标准范围
ISO 18589-3:20 07规定了使用γ能谱法鉴定和测量土壤中大量发射γ的放射性核素的活性。这种非破坏性方法适用于大体积样品（高达约3 000 cm3），涵盖了光子能量在5keV和3MeV之间的所有g发射器的单次测量中的确定。ISO 18589-3:20 07可由执行常规放射性测量的测试实验室应用，因为大多数放射性核素的特征在于40keV和2MeV之间的γ射线发射。ISO 18589-3:20 07适用于环境监测和现场检查，并允许在发生事故时快速评估伽马活动。
ISO 18589-3:2007 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 g-emitters present for which the photon energy is between 5 keV and 3 MeV.ISO 18589-3:2007 can be applied by test laboratories performing routine radioactivity measurements as a majority of radionuclides is characterized by gamma-ray emission between 40 keV and 2 MeV.ISO 18589-3:2007 is suitable for the surveillance of the environment and the inspection of a site and allows, in case of accidents, a quick evaluation of gamma activity.
