Abstract

Indoor radon levels in 20 dwellings of rural areas at the Kozak-Bergama (Pergamon) granodiorite area in Turkey were measured by the alpha track etch integrated method. These dwellings were monitored for eight successive months. Results show that the radon levels varied widely in the area ranging from 111 to 72711 Bq m(3) and the geometric mean was found to be 63 Bq m(3) with a geometric standard deviation of 2 Bq m(3). A lognormal distribution of the radon concentration was obtained for the studied area. Estimated annual effective doses due to the indoor radon ranged from 0.27 to 18.34 mSv y(1) with a mean value of 1.95 mSv y(1), which is lower than the effective dose values 310 mSv given as the range of action levels recommended by International Commission on Radiation Protection. All dosimetric calculations were performed based on the guidance of the UNSCEAR 2000 report.
