本国际标准规定了一种在化学分离后，通过α光谱法测量水样中锕系元素（238Pu、239+240Pu、241Am、242Cm、243+244Cm和237Np）的试验方法。该方法可用于任何类型的环境研究或监测。所需试验部分的体积取决于样品的假设活性和所需的温度 检测极限。试验方法的检测限为5×10-3至5×10-4Bq/l，试验部分的体积为0.1 l至5 l，计数时间为2至10天。交叉引用:ISO 5667-1ISO 5667-3ISO 11929ISO 80000-10ISO/IEC 17025NF M 60-790-8:1999ISO/IEC指南98-3GUM:1995购买本文件时提供的所有当前修订版均包含在购买本文件中。

This International Standard specifies a test method for measuring actinides (238Pu,239+240Pu,241Am,242Cm,243+244Cm and237Np) in water samples by alpha spectrometry following a chemical separation.The method can be used for any type of environmental study or monitoring.The volume of the test portion required depends on the assumed activity of the sample and the desired detection limit.The detection limit of the test method is 5 × 10-3to 5 × 10-4Bq/l for a volume of the test portion of 0,1 l to 5 l with a counting time of two to ten days.Cross References:ISO 5667-1ISO 5667-3ISO 11929ISO 80000-10ISO/IEC 17025NF M 60-790-8:1999ISO/IEC Guide 98-3GUM:1995All current amendments available at time of purchase are included with the purchase of this document.
