April 26, 1986 - Chernobyl Disaster

1986 – A nuclear reactor accident occurs at the Chernobyl Nuclear Power Plant in the Soviet Union (now Ukraine), creating the world's worst nuclear disaster.


Chernobyl disaster 25th anniversary

On April 26, 1986, reactor number four at the Chernobyl nuclear power facility in what is now Ukraine exploded. The largest civil nuclear disaster in history led to mass evacuations, and long-term health, agricultural, and economic distress. The nearby city of Pripyat has been abandoned, and a 19-mile radius "exclusion zone" established where radiation contamination makes continued habitation dangerous. Collected here are archival pictures of the catastrophe, as well as more recent images of the area. In addition, two photographers who've made extensive studies of the aftermath have been gracious enough to share their work with us here. Diana Markosian documented the lives of pensioners Lida and Mikhail Masanovitz, who continue to live in the abandoned ghost town of Redkovka, Ukraine. Her work is found here in photographs 13 through 16. Michael Forster Rothbart has produced one of the most extensive records available of life near Chernobyl. His work is found here in photographs 23 through 29. Links to the websites of both photographers can be found below. -- Lane Turner (34 photos total)...[Full Article]

Chernobyl disaster

From Wikipedia, the free encyclopedia

The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the Ukrainian SSR (now Ukraine). An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western Russia and Europe. It is considered the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima I nuclear incident, which is considered far less serious and has caused no direct deaths).[1] The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy.[2]

The disaster began during a systems test on 26 April 1986 at reactor number four of the Chernobyl plant, which is near the town of Pripyat. There was a sudden power output surge, and when an emergency shutdown was attempted, a more extreme spike in power output occurred, which led to a reactor vessel rupture and a series of explosions. These events exposed the graphite moderator of the reactor to air, causing it to ignite.[3] The resulting fire sent a plume of highly radioactive smoke fallout into the atmosphere and over an extensive geographical area, including Pripyat. The plume drifted over large parts of the western Soviet Union and Europe. From 1986 to 2000, 350,400 people were evacuated and resettled from the most severely contaminated areas of Belarus, Russia, and Ukraine.[4][5] According to official post-Soviet data,[6][7] about 60% of the fallout landed in Belarus.

The accident raised concerns about the safety of the Soviet nuclear power industry, as well as nuclear power in general, slowing its expansion for a number of years and forcing the Soviet government to become less secretive about its procedures.[8][notes 1]

Russia, Ukraine, and Belarus have been burdened with the continuing and substantial decontamination and health care costs of the Chernobyl accident. Thirty one deaths are directly attributed to the accident, all among the reactor staff and emergency workers.[9] A UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. Estimates of the number of deaths potentially resulting from the accident vary enormously: the World Health Organization (WHO) suggest it could reach 4,000;[10] a Greenpeace report puts this figure at 200,000 or more;[11] a Russian publication, Chernobyl, concludes that 985,000 excess deaths occurred between 1986 and 2004 as a result of radioactive contamination.[12]...[Full Article]
