摘要
使用同位素氡-222(^(222)Rn)示踪技术分析蒲石河抽水蓄能电站地下厂房渗漏水来源。从2013年9月~2013年12月一共测量了取自绕坝渗流检测孔、地下水、水库库水以及地下厂房渗漏水共计199个样品。测量结果显示,地下厂房渗漏水、地下水以及水库库水中的^(222)Rn活度平均值分别为1 634.2、37 887.3 Bq/m^3和2 343.7 Bq/m^3。地下厂房渗漏水体中氡-222活度值(1 634.2 Bq/m^3)与水库库水(2 343.7 Bq/m^3)具有相似性,这说明水库渗流水是地下厂房渗漏水的主要补给源。
The leakage water in Pushihe Pumped-storage Power Station is assessed by using radon-222 （^222 Rn）. A total of 199 water samples have been measured for ^222Rn concentration from September, 2013 to December, 2013 which covers seepage around the reservoir, groundwater in mountain, reservoir water and seepage water in underground powerhouse. The results show that the ^222 Rn activities of underground powerhouse leakage water, groundwater in mountain and reservoir water are 1 634.2 Bq/m^3, 37 887.3 Bq/m^3 and 2 343.7 Bq/m^3 respectively. The leakage in underground powerhouse has similar radon-222 concentration as reservoir water, it indicates that the reservoir seepage into underground is the main source for leakage in underground powerhouse.
