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.
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 ...
[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]
Three people died, one man got radiation sickness and went blind. [62] 15 October 1958: Vinča, Yugoslavia. There was a criticality incident in a newly installed reactor. Six young researchers received high doses of radiation, and were subsequently treated at "Kiri" institute in Paris where one of them died. [citation needed]
TEPCO needs to find and repair the damaged parts of the reactor to recover melted nuclear fuel before TEPCO can begin the process of decommissioning the reactor. However high radiation often stops workers from entering the building. This scenario means it will take a long time to find the problems in the containment vessel. [62]
Fukushima helped push BHP Billiton to pour its money into copper, iron ore, metallurgical coal, and hydrocarbons. Overall, BHP Billiton's uranium divestments are understandable.
In October 2011 the Japanese ministry of Science launched a telephone hotline to deal with public concerns about radiation exposure in areas outside Fukushima Prefecture. Concerned Japanese citizens had taken up a new hobby: walking with Geiger-counters through their city or village in search for all places with raised radiation levels.
The plant with seven units is the largest single nuclear power station in the world, which now again is shut down due to the Fukushima accident. [46] 0: 1 Dec 2009: Hamaoka, Japan: Leakage accident of radioactive water. 34 workers were exposed to radiation: 0: Mar 2011: Fukushima Dai-ichi, Japan: The world's second INES 7 accident.
