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).
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).
Fukushima fishing returned to normal operations in 2021, and the local catch is now about one-fifth of its pre-disaster level because of a decline in the fishing population and smaller catch sizes.

The Chernobyl disaster in 1986 exposed to radiation about 125,000 mi 2 (320,000 km 2) of land across Ukraine, Belarus, and Russia. [155] The amount of focused radiation caused severe damage to plant reproduction: most plants could not reproduce for at least three years.
Overview map showing evacuation and other zone progression and selected radiation levels. 05:30: In order to release some of the pressure inside the containment at unit 1, the decision is made to vent some of the steam (which contained a small amount of radioactive material) into the air, despite the risk of hydrogen (produced from the water in ...
Twelve years after the Fukushima nuclear disaster, Japan has started to release treated radioactive water into the sea, a key step in the process of decommissioning the stricken plant, but much ...
