NF EN ISO 18589-3

<p>ISO 18589-3:2015 specifies the identification and the measurement of the activity in soils of a large number of gamma-emitting radionuclides using gamma spectrometry. This non-destructive method, applicable to large-volume samples (up to about 3 000 cm³), covers the determination in a single measurement of all the γ<i>-</i>emitters present for which the photon energy is between 5 keV and 3 MeV.</p> <p>ISO 18589-3:2015 can be applied by test laboratories performing routine radioactivity measurements as a majority of gamma-emitting radionuclides is characterized by gamma-ray emission between 40 keV and 2 MeV.</p> <p>The method can be implemented using a germanium or other type of detector with a resolution better than 5 keV.</p> <p>ISO 18589-3:2015 is addressed to people responsible for determining gamma-emitting radionuclides activity present in soils for the purpose of radiation protection.</p>
