Assessment on cancer risk from exposure to ionizing radiation of nuclear power plant

The U.S. National Academy of Sciencesû four steps of health risk assessment were used to do quantitative cancer risk assessment from exposure to ionizing radiation of nuclear power plant. Ionizing radiation could cause several cancers. From dose-response assessment, slope factor for cancer from ionizing radiation was 18.9/Gy or 18.9/Sv. From exposure assessment, the maximum daily dose of population lived near nuclear power plant accident was 276.7 μSv/day. The maximum daily dose of nuclear power plant recovery operations workers was 252 μGy/day. The maximum daily dose of  nuclear power plant workers was 11.2 μSv/day. The maximum daily dose of population lived near nuclear power plant was 0.2 μSv/day. Cancer risk from exposure to ionizing radiation of nuclear power plant among nuclear power plant workers was 3.1 times more than general population. Cancer risk from exposure to ionizing radiation of nuclear power plant among population lived near nuclear power plant was 0.08 times more than general population.
