| 摘 要： | 2019—2020年在福建省设置河流、湖泊（水库）、饮用水源地水、地下水监测点位，定量分析水中总α、总β放射性活度浓度。试验表明：河流总α、总β放射性活度浓度测定值分别为0.004 Bq/L～0.130 Bq/L、0.056 Bq/L～0.840 Bq/L，湖泊（水库）测定值分别为0.005 Bq/L～0.057 Bq/L、0.066 Bq/L～0.170 Bq/L，饮用水源地水测定值分别为0.001 Bq/L～0.103 Bq/L、0.039 Bq/L～0.243 Bq/L，地下水测定值分别为0.012 Bq/L～0.110 Bq/L、0.046 Bq/L～1.10 Bq/L。说明2019—2020年福建地区地表水、地下水总α、总β放射性变化稳定，未出现异常，饮用水源地水放射性水平符合国家标准。

| Abstract: | From 2019 to 2020， monitoring points in rivers， lakes (reservoirs)， drinking water sources and groundwater were set up in Fujian to quantitatively analyze the gross α and gross β activities. The test showed that gross α and gross β activities were 0.004 Bq/L～0.130 Bq/L and 0.056 Bq/L～0.840 Bq/L in rivers， 0.005 Bq/L～0.057 Bq/L and 0.066 Bq/L～0.170 Bq/L in lakes（reservoirs）， 0.001 Bq/L～0.103 Bq/L and 0.039 Bq/L～0.243 Bq/L in water from drinking water source， 0.012 Bq/L～0.110 Bq/L and 0.046 Bq/L～1.10 Bq/L in groundwater， respectively. The results indicated that gross α and gross β activities in surface water and groundwater were stable in Fujian region from 2019 to 2020， and there were no abnormalities. The radioactivity in water from drinking water sources met the national standard. |
