Abstract
Abstract 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 5 × 5 km 2 grid showed radon prone areas in the region.
