《GB/T 16140-1995水中放射性核素的γ能谱分析方法》由361(国家卫生健康委员会)归口,主管部门为国家卫生健康委员会。
本标准规定了使用高分辨半导体或NaI(TL)γ能谱仪测定水中放射性核素的方法。本标准适用于在实验室中分析特征γ射线能量大于50keV,活度不低于0.4Bq的放射性核素。
Scope
This standard specifies the method for the determination of radionuclides in water using a high-resolution semiconductor or NaI(Tl) gamma spectrometer. This standard is applicable to the analysis of radionuclides whose characteristic γ-ray energy is greater than 50keV and activity is not lower than 0.4Bq in the laboratory. If the full-spectrum count rate of the sample to be tested exceeds 1000 counts/s, appropriate dilution measures should be taken.
