Reports suggest that there are few or no road signs warning about the polluted areas surrounding Lake Karachay.
Lake Karachay, located in the southern Ural Mountains in eastern Russia, was a dumping ground for the Soviet Union's nuclear weapon facilities. This is more than sufficient to kill a human being.
In 2010, the concentration of Sr in water of this reservoir was found to be 6.5 × 10(6) Bq L, the concentration of 137Cs was 1.6 × 10(7) Bq L, and total alpha activity amounted to 3.0 × 10(3) Bq L. An increased level of nitrates was observed in the reservoir-4.4 g L. It has been demonstrated that in this reservoir under the conditions of the maximum contamination levels known for aquatic ecosystems in the entire biosphere, a phytoplankton community exists that has a pronounced decline in species diversity, almost to the extent of a monoculture of widely-spread thread eurytopic cyanobacteria Geitlerinema amphibium.
As the Cold War waged on, it ramped up production, supplying plutonium for most of America’s 60,000 nuclear weapons. Although decommissioned, it still holds two thirds of the volume of the country’s high-level radioactive waste — about 53 million gallons of liq… The status of the phytoplankton community in Lake Karachay, a storage reservoir of liquid medium-level radioactive waste from the Mayak Production Association, Chelyabinsk Region, Russia, is reviewed. Besides Karachay, the waste was also thrown into Techa River that became the water source to majority of the people there. Well, Mayak was a secret until it started to appear on the map in the 1990’s. However, it soon got contaminated because of the open-cycle system making Lake Karachay, which is much closer to the reactors, a quick dumping site for nuclear waste that was too hot for the underground storage vats. They built a secret nuclear facility that used the water from nearby lakes for cooling and dumping wastes. Characteristics of phytoplankton in Lake Karachay, a storage reservoir of medium-level radioactive waste. According to Basement Geographer, the last reactor in the area closed in 1990, so the radiation will only have gone down since then.
Atamanyuk NI(1), Osipov DI, Tryapitsina GA, Deryabina LV, Stukalov PM, Ivanov IA, Pryakhin EA. So, between 1978 and 1986, Russian engineers have gradually filled the lake with concrete blocks to prevent airborne contamination. They used an open-cycle cooling system and the water used for cooling the reactors was being contaminated by thousands of gallons every day.Two years after its existence was revealed, Boris Yeltsin, the then Russian president, signed a decree allowing access to western scientists. Although today the lake is completely infilled, almost the whole bed of the lake is composed of high level of radioactive waste. As for the actual lake itself, Karachay presently emits nearly 600 Röntgens per hour.
The radiation of the levels their claiming make it sound like the lake is full of very short half life atoms that to this day have not degraded at all. But, that proved to be impossible because of the immensely lethal levels of radiation and added to that was the 1957 Kyshtym Disaster caused by the explosion of underground vats contaminating the entire Mayak area.
The goal of building the plant was to match the nuclear power of United States and it was given the utmost priority after the atomic bombings in Japan.
Considering the size of Karachay that is not so big, only about 45 hectares, the level of exabecquerels reaches 4.44 with 3.6 EBq of caesium-137. Youcan imagine how much of the compound you can possibly inhale while stayingaround the lake and endanger your health.Can you find Lake Karachay on the map? When Mayak’s existence was officially acknowledged, the region of Chelyabinsk was found to have a 21 percent increase in cancer cases, a 25 percent increase in birth defects, and a 41 percent … In 2010, the concentration of Sr in water of this reservoir was found to be 6.5 × 10(6) Bq L, the concentration of 137Cs was 1.6 × 10(7) Bq L, and total alpha activity amounted to 3.0 × 10(3) Bq L. An increased … The status of the phytoplankton community in Lake Karachay, a storage reservoir of liquid medium-level radioactive waste from the Mayak Production Association, Chelyabinsk Region, Russia, is reviewed. One of those lakes, Lake Karachay, was used so much for dumping radioactive waste by 1990 that just standing beside it would have given you enough radioactive dose to kill you.Lake Kyzyltash was the largest natural water body capable of providing cooling water for the reactors nearby.
