DERIVATION OF RISK SCREENING VALUES FOR RADIOACTIVE CONTAMINATION OF SOIL IN NUCLEAR FACILITY DECOMMISSIONING

The Nuclear and Radiation Safety Center of MEE, Beijing 100082, China

摘要

摘要: 《中华人民共和国土壤污染防治法》规定了我国实施土壤污染风险管控制度，但我国土壤放射性污染风险管控制度尚未建立，未制定用于风险管控的土壤放射性污染筛选值。选用0.01 mSv/a作为筛选值确定的剂量准则，根据不同的土地利用用途，使用RESRAD软件程序，开展土壤放射性污染风险筛选值的计算推导，并将计算结果与美国核管会推荐的核素筛选值进行对比，确定了9种典型核素的土壤风险筛选值，以期为完善我国土壤放射性风险管控标准提供依据。

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.
