摘要
为探究聊城市岩溶地下水水源地的放射性及辐射剂量情况,本文根据2022—2023年总α、总β放射性监测结果对年辐射剂量进行了估算。结果显示,总α、总β放射性浓度值均在《生活饮用水卫生标准》(GB 5749—2022)提出的指导值范围内,但2022年总α辐射体中210Po的年辐射剂量估算值超出了世界卫生组织给出的个人辐射剂量标准值0.11倍。因此,常规性开展水源地水源的总放射性监测尤为重要。
In order to investigate the radioactivity and radiation dose of karst groundwater sources in Liaocheng City,this paper estimated the annual radiation dose based on the monitoring results of totalαand totalβradioactivity from 2022 to 2023.The results show that both totalαand totalβconcentrations comply with Hygienic Standards for Drinking Water(GB 5749-2022).However,the estimated annual radiation dose of 210Po in the totalα-radiation body in 2022 exceeded the World Health Organization’s recommended limit by 11%.Therefore,it is still of great importance to conduct routine monitoring of the total radioactivity of water sources,and relevant monitoring suggestions are put forward.
