Measurements of radioactivity in the environment - Soil - Part 4: Measurement of plutonium isotopes (plutonium 238 - plutonium 239 + 240) by alpha spectrometry (ISO 18589-4:2009, IDT)

Status: Withdrawn · Replaced by: SS-ISO 18589-4:2020

This part of ISO 18589 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.
