Abstract
The paper presents the results of monitoring tritium in various types of water environments in the area of the city of Ozyorsk, Chelyabinsk region, which is under the influence of the Production Association «Mayak». An excess of the level of the technogenic background of the radionuclide was revealed in all the studied water bodies (rain, snow, lake water, drinking water of the city, ice). A significant excess of tritium concentrations in rainfall in the city of Ozyorsk was found in comparison with the control territories (Chebarkul, Yekaterinburg). The difference in the levels of tritium content in the city’s tap water and frozen water in the refrigerators of residential premises is shown, which can be explained by different sources of the radionuclide entering the indicated aquatic environments. Elevated concentrations of tritium in the urine of residents of the city of Ozyorsk were revealed as a result of above-background contamination of the water environment of the study area with radionuclide. These studies indicate the need to develop methods for treating emissions and discharges of tritium into the environment to reduce risks to public health.
