In the late 1940s, the USSR began intensive production of plutonium for atomic weapons. close the towns of Kysztym and Oziorsk the Majak complex was created with 5 reactors. The environment was not taken care of - radioactive waste went straight to Lake Karaczaj. Initially, it was to be a temporary solution, but the planned underground landfills were never built.

How did they clean up after the Kyszty disaster? The incidental resulted in a massive contamination
In September 1957, 1 of the largest atomic disasters in history, the alleged Kishtym disaster, occurred. The failure of the cooling strategy of the atomic waste tank led to an detonation and the contamination covered an area of 39,000 square kilometres. Over 200 people died of radiation sickness, 10,000 were evacuated, and 470,000 were exposed to ionizing radiation. any sources propose that the number of victims may have been even higher, but for years the russian authorities hid details of the cataclysm. Contaminated areas included extended areas of confederate Ural, and residents were unaware of the real threat. In subsequent years, there was a crucial increase in cancer and genetic diseases among those surviving in the area.

In 1967, as a consequence of the drought, the water level in Lake Karachaj fell and exposed a layer of radioactive sediment. The wind spread toxic dust throughout the region and caused contamination of surrounding villages and cities. It is estimated that about 400,000 people have been irradiated, many of whom have begun to endure from previously unknown ailments, including immune strategy problems and neurological diseases. The contamination of groundwater further aggravated the problem and caused radioactive substances to enter human organisms through water and food consumed. russian authorities were silent - to the 1957 disaster they had not formally admitted until 1992.
What is the most radioactive lake in the world? The tank is gone, but the threat remains
In the following decades, attempts were made to reduce the effects of contamination. The dry lake was filled with concrete blocks, rocks and earth. The work was completed in 2015. To this day, however, it is not known to what degree buried waste affects groundwater. There are concerns that liquids can gradually transfer radioactive substances and origin contamination of subsequent sites. There has never been adequate thorough investigation to measure the risks, which raises concerns among scientists and environmentalists. According to focuss.pl portal, there is information that "the level of contamination is so advanced that if we are located between 30 and 60 minutes close the lake, we will exposure ourselves to a lethal dose of radiation".
