摘要
本文报道了辽宁省34个县、镇自来水的总α、总β和铀含量。测定结果表明,县、镇自来水的总α、总β和铀含量范围分别为0.011～0.244、0.07～0.36、0.002～0.212Bq.1^(-1),均值分别为0.052,0.15,0.026Bq.1^(-1)。总α超标率为5.9％。
This paper described gross a, gross β and Uranium(U) contents of drinking water in County and Tow, of Liaoning Province. The results sho- wed that the gross a, gross β and U contents ran- ged 0.011~0.244, 0.07~0.36 and 0.002~0.212 and the mean values were 0.052, 0.15, 0.026Bq·l^(-1), respectively, The excesive sanitary standard ratio of gross a is 5.9%.
