Abstract
The assessment of the radiation dose from the artificial (137Сs) and natural radionuclides (210Po, 40K, 232Th, 238U, 234Th, 226Ra) obtained by the cysts and adults of Artemia spp. from the salt lakes of the Crimea (Kirleutstkoye, Dzharylgach, Sasyk-Sivash, Aktashskoe) was carried out for the first time in the history of radioecological research in the Crimean region. The Scale of the Zones of a chronic effect of ionizing radiation, proposed by G.G. Polikarpov, was used to compare the obtained results. It was determined that 210Po was the main dose-forming radionuclide for cysts and adults of Artemia from the salt lakes of the Crimea. The average absorbed dose rate of 210Po radiation on adult crustaceans was 6.8 × 10–2 Gy per year, which was an order of magnitude more than for cysts. The radiation dose from anthropogenic 137Сs and natural (40K, 232Th, 238U, 234Th, 226Ra) radionuclides was insufficient to produce detectable influence both on cysts and adults of Artemia spp. from the salt lakes of the Crimea.
