Abstract:
Objective To determine the gross radioactivity in drinking water in Chifeng city and to estimate the annual effective dose associated with intake of radionuclides from drinking water.Methods Water samples were collected at locations distributed in 12 counties across Chifeng city, and radioactivity was measured with a low background α/β measuring instrument and HPGe γspectrometer.Results Gross α radioactivity in drinking water was in the range of 0.016-1.230 Bq/L and gross β radioactivity in the range of 0.039-0.878 Bq/L in Chifeng city.The average annual effective dose to the local population from gross α radioactivity was 0.071 mSv/a.Conclusions The grossα/β level in Chifeng city is lower than the World Health Organization-recommended value and the average annual effective dose due to drinking water is within the recommended safety level.
