Nuclear Disaster

Fukushima Daiichi Nuclear Disaster
• The Fukushima Daiichi nuclear disaster was a catastrophic failure at the Fukushima I Nuclear Power Plant on 11 March 2011, resulting in a meltdown of three of the plant's six nuclear reactors. The failure occurred when the plant was hit by the tsunami triggered by the Tōhoku earthquake. • It is the largest nuclear incident since the Chernobyl disaster and the second (after Chernobyl) to measure Level 7 on the International Nuclear Event Scale, initially releasing an estimated 10-30% of the earlier incident's radiation.
Atomic Bombings of Hiroshima and Nagasaki
• The atomic bombings of the cities of Hiroshima and Nagasaki in Japan were conducted by the United States during the final stages of World War II in August 1945. The two bombings were the first and remain the only use of nuclear weapons in wartime. • A uranium gun-type atomic bomb (Little Boy) was dropped on Hiroshima on August 6, 1945, followed by a plutonium implosion-type bomb (Fat Man) on the city of Nagasaki on August 9. Within the first two to four months of the bombings, the acute effects killed 90,000–166,000 people in Hiroshima and 60,000–80,000 in Nagasaki; roughly half of the deaths in each city occurred on the first day. During the following months, large numbers died from the effect of burns, radiation sickness, and other injuries, compounded by illness. In both cities, most of the dead were civilians, although Hiroshima had a sizeable garrison.

Chernobyl Nuclear Disaster
• The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine • The Chernobyl disaster is the worst nuclear power plant accident in history in terms of cost and resulting deaths, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale.

Residual radioactivity in the environment:Rivers, lakes and reservoirs.Groundwater was not badly affected by the Chernobyl accident since radionuclides with short halflives decayed away long before they could affect groundwater supplies, and longerlived radionuclides such as radiocaesium and radiostrontium were adsorbed to surface soils before they could transfer to groundwater.After the disaster, four square kilometers of pine forest directly downwind of the reactor turned reddish-brown and died, earning the name of the "Red Forest".
