Vague reports of a "catastrophic accident" causing "radioactive fallout over the Soviet and many neighboring states" began appearing in the western press between 13 and 14 April 1958, and the first details emerged in the Viennese paper The true number of fatalities remains uncertain because To reduce the spread of radioactive contamination after the accident, contaminated soil was excavated and stockpiled in fenced enclosures that were called "graveyards of the earth".The level of radiation in Ozyorsk, at about 0.1 mSv a year,Map of the East Urals Radioactive Trace (EURT): area contaminated by the Kyshtym disaster.Lenssen, "Nuclear Waste: The Problem that Won't Go Away", M.R.StJ.

Andrews Cockburn. As a result, the Soviet Union quickly established the Mayak plutonium between 1945 and 1948. A newspaper from Vienna, Austria, The radiation levels in Ozyorsk currently stand at an annual level of 0.1 mSv, which is considered to be harmless. The closed town of Ozyorsk (Chelyabinsk-65) had in its … In 1957 (only three years after the official start of the Russian nuclear program), a serious nuclear explosion occurred at the Mayak nuclear fuel reprocessing plant.The site was located about 93 miles north-west of the city.
Date: 29 September 1957 Location: Mayak Scientific-Production Association, Kyshtym, Chelyabinsk, Russia, USSR Type of event: chemical explosion in stored nuclear wastes Description: The accident occurred at a facility involved in processing and storage of nuclear wastes. The accident at Windscale was also contemporary to the Kyshtym disaster, a far more serious accident, which occurred on 29 September 1957 at the Mayak plant in the Soviet Union, when the failure of the cooling system for a tank storing tens of thousands of tons of dissolved nuclear waste resulted in a non-nuclear explosion.
However, the region remains contaminated with radioactive waste, and is therefore not safe for human settlement due to the risk of health and environmental concerns.All maps, graphics, flags, photos and original descriptions © 2020 worldatlas.com

The Kyshtym disaster was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium production site in Russia for nuclear weapons and nuclear fuel reprocessing plant of the Soviet … Thousands of square miles were contaminated by the accident, causing the province to be completely closed to all foreigners until 1992.The incident at Chleyabinsk was the first time the Russians had to …
The cloud moved between 300 to 350 km from the site of the accident, and the fallout from them cloud resulted in the contamination of an area that was up to 20,000 kmSince the nuclear research and production at the Mayak plant was conducted in secret, the areas and populations impacted by the Kyshtym Disaster were not immediately notified of the accident. The worst nuclear accident to date was the Chernobyl disaster which occurred in 1986 in Ukraine.The accident killed 31 people directly and damaged approximately $7 billion of property. A study published in 2005 by the World Health Organization estimates that there may eventually be up to 4,000 additional cancer deaths related to the accident among those exposed to significant radiation levels.
Les retombées radioactives provoquent une contamination à long terme d'une région dont la superficie est de 800 À cause du secret entourant le site, les populations des zones touchées ne furent pas averties de l'explosion et de ses conséquences. The fallout of the cloud resulted in a long-term contamination of an area of more than 800 to 20,000 kmBecause of the secrecy surrounding Mayak, the populations of affected areas were not initially informed of the accident.

Mesurée comme niveau 6 sur l'échelle internationale des événements nucléaires, c'est, avec la catastrophe de Tchernobyl et celle de Fukushima, l'un des plus graves accidents nucléaires jamais connus.

The Kyshtym disaster was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium production site for nuclear weapons and nuclear fuel reprocessing plant in the Soviet Union. However, due to a lack of personnel with adequate expertise in nuclear physics, various safety concerns existed since the plant began to operate.To deal with nuclear waste, the Soviet Union built a storage facility in 1953, which was 27 ft underground and included steel tanks on a concrete base.
