Drinking water samples obtained from different groundwater sources in Ekiti State, Nigeria were assayed for radon concentration with the aid of a Durridge RAD7 electronic radon detector. In the three types of well considered, higher radon contents were found in hand-dug wells with manual pumps while hand-dug wells with removable covers presented the least radon content. The total annual effective dose incurred through the consumption of groundwater in the study area is found to be within the guideline value of 0.1 mSv recommended by European Union and WHO.
