摘要：
In this work, the indoor radon concentration and radiation dose risks were studied in dwellings within the Greater Accra region, using CR-39 detectors. The indoor radon concentrations ranged from 36.1 +/- 2.7 to 92.0 +/- 5.2 Bq m( -3) with an annual average of 50.8 +/- 3.4 Bq m( -3). The annual mean effective dose was estimated as 1.3 mSv year(-1). Excess lifetime cancer risk and lung cancer cases were assessed with 5% annual lung cancer deaths due to radon was realized. Indoor radon maps created with ArcGIS software over a 5x5 km(2) grid showed radon prone areas in the region.
