Normal radiation dose rates at the Fukushima I site as established by the stream of monitoring post readings in the 3 months preceding the accident. (03/01=1 March 2011, 1 Gray= 1 Sv for gamma radiation) [98] Radiation fluctuated widely on the site after the tsunami and often correlated to fires and explosions on site.
[3] 0.3 TBq is equal to 1 / 40 th of the natural radiation in one km 3 of seawater and 1 / 50000000000 th of the total natural radioactivity in the oceans. [4] Following the Fukushima I accidents, The Economist reported that the International Energy Agency halved its estimate of additional nuclear generating capacity to be built by 2035. [5]
The first of the typhoons of the season is due to strike the area, while Japan states radiation levels at the seabed are several hundreds of times above normal levels off the coast of Fukushima. "The Science Ministry announced late on Friday highly radioactive materials were detected in a 300-km north-south stretch from Kesennuma in Miyagi ...
Reuters was recently given exclusive access to Japan's Fukushima nuclear plant, where three reactors melted down in 2011 after a powerful earthquake and tsunami overwhelmed the seaside facility.
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 ...
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).
Prior to Fukushima, the Chernobyl disaster was the only level 7 accident on record, while the Three Mile Island accident was a level 5 accident. Arnold Gundersen, an engineer frequently commissioned by anti-nuclear groups, said that "Fukushima is the biggest industrial catastrophe in the history of mankind".
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.
