The 2011 Fukushima Daiichi nuclear disaster, the worst nuclear incident in 25 years, displaced 50,000 households after radioactive material leaked into the air, soil and sea. [1] Radiation checks led to bans on some shipments of vegetables and fish. [2] Map of contaminated areas around the plant (22 March – 3 April).
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 ...
Studies done after nuclear accidents in the past suggested that radiation levels of more than 100 millisieverts at once would have negative effects on human health, but negative effects from lower levels were never found. The Japanese government hoped to be able to accept 20 millisieverts per year as below the limit harmful to human health.
In Futaba, the hardest-hit town and a co-host of the Fukushima Daiichi plant, a small area was opened in 2022. About 100 people, or 1.5% percent of the pre-disaster population, have returned to live.
Highly radioactive water leaked from a treatment machine at the tsunami-hit Fukushima Daiichi nuclear power plant, but no one was injured and radiation monitoring shows no impact to the outside ...
And at a ceremony in Fukushima prefecture, where some 20,000 people still cannot return to their homes because of radiation, Gov. Masao Uchibori vowed that rebuilding will continue as the decades ...
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).
The long-term detrimental effects on agriculture, farming, and livestock, can potentially affect human health and safety long after the actual event. After the Fukushima Daiichi accident in 2011, surrounding agricultural areas were contaminated with more than 100,000 MBq km −2 in cesium concentrations. [154]
