  ABSTRACT: This study measured the radioactivity level in the sediments of Eko-Ende Dam in Ifelodun Local Government Area, Osun State, Nigeria and assessed the radiological impact associated. Thirty six (36) sediment samples were collected from three different points within the Dam for a period of 12 months. The samples were analyzed using Gamma Ray Spectrometer. The radiological hazards due to natural radionuclides content, such as absorbed dose rate (DR), annual effective dose rate (AEDE), effective life cancer risk (ELCR), activity utilization index (AUI), internal radiation hazard (Hin) and external radiation hazard (Hex) in the sediment samples were calculated. The calculated radiological parameters were compared with recommended safety limits and internationally approved values. The radium equivalent activity, internal hazard index, annual effective dose equivalent and effective life cancer risk values of the sediment samples were lower than the permissible limit. Thus, the study area might not pose immediate health implications to the general public, but prolonged exposure could lead to radiation related health hazards.
