摘要: 采用蒸发浓缩γ谱测量的方法分析了珠江水中的131I,实验证实15 L水样于pH值=7、碘载体浓度为0.5 mg/L的条件下蒸发浓缩,131I的加标回收率为95%、探测下限为0.004 Bq/L;2011~2013年监测珠江广州段水中131I浓度范围为0.03~0.20 Bq/L。

Abstract: 131I was measured by gamma spectrometer for water in Pear River in Guangzhou. 15 L water was vaporized in condition of pH=7 and 0.5 mg/L iodine. The recovery rate of 131I is 95%and the lower detection limit is 0.004 Bq/L. The concentration of 131Iis 0.03-0.20 Bq/L during 2011-2013.
