Abstract
The purpose of the research is to estimate the partial radiation doses to the population from radionuclides contained in various environmental components due to gas-aerosol releases of nuclear power facilities. The calculations were carried out for facilities with promising reactors of two different types – VVER-1200 and BREST-OD-300 in the complex with the enterprises of the stationary nuclear fuel cycle. The CROM code recommended by the IAEA was used as an assessment tool. The ranking of partial radiation doses forming the total dose from atmospheric releases was made. It is shown that the controlled radionuclides in the list of Sanitary rules for the design and operation of nuclear power plants are not the main dose-forming radionuclides for the facilities under consideration. The Methodological guidelines for the organisation of radioecological monitoring of agroecosystems in the area of impact of radiation hazardous facilities also do not pay attention to radionuclides, which are significant in terms of dose formation. The results of the calculations presented in the article can be used in the development of radioecological monitoring programmes aimed at assessing of public exposure from atmospheric releases within the compliance with dosimetric constraints (quotas) for the considered nuclear power facilities.
