摘　　要：饮用水的放射性安全引起了公众越来越多的关注,我国新颁布的《生活饮用水卫生标准(GB5749-2022)》对放射性指标进行了修订。本文综述了饮用水中放射性的主要来源、存在水平和所致个人剂量的健康效应,对放射性指标的相关制修订内容进行了分析和讨论,包括常规指标总α和总β放射性筛查指导值、总β扣除钾-40、参考指标铀和镭-226限值的制定依据等,并提出了具体的实施与评估的建议。The radioactive safety of drinking water has attracted increasing public concern.The newly issued Standards for Drinking Water Quality(GB5749-2022)in China has revised the radiological parameters.This article provides an overview of the main sources,levels of radionuclides in drinking water,and summarized the individual doses criterion and adverse health effects associated with exposure of the public to radionuclides from drinking-water.It analyzes and discusses the relevant revision content of radiological parameters,including the guidance values for screening grossαand grossβ,subtracting the contribution of potassium-40 from grossβactivity when the grossβactivity concentration exceeds the screening level,and the basis for establishing the limit values of reference indices uranium and radium-226.Specific implementation and evaluation suggestions are also proposed.
