The article presents a description of the developed database containing up-to-date information on a wide range of regional parameters that allow, on their basis, to assess both the current radiological situation in NPP locations and predictive assessments during normal operation, design basis and beyond design basis accidents. The created database contains regional radioecological data for all nuclear power plants in the Russian Federation within the framework of two main information blocks. The first block contains information on planned, actual and emergency emissions from NPPs, the second block contains data characterizing meteorological conditions, features of agroecosystems and the content of natural and artificial radionuclides in their components, parameters of radionuclide migration, and diets of the population. As an example of using the database, an analysis of the radioecological situation formed by atmospheric emissions from the Kursk NPP was performed. The population exposure doses were calculated using the CROM software package and information collected in the database. The article presents the results of assessing dose loads on different age groups of the population in the period from 2002 to 2030. The contributions of various exposure routes and radionuclides to the annual effective dose of radiation to the population are estimated. It is shown that the total annual dose of public exposure from atmospheric emissions is significantly lower than the limit of the annual effective dose justified in NRB-99/2009 and the minimum value of the quota for public exposure. The developed database will be updated with both up-to-date information obtained during the monitoring of the studied territories and annual reports on atmospheric emissions of nuclear power plants, as well as calculated data obtained during model calculations.
