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动物性食物样品中放射性核素的监测结果如下:猪肉中137Cs9、0Sr3、H含量分别为0.08、0.060、0.7 Bq/kg(鲜重),猪骨为0.05、0.662、0.2 Bq/kg(鲜重);羊肉中137Cs9、0Sr含量分别为0.03、0.112Bq/kg(鲜重),羊骨为0.02、0.754 Bq/kg(鲜重);牛奶中137Cs9、0Sr3、H含量分别为0.019、0.025、0.6 Bq/L;奶粉中137Cs含量为0.18 Bq/kg(鲜重);鲻鱼中137Cs9、0Sr含量分别为0.05、0.127 Bq/kg(鲜重),3H含量为1.9 Bq/L;螺蛳中137Cs、90Sr含量分别为0.03、1.80 Bq/kg(鲜重)。与基地运行前本底值和对照点监测值相比,各类动物性食物样品中放射性核素含量均在正常范围内。
Since 1992, Environmental Radiation Monitoring Center of Zhejiang Province has been conducting a continued monitoring of environmental radiation levels in animal samples around the QNPP Base. The moni- toring results during 1992-2005 are： 0.08, 0.060, 0.7 Bq/kg （fresh weight） for 137^Cs, 90^Sr, 3^H in pork and 0.05, 0.662, 0.2 Bq/kg （fresh weight） in pork bone; 0.03, 0.112 Bq/kg （fresh weight） for 137^Cs, 90^Sr in mutton and 0.02, 0.754 Bq/kg （fresh weight） in sheep bone; 0.019, 0.025, 0.6 Bq/L for 137^Cs, 90^Sr, 3^H in milk; 0. 18 Bq/kg （fresh weight） for 137^Cs in dried milk; 0.05,0. 127 Bq/kg （fresh weight） for 137^Cs, 90^Sr and 1.9 Bq/L for 3^H in mullet; 0.03, 1.80 Bq/kg （fresh weight） for 137^Cs, 90^Sr in spiral shell. The radionuclide contents in those animal samples are all fall in the normal range.
