for the technical and
ethical assessment of atomic energy in Germany. Greenpeace therefore today hands
over this study to the ethics commission which will present its recommendations to the
federal government on Saturday.
“No-one would lie without a reason“, says Shaun Burnie, a Greenpeace nuclear expert.
“The elusions and concealments of TEPCO and the continuous declarations of the
International Atomic Energy Agency all serve only one purpose: They want the people to
believe that atomic energy is controllable even after the catastrophic disaster at
Fukushima. But this is a dangerous illusion.“
The GP commissioned study makes clear that TEPCO must have known of the core
meltdowns already in the early hours after the earthquake and that it has knowingly
deceived the Japanese public and the international community since then. Within the
first 24 hours after the accident TEPCO had direct access to data that made clear that
temperatures in the pressure vessel were increasing rapidly and that a core meltdown
was imminent. According to British nuclear engineer Dr. John Large, within days of the
explosions of Fukushima-daiichi reactor 1 and 3 significant core meltdown was clear in
contrast to the communication of TEPCO and the IAEA. The decision to pour sea water
on the reactors was made knowing perfectly well that the pressure vessel was already
broken. They accepted that many tens of thousands tons of highly radioactive water
could risk drain and escape into the environment.
“Germany is not prepared for a worst case. The helplessness in dealing with the
disaster in Japan makes this all too clear“, says Burnie. “The measures taken in Japan
to cool down the reactors would be impossible in Germany. We could not pump
radioactive water into the sea. German disaster control would not be able to cope with
an evacuation. There are then only three logical conclusions for Mr. Töpfer and the
Ethics Commission: The most dangerous reactors must be shut down immediately, the
facilities situated in areas prone to earthquakes must be re-evaluated, without any
taboos, and all other nuclear power plants must be shut down as quick as possible,
without any loopholes. A mid-term withdrawal from nuclear energy in 2022 would not
be responsible and therefore is not acceptable“.
The team, led by Michael Weightman [csmonitor.com], Britain [csmonitor.com]’s chief nuclear safety inspector, expects to find answers to what one Japanese official described as a “long list of questions.”
But the aim of the visit was not to apportion blame, stressed Mr. Weightman: “We will come to our best judgment without fear or favour from anybody,” he said, adding that the purpose of the visit was to “seek information to see how the world can learn lessons from the unfortunate events here.”
He added: “We have full cooperation and access to information. Whatever questions we ask, there are answers. We will come to our own views on information we seek. We seek to learn lessons on behalf of the world.”
...
Japan’s top government spokesman, Yukio Edano [csmonitor.com] said: ''The IAEA team's visit to investigate the accident is important from the standpoint of ensuring transparency to get to the bottom of this accident.”
The operator, Tokyo Electric Power [csmonitor.com] [Tepco], did little to further its faltering reputation on Thursday, when it altered its account of its initial response to the nuclear accident.
The firm said it had continued to inject seawater into one of the damaged reactors soon after the March 11 tsunami, reversing an earlier statement in which it said it had suspended the risky measure amid pressure from the prime minister’s office.
siehte da biste schon viel näher dran als mit dem Einzelkämpfer Hans Gross.
IAEA und nationale Zentren (wie CEA) oder Industrie (zB Westinghouse oder Areva) arbeiten und anlysieren doch schon seit Wochen. Und zwar alles - Unfallszenarien, Sicherheit:
Was geschah ? Was hat Tepco gemacht ? Was hätten sie besser machen können ...
Warum ist übrigens bei Fukushima Dai-ni nichts passiert ? [ja die Frage passt nicht in dieses Forum, da gab"s ja kein Unglück].
Innerhalb der ersten 24 Stunden des Unfalls habe Tepco direkten Zugang zu Daten gehabt, welche die rasch ansteigenden Temperaturen im Druckbehälter sowie eine Kernschmelze offensichtlich gemacht hätten, heißt es in der Studie des britischen Ingenieurs John Large.
