In order to determine the natural radionuclides in portable water, samples were collected from fifty locations in Northern part of Kaduna state and were subjected to the investigation of the presence of naturally occurring radionuclides. The radionuclides investigated are potassium-40, uranium-238 and thorium-232 using sodium iodide detector (NaI (Ti)). Results showed that potassium-40 concentration in the water samples has minimum and maximum concentration as 0.124 and 0.849 Bq/L, respectively. The mean value of potassium-40 concentration found in water is 0.416 Bq/L. Also, uranium-238 and thorium-232 investigated in the samples gave mean concentration of 0.0011 and 0.00006 Bq/L, respectively. The results obtained from these analysis shows that samples have radionuclides activity concentration below the recommended value for the radionuclides.
