Yabloxo WWW site, Nov. 19, 2009: article dated Oct. 25, 2002: (On September 29th 1957, one of the cooling pipes in one of Mayak's radioactive waste tank systems overheated and exploded. The force of the explosion was equal to 75,000 tonnes of TNT. The total release of radioactivity was 740 PBq, and 90 percent of the radionuclides (666 PBq) were spread over a small area near the tank. About 74 PBq of the total activity was swept up to a height of one kilometre, leading to the radioactive contamination of certain parts of neighbouring Sverdlovsk and Tyumen regions and on Chelyabinsk, home to one million people. The most potent isotope of the long-lived isotopes present in the ensuing fallout in what has come to be known as the Kyshtym Tragedy was the 90Sr. This radionuclide accounted for approximately 5.4 percent of the fallout, or 4 PBq; Mayak disaster) Home today's release archive, WWW site, Nov. 19, 2009 (One of the largest ecological catastrophes of human kind at the nuclear industrial complex "Mayak" is also known as "Kyshtym tragedy") Vikipedia, Sept. 14, 2009 (Kyshtymskai︠a︡ tragedii︠a︡, krupnai︠a︡ radiat︠s︡ionnai︠a︡ tekhnogennai︠a︡ avari︠a︡, proizoshedshai︠a︡ 29 senti︠a︡bri︠a︡ 1957 g. na khimkombinate "MAI︠A︡K"; Kishtims tragedy [rom]) Wikipedia, Nov. 19, 2009: Mayak (nuclear fuel processing plant between the towns of Kasli and Kyshtym, 72 km NW of Chelyabinsk in Russia; serious accident in 1957; Kyshtym disaster) |
