摘　　要：目的了解攀枝花市生活饮用水总α和总β的放射性水平,为饮用水风险监测提供参考依据。方法采用整群抽样方法,对攀枝花市集中式生活饮用水生产企业的水源水总α和总β放射性水平进行监测,并依据GB5749-2006《生活饮用水》和WHO《生活饮用水准则》对监测结果进行评价。结果 2016年攀枝花市监测水样总α活度浓度平均值为0.054 Bq/L,总β平均值为0.098 Bq/L,居民通过饮用水所致辐射暴露的年均有效剂量为0.014 m Sv,均低于GB5749-2006放射性指标指导值和WHO的推荐限值。结论攀枝花市饮用水放射性安全水平安全可靠。Objective To investigate the radioactivity levels of total α and total β in drinking water in Panzhihua and provide reference for monitoring the risk of drinking water. Methods Using the cluster sampling method, the radioactivity levels of total α and total β in source water of drinking water manufacturersin Panzhihua were monitored, and the results were evaluated according to the Chinese Standard GB5749 -2006 ＂Standard for drinking water quality＂ and WHO ＂ Guidelines for drinking - water quality＂. Results In 2016, the mean concentration of total α was 0. 054 Bq/L, and the mean concentration of total β was 0. 098 Bq/L. The annual average effective dose of radiation exposure from drinking water was 0. 014 mSv, which was lower than the guiding value of radioactivity index specified in GB5749 -2006 and the recommended limit in WHO ＂Guidelines for drinking -water quality＂. Conclusion The radioactivity level of drinking water is safe and reliable in Panzhihua.
