Exposure to radon in dwellings in the Sharri community, Kosovo

Indoor air radon concentration was measured by exposing etched track detectors in the sleeping and living rooms of 18 houses in 6 villages of the Sharri community in Kosovo. Values ranged from 24 to 209 Bq m(-3), with only one exceeding 200 Bq m(-3), with a geometric mean and geometric standard deviation of 95.4 Bq m(-3) and 1.6, respectively. On the basis of the assumption that the spring radon concentrations obtained in this survey represent the yearly average, annual effective doses of residents were calculated; they range from 0.89 to 4.7 mSv y(-1), with the geometric mean and geometric standard deviation of 1.5 mSv y(-1) and 2.2, respectively. No mitigation measures are planned to be undertaken.
