Abstract

In this study, indoor radon concentration (CRn) were measured by solid state nuclear track detectors in bare mode using CR-39 inside fifteen dwelling at different locations in Baghdad governorate for a period two months. The Potential Alpha Energy concentration (PAEC) in Working Level (WL) of radon daughters, exposure to radon progeny (EP) in (WLM Y-1), the annual effective dose (mSv/y) and the lung cancer cases per year per million person (CPPP) have been studied. The results show that the radon concentration ranged from 83.4 Bq/m3 in Topchi to 238.8 Bq/m3 in Baya with average 116.78 Bq/m3, Potential Alpha Energy concentration values of radon daughters varies from (0.009 to 0.026) WL with an average value of 0.02WL, the annual effective dose rate from 2.10 to 6.02 mSv/y with average 2.95 mSv/y, exposure to radon progeny from 3.71 to 10.62 WLM Y-1 with average 5.2WLMY-1 and the lung cancer per year per million person from 0.88 to 4.46 with average 1.7. The indoor radon concentration was in agreement to radon concentration levels (200 Bq/m3) recommended by the International Commission on Radiological Protection (ICRP).
