ASSESSMENT OF ANNUAL EFFECTIVE DOSE DUE TO THE INDOOR RADON EXPOSURE IN A SECOND-DEGREE EARTHQUAKE ZONE OF KUTAHYA (TURKEY)

Abstract

Indoor radon concentrations have been measured in 100 dwellings of Central Kutahya, Turkey, using LR-115 type II Solid-State Nuclear Track Detectors. The detectors were placed in living rooms during the period of March May 2010 for three times. The annual indoor radon concentrations vary from 74.1+/-2.4 to 272.3 +/- 4.2 Bq m(-3), with a mean value of 120.8 +/- 2.0 Bq m(-3). Based on these results, we find an annual effective dose varying from 1.9 to 6.9 mSv, with a mean value of 3 mSv y(-1) received by inhabitants living in Kutahya city.
