摘要
依据水中总α、总β放射性活度浓度测量方法 HJ 898-2017和HJ 899-2017,采用厚源法,测定了鄂尔多斯市矿井水、医疗废水和地下水中总α、总β放射性活度浓度,测量结果均在国家标准要求范围内。为保证实验质量,从仪器检查、期间核查和不确定度评定三个方面探讨了水中总α、总β放射性测量实验方法的质量控制。
According to the method of measuring grossαand gross β radioactivity concentration in water HJ 898-2017 and HJ 899-2017,the grossαand gross β radioactive activity concentration of mine water,medical wastewater and underground water in Ordos City was measured by the method of thick source,and the results were all in the country's requirements.In order to guarantee the quality of measurement,the quality control of the experimental method of total alpha and total beta radioactivity measurement in water is discussed from four aspects:instrument inspection,period verification and uncertainty evaluation.
