摘要
Based on the monitoring data and calculation of the integral indicator of pollution in the components of the natural environment, the radioecological situation was analyzed in the observation area of Mayak Production Association, FSUE (Federal State Unitary Enterprise), including the territory of the East Ural radioactive trace. The control levels of radionuclides in atmospheric air, soil, and surface waters were assessed on the basis of environmental criteria, taking into account the specifics of radioactive contamination of the territory in accordance with the Recommendations of Roshydromet. To assess the control levels of radionuclides in the components of the natural environment, elk (Alces alces) was identified as a critical organism of the terrestrial biota, and the bottom fish common carp (Cyprinus carpio) was identified as critical in the aquatic biota. The long-term dynamics of the integral indicator of pollution with technogenic radionuclides (Sr-90, Cs-137, Pu-239) in the components of the natural environment are presented. The analysis of the radiation situation did not reveal an excess of the environmentally safe level of biota irradiation for the integral indicator of pollution of the components of the natural environment in the observation area of the enterprise. For a modern assessment of the radioecological situation in the area of the location of the Mayak Production Association FSUE, it is necessary to take into account the radioactive contamination of the territory associated with the past activities of the enterprise.
