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 wa-ter and groundwater were stable in Fujian region from 2019 to 2020,and there were no abnormalities.The radio-activity in water from drinking water sources met the national standard.
