Description
Summary:Data accumulated over many years of observations of radioecological conditions are used to analyze the accumulation coefficients for technogenic radionuclides in hydrobionts in interior bukhtas and zalivs in the north-western part of the Sea of Japan. Attention is focused on estimating the contribution of technogenic radionuclides to the dose according to their accumulation coefficients in marine biota and to determine more accurately the contribution of natural super(40)K to the total dose in the operational regions of nuclear-powered ships. On individual local sections of bukhtas and zalivs, the dose due to external irradiation from technogenic radionuclides in bottom deposits exceeds the natural level (regions of radiation accident in bukhta Chazhma, near the nuclear-powered submarine with the damaged nuclear power system in bukhta Pavlovskogo). However, the total dose due to technogenic irradiation of hydrobionts as a whole remains low and falls outside the dose range at which negative effects of radiation for marine organisms are observed.
