Abstract

Abstract

The Law of Soil Pollution Prevention and Control of the People's Republic of China has stipulated that we should implement a soil pollution risk control system. However, the risk control system of soil radioactive pollution has not been established, and no screening value of soil radioactive pollution for risk control has been formulated. The research selected 0.01 mSv/a as a screening value to determine dosage guidelines, used RESRAD software program to calculate and deduce the screening values of soil radioactive contamination risk, according to different land-use types, and then compared the calculated results with the nuclide screening values recommend by United States NRC, and determined the soil risk screening values of 9 nuclide species. The research can provide a basis for improving the soil radioactivity risk control standards in China.
