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0.5mg/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。
131 I 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 131 I is 95% and the lower detection limit is 0 .004 Bq/L .The concentration of 131 I is 0 .03-0 .20 Bq/L during 2011-2013 .
