The average radon activity concentration in all the water samples was 12.41 Bql−1. The maximum and minimum activity concentrations of radon were 22.5 and 4.57 Bql−1, respectively. In total, 53% of the total samples analysed had radon concentration levels above the US Environmental Protection Agency-recommended limit of 11.1 Bql−1. The annual dose received by an individual as a result of waterborne radon was determined according to the United Nations Scientific Committee on the Effect of Atomic Radiation reports and was found to be 33.23 μSvy−1.
