The radiation effects from the Fukushima Daiichi nuclear disaster are the observed and predicted effects as a result of the release of radioactive isotopes from the Fukushima Daiichii Nuclear Power Plant following the 2011 Tōhoku 9.0 magnitude earthquake and tsunami (Great East Japan Earthquake and the resultant tsunami).
Fukushima I and II Nuclear Accidents Overview Map showing evacuation and other zone progression and selected radiation levels. The Japanese reaction occurred after the Fukushima Daiichi nuclear disaster, following the 2011 Tōhoku earthquake and tsunami. A nuclear emergency was declared by the government of Japan on 11 March.
TEPCO claimed no significant change in radiation levels, and the smoke subsided later the same day. [40] On 23 March, black smoke billowed from Unit 3, prompting another evacuation of workers from the plant, though Tokyo Electric Power Co. officials said there had been no corresponding spike in radiation at the plant.
The 9.0 magnitude quake and tsunami that ravaged parts of Japan’s northeastern coast on March 11, 2011 killed about 20,000 people and drove thousands from their homes in the prefectures of ...
The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan which began on 11 March 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami , which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy ...
In December 2011, as Japan completed "step 2" of its control roadmap at Fukushima, U.S. NRC chairman Jaczko visited the plant and said afterwards "that there was no longer enough energy in the reactors at the crippled Fukushima No. 1 Nuclear Power Plant to produce an offsite release of radiation, but pointed out that a large cleanup task remained".
No radiation-related deaths or acute diseases have been observed among the workers and general public exposed to radiation from the accident (Chapter II A(b) paragraph 38). Adults living in the city of Fukushima were estimated to have received, on average, an effective dose of about 4 mSv (Chapter II A(a) paragraph 30).
An official in charge of the wrecked Fukushima nuclear power plant says the upcoming release of treated radioactive water into the sea more than 12 years after the reactors' meltdown marks “a ...
