Abstract
In 2016, for the first time a radioecological study was made of 11 salt lakes of the Crimea to investigate the contamination of their ecosystems by 137Cs and 90Sr. There was a positive correlation between the salt content and the concentration of anthropogenic radionuclides 90Sr and 137Cs in the water of the studied groups of lakes. Absorbed doses of 137Cs and 90Sr radiation in aquatic plants in the lakes were 7.7.10-6 and 3.2.10-6 Gy/year, respectively, and lay within the “Uncertainty Zone” according to the scale “Zones of Chronic Exposure to Ionizing Radiation”, proposed by Polikarpov.
