摘要:In this present work, the indoor radon concentration, the annual effective dose rate, the annual dose equivalent rate to the lung and the populace risk were estimated in sandcrete houses of Dome in Ghana using time-integrated passive radon detectors. LR-115 Type II Solid State Nuclear Track Detector (SSNTD) technique was used for the measurements were for a period of 3months. The mean annual effective dose rate and the mean annual equivalent dose rate to the lung in the studied area were (14.13±0.22) mSv/y and (3.74 E-07 ±3.50 E-06) Sv/y, respectively. The mean indoor radon concentration was (466.9±1.2) Bq/m3. The odds ratio for the study at 95% confidence interval was 7 (CI 0.92-53.16). The indoor radon concentration has not only been found to vary considerably with the ventilation condition but also w ith the lifestyle of the people. The results obtained also give a correlation between indoor radon levels and the associated level of risk.
