摘要
γ能谱分析作为可给出Y放射性核素种类及活度的一种快速分析方法,被广泛应用于环境和生物样品中Y放射性核素的测量.《环境及生物样品中放射性核素的γ能谱分析方法》(GB/T 16145-2022)已经发布,并于2023年7月1日起实施,替代《土壤中放射性核素的γ能谱分析方法》(GB/T 11743-2013)、《水中放射性核素的γ能谱分析方法》(GB/T 16140-2018)、《生物样品中放射性核素的γ能谱分析方法》(GB/T 16145-2020)和《空气中放射性核素的γ能谱分析方法》(WS/T 184-2017)等4项标准.本文就标准修订的背景、主要修订的内容和依据和一些需要探讨的问题进行了简要说明,以期能为土壤、水、生物、空气及类似基质样品的放射性检测提供有用的参考.
Abstract
As a rapid analytical method for both the types and activities of γ radionuclides,the γ-ray spectrometry method is widely used in the measurement of γ radionuclides in environmental and biological samples.The Gamma-ray Spectrometry Method for the Determination of Radionuclides in Environmental and Biological Samples(GB/T 16145-2022)was imple-mented on July 1,2023,replacing the Determination of Radionuclides in Soil by Gamma Spectrometry(GB/T 11743-2013),Determination of Radionuclides in Water by Gamma Spectrometry(GB/T 16140-2018),Gamma Spectro-metry Method of Analyzing Radionuclides in Biological Samples(GB/T 16145-2020),and Determination of Radionuclides in Air by Gamma Spectrometry(WS/T 184-2017).The background of the revised standard,the content and basis of the main revisions,and some issues that need to be discussed are briefly explained in this paper,in order to provide a useful ref-erence for the detection of radioactivity in soil,water,biological,and air samples,as well as samples of similar matrices.
