The monetary value of the man-mSv for Korean NPP radiation workers assessed by the radiation aversion factor.

The monetary value of the man-Sv(man-sievert) for operators of Korean nuclear power plants (NPPs) was calculated using the radiation aversion factor analyzed based on a survey of NPP workers. Initially, the life expectancy in population of 79.4 years, average age of cancer occurrence of 60 years, average annual wage for electric worker of 56,000 $/year, and nominal risk coefficient induced by radiation of 4.2ESv were used to evaluate the basic monetary value(αbase) resulting in 45.6 $/mSv. To evaluate the risk aversion factor, radiation workers were surveyed, of which 2,157 responded. The assessed risk aversion factor and the monetary value of the man-Sv from the calculated risk aversion factor were 1.26 and approximately 50 $ in the 0-1 mSv range, 1.38 and approximately 200 $ in the 1-5 mSv range, 1.52 and approximately 1,000$ in the 5-10 mSv range, 1.65 and approximately 4,000 $ in the 1020 mSv range, and 1.74 and approximately 8,500 $ above 20 mSv.
