Radionuclide pollution in Lake Karachay, Russian Federation.
Lake Karachay, in the Chelyabinsk region, is a prime example of the consequences of human carelessness. This seemingly harmless, undrained body of water is several times more deadly than the hazards of Chornobyl. To date, 12 to 15 million curies of long-lived radionuclides such as cesium-137 and strontium-90 have accumulated in the waters of Karachay. The fog that rises over the lake contains such a dose of radiation that a huge area would be exposed to contamination in the event of a tornado or hurricane. In 2015, the lake was covered with concrete and rock slabs. However, environmentalists are sure that Karachay is a potential radioactive threat even today.",
