Potassium (40K), Uranium (238U) and Thorium (232Th) are radionuclides that are present in drinking water sources naturally or artificially. The exposure of humans and animals to these radionuclides in minute doses may cause chronic health issues in the future. This work analyzed the level of activity concentrations of Potassium 40K, 238U and 232Th in borehole water used for drinking and other domestic activities. Twenty-nine (29) samples were collected in a one-litre cylindrical air-tight polyvinylchloride container, thoroughly washed and sterilised. The samples were analyzed using a well-calibrated thallium-activated 3x3 Sodium Iodide NaI(Tl) detector at the Institute of Radiation Protection and Research (NIRPR). The results of the analyses showed that the activity concentrations of 40K, 238U and 232Th have mean values of 110.39 ± 19.21, 9.35 ± 2.01, and 5.21 ± 2.56, respectively, which were all above the world average recommended values of WHO and UNSCEAR. Therefore, the use of the water for drinking is toxic and detrimental to the physiology and the overall health status of the consumers.
