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 University of Hiroshima University did establish a leading research center into the effects of radiation on the human body and health: the Research Institute for Radiation, Biology and Medicine, due to decades lasting studies after the effects on local population, that survived the atomic-explosion of Hiroshima in 1945.

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 ...
At 07:30 JST, TEPCO prepared to release radioactive steam, indicating that "the amount of radiation to be released would be small and not of a level that would affect human health" [14] and manual venting took place at 08:41 and 09:20. [15]
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 ...
TEPCO was able to estimate radiation levels of 530 Sv/hr, the highest level measured since the March 2011 accident when the previous high was measured at 73 Sv/hr. [80] [81] [82] This does not represent an increase in radiation at the reactor, but rather is the first measurement taken in the containment vessel at this location. [83]
Japan marked the 13th anniversary of the massive earthquake and tsunami that triggered a nuclear meltdown and left large parts of Fukushima prefecture uninhabitable on Monday with a minute of ...
The hazard from contamination is the emission of ionizing radiation. The principal radiations which will be encountered are alpha, beta and gamma, but these have quite different characteristics. They have widely differing penetrating powers and radiation effects, and the accompanying diagram shows the penetration of these radiations in simple ...
