秦山核电基地外围90Sr、137Cs公众摄入量估算及内照射剂量评价
INTAKE ESTIMATION AND DOSE ASSESSMENT OF 90Sr, 137Cs AROUND QNPP BASE
摘要
Abstract
90Sr and 137Cs are important radionuclides in environmental investigation related to nuclear power stations. A mode of intake estimation and dose assessment via various food chains is made in this paper. Based on daily food consumption and dietary composition for Chinese reference man and for man of Zhejiang province and the concentration of 137Cs and 90Sr around QNPP Base, the intake estimation and dose of 90Sr and 137Cs around QNPP Base are calculated. It shows that the main food sources of intake of 90Sr and 137Cs are rice, vegetable and aquatic product. Also the public average annual committed effective dose of 90Sr (2.5 μSv) is obviously higher than the contribution of dose of the 137Cs (0.36 μSv). A practical estimation method was made by taking QNPP Base as an example in this paper,while no background change occurs after its commercial operation.关键词
