ISO 18589-4:2009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钚238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。所需试验部分的质量取决于样品的假设活性和所需的检测限。实际上,其范围为0.1 g至100 g试样。
ISO 18589-4:2009 describes a method for measuring plutonium 238 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.The mass of the test portion required depends on the assumed activity of the sample and the desired detection limit. In practice, it can range from 0,1 g to 100 g of the test sample.
