Natural radionuclides content of 238 U, 232 Th and 40 K for water and sediment samples collected from Asa-dam Ilonn. Nigeria weremeasured using Nal( TI ) detector. The mean activity concentration in the water samples were 6.05, 3.23 and 9.65 Bql −1 for 238 U, 232 Th and 40 K respectively. The mean activity concentration of 238 U, 232 Th and 40 K measured in the sediment samples were 7.57, 8.19 and 73.48 Bql −1 respectively. Theactivity concentration of 40 K was higher than that of 238 U and 232 Th for the water and sediment samples. All measured activity concentration and estimated radiological parameters were below world permissible limit values. Therefore, there may be no serious immediate radiological health burden on the environment and the people using the dam.
