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238Pu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。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document describes a method for measuring 238Pu 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.All current amendments available at time of purchase are included with the purchase of this document.
