In order to determine exposure to natural sources of radiation for people in the vicinity of a southern China uranium company, six sites included a school, a hospital and four residential areas were investigated from September 2006 to march 2008. The surveys evaluated indoor radon concentrations and outdoor and indoor external gamma dose rates. Indoor radon concentrations were measured in 98 dwellings by means of nuclear track-etched detectors. The terrestrial gamma ray dose rate was measured outdoors and indoors at a total of 148 points and 85 points, respectively. The results show that the total mean annual effective doses for the six areas studied ranged from 3.6 to 5.9 mSv per year, which is between 1.8 and 2.8 times higher than the HengYang average value. Applying the BEIR VI model to the areas studied, the population-weighted average lifetime risk of lung cancer can get 1.9×10^-4.
