Prediction of the exposure of atmospheric releases from Baltic nuclear power plant to members of the public and non-human biota

Abstract

Abstract The article presents a long-term prediction of radiation doses to members of the public and reference organisms of biota from planned radioactive atmospheric releases by the Baltic nuclear power plant with VVER-1200. The calculation of atmospheric dispersion and radiation dose to the population have performed on the basis of general models presented in the IAEA Safety Report Series No. 19. The radiation doses to non-human biota have calculated using the ERICA Tool. Annual effective dose to the population near the Baltic NPP are expected to be below 2.1 μSv. The dose rate of reference organisms will not exceed 0.6 nGy/h. The main contribution to the irradiation of both population and non-human biota will be made by 14C and 3H. It has recommended to include these radionuclides in the radioecological monitoring program of natural and agricultural ecosystems in the area where the Baltic NPP is located.
