摘　　要：目的调查分析2013—2018年宁夏黄河水、湖水和深井水源水总α、总β放射性水平的本底值,为掌握宁夏水资源的放射性水平提供数据支持。方法分别采集宁夏枯水期和丰水期的黄河水、湖水和深井水源水水样各27份,采用BH1216Ⅲ型二路低本底α、β检测仪按照《生活饮用水标准检验方法放射性指标》(GB/T5750.13—2006)进行样品分析。结果2013—2018年宁夏地区黄河水、湖水和深井水源水的总α、总β放射性水平的中位数分别为0.090和0.110 Bq/L、0.100和0.190 Bq/L及0.047和0.073 Bq/L,黄河水、湖水和深井水源水比较,湖水总α、总β放射性水平最高,黄河水次之,深井水源水最低,差异有统计学意义(P<0.05),枯水期与丰水期总α、总β放射性水平差异无统计学意义(P>0.05),不同年份比较,总α放射性水平有升高趋势,总β放射性水平先升高后降低。结论宁夏2013—2018年湖水、深井水源水总α、总β放射性水平处于正常范围,未超出《生活饮用水卫生标准》(GB 5749—2022)指导值,水样总放射性水平与固体残渣具有线性相关性。Objective To understand the grossαand grossβradioactivity levels of the Yellow River water,lake water and deep well source water from 2013 to 2018 and provide the data support for grasping the radioactivity levels of water resource in Ningxia.Methods Twenty-seven samples were collected from the Yellow River water,lake water and deep well source water in dry season and wet season respectively in Ningxia,and the grossαand grossβradioactivity levels were determined by BH1216Ⅲtype two-channel low-backgroundαandβdetector according to the“Standards for Drinking Water Standard Test Method Radioactivity Index”(GB/T 5750.13-2006).Results From 2013 to 2018,the medians of grossαand grossβradioactivity concentrations in the Yellow River water,lake water and deep well source water were 0.090 and 0.110 Bq/L,0.100 and 0.190 Bq/L,0.047 and 0.073 Bq/L,respectively.Comparison of the Yellow River water,the lake water and deep well source water,the radioactivity levels of grossαand grossβin the lake water were the highest,followed by the Yellow River water and deep well source water,with significant differences(P<0.05),and there were no significant differences in grossαand grossβradiation levels between dry season and wet season(P>0.05).Compared with different years,the radiation levels of grossαhad an increasing trend,and the levels of grossβincreased first and then decreased.Conclusion The grossαand grossβradioactivity levels in the lake water and deep well source water in Ningxia from 2013 to 2018 were in the normal range,and did not exceed the guidance values of the“Sanitary Standard for Drinking Water”(GB 5749-2022),the total radioactivity levelsin the water samples were linear independence with the solid residue.
