本文描述了一种使用化学分离技术通过阿尔法光谱法样品测量土壤中238钚和239+240同位素的方法。 该方法可用于任何类型的环境研究或监测。这些技术还可用于测量非常低的放射性水平，比天然α放射性核素水平低一到两个数量级。交叉引用:ISO 18589-2ISO 18589-1ISO 11074ISO/IEC指南98-3ISO 80000-10ISO/IEC 17025NUREG-1576ISO 5667-12ISO 5667-17ISO 5667-19ISO 11929（所有部分）NF M 60-790-8ISO 16000-11EN 16516ISO 5667-13购买本文件时提供的所有当前修订版均包括在内。

This document describes a method for measuring238Pu and 239 + 240 isotopes in soil by alpha spectrometry samples using chemical separation techniques. The method can be used for any type of environmental study or monitoring. These techniques can also be used for measurements of very low levels of activity, one or two orders of magnitude less than the level of natural alpha-emitting radionuclides.Cross References:ISO 18589-2ISO 18589-1ISO 11074ISO/IEC Guide 98-3ISO 80000-10ISO/IEC 17025NUREG-1576ISO 5667-12ISO 5667-17ISO 5667-19ISO 11929 (all parts)NF M 60-790-8ISO 16000-11EN 16516ISO 5667-13All current amendments available at time of purchase are included with the purchase of this document.
