适用范围：This part of ISO 18589 specifies the identification and the measurement of the activity in soils of a largenumber of gamma-emitting radionuclides using gamma spectrometry. This non-destructive method, applicableto large-volume samples (up to about 3 000 cm3), covers the determination in a single measurement of all theγ-emitters present for which the photon energy is between 5 keV and 3 MeV.This part of ISO 18589 can be applied by test laboratories performing routine radioactivity measurements as amajority of radionuclides is characterized by gamma-ray emission between 40 keV and 2 MeV.This part of ISO 18589 is suitable for the surveillance of the environment and the inspection of a site andallows, in case of accidents, a quick evaluation of gamma activity.
