中文摘要自1992年,浙江省辐射环境监测站对秦山核电基地外围环境辐射水平进行了连续的监督性监测。1992~2005年,秦山核电基地外围环境电离辐射水平和各种介质放射性水平的监测结果如下:在正常运行下,秦山核电基地外围环境γ辐射剂量率平均为96nGy/h;大气气溶胶总α、总β比活度分别为0.11、0.45mBq/m3;环境大气中3H浓度为71.6mBq/m3,14CO2浓度为0.30Bq/g(碳);沉降物总β比活度为0.81Bq/m2d;陆地环境淡水(饮用水、湖塘水、井水)中总α、总β、90Sr、137Cs浓度分别为65、151、4.4、0.3mBq/L,3H为1.0Bq/L,雨水3H浓度为2.8Bq/L;正常排放下基地附近海域海水样品90Sr、137Cs平均浓度分别为5.4、0.7mBq/L,3H为1.0Bq/L;土壤、湖塘泥、潮间带土、海底泥137Cs平均比活度分别为3.3、1.9、2.4、1.1Bq/kg(干重);食用植物样品中,大米90Sr、137Cs、3H平均比活度分别为0.06、0.14、0.4Bq/kg,青菜为0.27、0.04、3.1Bq/kg(鲜重),萝卜为0.10、0.03、2.5Bq/kg(鲜重);指示植物样品中,茶叶90Sr、137Cs、3H平均比活度分别为3.4、0.49Bq/kg(干重)和4.6Bq/kg(鲜重),松针分别为9.8、0.10、7.7Bq/kg(鲜重);肉类动物样品中,猪肉90Sr、137Cs平均比活度分别为0.06、0.08Bq/kg(鲜重),羊肉为0.11、0.03Bq/kg(鲜重),牛奶为0.03、0.02Bq/kg(鲜重),奶粉137Cs平均比活度为0.18Bq/kg(干重),鲻鱼90Sr、137Cs平均比活度分别为0.13、0.05Bq/kg(鲜重)。; Since 1992, continuous supervisory monitoring of environmental radioactive levels around QNPP base was launched. The monitoring results with respect to both environmental radiation levels and in-media radioactivity levels measured during 1992~2005 are as follows. In normal operation, the γ radiation dose rate around QNPP base was measured to be 96 nGy/h; the specific activity of gross α and β was estimated to be, respectively, 0.11 and 0.45 mBq/m3; in the environmental air, the concentrations of 3H and 14CO2 are respectively 71.6 mBq/m3 and 0.30 Bq/g(carbon); the gross β specific activity in fallout is 0.81 Bq/m2d;the concentrations of gross α,β,90Sr and 137Cs in terrestrial environmental freshwater (drinking water, lake water, well water are respectively 65, 151, 4.4 and 0.3 mBq/L; the 3H concentration in rainfall is 2.8 Bq/L, in normal discharge conditions, the average concentrations of 90Sr and 137Cs in sea water near the QNPP base 5.4 and 0.7 mBq/L respectively and 3H is 1.0 Bq/L;the average specific activity of 137Cs in soils, lake mud, intertide zone and seafloor sediment are 3.3, 1.9, 2.4 and 1.1 Bq/kg(dried) respectively; for edible plants, the average specific activity of 90Sr, 137Cs and 3H are 0.06, 0.14 and 0.4 Bq/kg in rice, 0.27, 0.04 and 3.1Bq/kg in vegetables (dried), 0.10, 0.03 and 2.5 Bq/kg in dried turnip; as plant sample indicator, 90Sr, 137Cs and 3H are 3.4, 0.49 Bq/kg (dried) and 4.6 Bq/kg (fresh) in tea and 9.8, 0.10 and 7.7 Bq/kg(fresh) in pine needle (fresh); for animal meal sample, the average specific activity of 90Sr and 137Cs in pork is respectively 0.06 and 0.08 Bq/kg(fresh), 0.11 and 0.03 Bq/kg in mutton (fresh), 0.03 and 0.02 Bq/kg in milk (fresh); the average specific activity of 137Cs in milk powder is 0.18 Bq/kg(dried), the average specific activity of 90Sr and 137Cs in mullet is 0.13 and 0.05 Bq/kg (fresh).
