Abstract: Island nuclear power plant is one important trend for site selection currently. “Technical guidelines for environmental impact assessment format and content of environmental impact reports for nuclear power plants” (HJ 808—2016) explicitly requires radiation estimation caused by nuclear power plants on non-human organisms. But there is little research in the area of island nuclear power plant radiation effects on the surrounding island organisms. In this paper, we use designed gaseous emission of a Nuclear power plant and ERICA program, along with the results of island local ecological survey, to estimate the radiation and risk of radioactive effluent on island organisms, and carry out the “Three Key Analysis”. The results show that the radiation dose rate of the nuclear power plants on island organisms is less than 10 μGy/h of ERICA dose screening values, and the overall radiation risk is quite low. In view of the applicability of some parameters in ERICA program (such as dose conversion coefficient and concentration ratio), the future research direction is suggested.
