BS EN ISO 9696:2017规定了非盐水中总α活性的测定方法 在350°C以下不易挥发的α放射性核素。该方法适用于原水和饮用水。应用范围取决于水中总可溶性盐的含量和温度 计数器的性能特征（背景计数率和计数效率）。实验室有责任确保该方法适用于测试的水样。交叉引用:ISO 11929:2010 Ed 1ISO 5667-3:2012 ED4ISO 3696:1987ISO/IEC指南98-3:2008 Ed 1ISO/IEC 17025:2005ISO 5667-1:2006 Ed 2（R10）ISO 80000-10:2009 Ed 1ISO/IEC指南99:2007ISO 5667-14:2014 Ed2IEA GS-R-2IEA GSG-2EN 5622:2006ISO 5667-20:2008 Ed 1购买本文件时可提供的所有现行修订版均包含在购买时。

BS EN ISO 9696:2017 specifies a method for the determination of gross alpha activity in non-saline waters for alpha-emitting radionuclides which are not volatile up to 350 °C.The method is applicable to raw and potable waters.The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter.It is the laboratory's responsibility to ensure the suitability of this method for the water samples tested.Cross References:ISO 11929:2010 Ed 1ISO 5667-3:2012 ED4ISO 3696:1987ISO/IEC GUIDE 98-3:2008 Ed 1ISO/IEC 17025:2005ISO 5667-1:2006 Ed 2 (R10)ISO 80000-10:2009 Ed 1ISO/IEC Guide 99:2007ISO 5667-14:2014 ED2IAEA GS-R-2IAEA GSG-2NEN 5622:2006ISO 5667-20:2008 Ed 1All current amendments available at time of purchase are included with the purchase of this document.
