Abstract
New data on the concentration of 137Cs in the water and bottom sediments of the Sea of Azov are analyzed. The factors determining the entry and redistribution of technogenic radionuclides in the seas are discussed. The increased background of radioactivity in the Sea of Azov is supported by the recirculation of radionuclides transported after the accident at the Chernobyl nuclear power station.
