Dynamics of changes in the levels of radioactive contamination of environmental objects of the Volga-Vyatka region of the Russian Federation

Abstract

The Volga-Vyatka region is safe for radioactive contamination, but due to the annual increase in organizations using man-made sources of ionizing radiation, the increase in radiation-hazardous objects, their physical aging, as well as systems, complexes and means of physical protection, it is necessary to constantly monitor the radiation situation of both the Volga-Vyatka region and other subjects of the Russian Federation. During the analysis of the radiation situation in the Volga-Vyatka region of the Russian Federation, the following conclusions were made, namely, in recent years, the indicators of the specific activity of artificial radionuclides in the soils of the Volga-Vyatka region remain at stable levels. Their content does not exceed the background values of radioactive contamination of the soil for the territories of the Russian Federation. Pollution of the atmosphere by technogenic radionuclides in the territory of the Russian Federation is now caused by the secondary arrival of radionuclides from the territories polluted in previous years and emissions of the enterprises of the nuclear fuel cycle. In General, the content of technogenic radionuclides on the territory of the Volga-Vyatka region does not exceed the values of permissible annual volume activities for the population. Regular monitoring of the radiation situation in the Volga-Vyatka region makes it possible to detect any changes in the levels of radioactive contamination of environmental objects in a timely manner and to take the necessary measures to protect the population from exposure to ionizing radiation.
