%X 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. </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">The radiological
hazards due to natural radionuclides content, such as absorbed dose rate (D</span><sub><span style=\"font-family:Verdana;\">R</span></sub><span style=\"font-family:Verdana;\">),
annual effective dose rate (AEDE), effective life cancer risk (ELCR), activity
utilization index (AUI), internal radiation hazard (H</span><sub><span style=\"font-family:Verdana;\">in</span></sub><span style=\"font-family:Verdana;\">) and
external radiation hazard (H</span><sub><span style=\"font-family:Verdana;\">ex</span></sub><span style=\"font-family:Verdana;\">) in the sediment samples were
calculated. The calculated radiological parameters were compared with
recommended safety limits and internationally approved values.</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">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.
