Study on gross-α、gross-β radioactivity level of groundwater in the northeast of Pingyin County,Jinan City
In order to investigate and study the total α and total β radioactivity levels ofgroundwater in the northeastern ar-ea of Pingyin County,Jinan City,and to explore the groundwater radioactivity risk and distribution pattern in the area.Using the analytical test data of 35 groundwater samples taken during June-July 2018,the evaluation was carried out based on the Health Standard for Domestic Drinking Water(GB/T 5749-2006)and the Groundwater Quality Standard(GB/T 14848-2017).The results showed that the total α radioactivity levels of four samples and the total β radioactivity levels of two sam-ples in the study area exceeded the guideline values of the Hygienic Standard for Drinking Water for Domestic Use(GB/T 5749-2006)and the limit value of Class Ⅲ water quality in the Groundwater Quality Standard(GB/T14848-2017),with the percentages of 11.43％and 5.71％,respectively,and these samples were all located in groundwater recharge and runoff areas.By comparing the total radioactivity levels with those of groundwater in some other regions of China in the last decade,the total α and β radioactivity levels in the study area are at the higher level of those regions.
