The purpose of this work is to assess the impact of domestic and foreign nuclear power plants on the radiation situation on the border of Ukraine and to compare contributions to the radiation situation of nuclear power plants under normal operating conditions and in the event of a predicted radiation accident. Research methods - mathematical modeling of the distribution of artificial radioactive substances in the atmospheric air and falls on the soil surface. Calculations have been carried out and the radiation effect of the consequences of emissions of radioactive substances from nuclear power plants on the border of Ukraine and neighboring countries during normal operation and in case of emergency situations has been substantiated. The choice of meteorological conditions in emergency situations was carried out on the basis of estimating the doses of the population, as a result, the most adverse weather conditions were selected, at which the doses are maximum (conservative approach). It is shown that the maximum exposure dose rate for adults at the borders of Ukraine does not exceed the permissible limit doses in conditions of normal operation of power units. The average expected effective doses over 50 years for the post-PAD population are small compared to the annual effective dose. According to the report of the Un Scientific Committee on the Effects of Atomic Radiation to the UN General Assembly in 1993, the annual effective dose from natural sources of radiation in regions with normal background radiation is 2.4 mSv, which is more than the average for ZPA. The risk of fatal effects from cancer and the risk of causing general damage from diseases were as Product Description popup.authors popup.nrat_date 2022-03-09 Close
