Abstract
In order to explore the features of natural radionuclides in different types of drinking water sources,the radioactivity concentrations of total α,total β,Unatural,Thnatural,226Ra,40K,210Pb and 210Po in groundwater and surface water centralized drinking water sources in a certain area were monitored and analyzed.The results showed that the total α and total β radioactivity levels and natural radionuclide contents such as 40K and 226Ra were regularly distributed in different types of drinking water sources,the total α and total β in drinking water in the area did not exceed the limit values stipulated in GB 5749-2006(total α≤0.5 Bq/L,total β≤1 Bq/L),and the radiation environment of drinking water sources in this area was safe and controllable.关键词
