本文件规定了测量锕系元素（238Pu，？239+240Pu，？241Am，242Cm，243+244Cm和237Np）的测试方法。在适当的取样和处理以及测试样品制备后，该方法可用于任何类型的环境研究或监测。试验方法的检出限为5 × 10？3 Bq·l-1至5 × 10？4？Bq·l-1，测试部分的体积在0,1之间？l到5？l计数时间为两到十天。这低于世卫组织安全饮用饮用水的标准（1 Bq·l-1或10？Bq·l-1，取决于放射性核素）。[4]本文件中描述的方法适用于紧急情况。
This document specifies a test method for measuring actinides (238Pu, 239+240Pu, 241Am, 242Cm, 243+244Cm and 237Np) in water samples by alpha spectrometry following a chemical separation.
This method can be used for any type of environmental study or monitoring after appropriate sampling and handling, and test sample preparation.
The detection limit of the test method is 5 × 10？3 Bq·l-1 to 5 × 10？4 Bq·l-1 for a volume of test portion between 0,1 l to 5 l with a counting time of two to ten days. This is lower than the WHO criteria for safe consumption of drinking water (1 Bq·l-1 or 10 Bq·l-1 depending on radionuclide).[4]
The method described in this document is applicable in the event of an emergency situation.
