Measuring of accumulation of gamma-radiation radionuclide’s are conducted in the bottom sediment and mollusks of Mytilus galloprovincialis in the littoral area of Black Sea exterminating within the limits of Odessa. The got results compared to information on contamination of offshore waters after twelve indexes. The results of supervisions exhibit correlation between the accumulation of natural radionuclide’s the components of biogeocenosis of littoral area exterminating some indexes of contamination of offshore waters. Including, with maintenance suspended solids, biochemical demand of oxygen, phosphates, total ferrum and other. It is suggested to use the value of specific activity of natural radionuclide’s and dose-rate of gamma-radiation as indicators of contamination of littoral zone exterminating the products of weathering of build materials.
