Abstract: The peculiarities of the concentration and redistribution of the artificial radionuclide 90Sr in ecosystem components in the salt lakes of the Crimea (Kyzyl-Yar, Donuzlav, Dzharylhatch, Bakalskoye, Kiyatskoe, Kirleutskoe, Chokrak, Aktashskoye, Koyashskoye) were identified and described for the first time. The radiochemical, chemical analytical research methods and statistical methods of data processing were applied. It was found that the highest 90Sr concentration in water of the Kiyatskoe (350.5 Bq/m3) and Kirleutskoe (121.3 Bq/m3) lakes were caused by discharge of the Dnieper river waters from the North-Crimean channel into these lakes. It was identified that the redistribution of 90Sr between the water, bottom sediments and aquatic plants of the salt lakes of the Crimea is negligible. The absorbed doses (3.2×10-6 Gy/yr) of the 90Sr in the hydrophytes in the salt lakes of Crimea did not have any significant radiation effects on aquatic plants for the period after the Chernobyl NPP accident
