Background: Natural radionuclides are always present in the environment. Human exposure to the background radiation is inevitable. It is therefore important to assess health risk associated with these radionuclides. Materials and Methods: The distribution of natural radionuclides 238U, 232Th and 40K in soil samples collected from all the twenty (20) local Governments headquarter areas in Ogun s...

This study was conducted to determine and compare the activity concentration of natural radioactivity 238U, 232Th, 40K in borehole well water samples collected from Lokoja Nigeria, using Sodium Iodide−Thallium gamma spectroscopy. Samples selected wells were standard radiation protocol analyzed. The result shows that sample 2.77±0.67 Bq/l; 2.30±0.27 Bq/l 1.66±0.13 for respectively, 17.62±1.37 wh...

There is concern that work scenarios on the tantalite mining sites in Oke-Ogun, Oyo State, Nigeria may cause occupational radiation exposure of workers due to enhanced concentrations naturally occurring radionuclides some process materials. A prior radiological assessment activities was carried out determine if and which require protection measures. Samples materials involved, comprising (tanta...

The occurrence of heavy radioactive minerals in construction supplies such as granite has drawn attention to the extraction minerals. Granitic rocks were identified serve an essential economic role study area’s surrounding locations. As a result, current attempted detect activity concentrations 238U, 232Th, and 40K granitic rock samples tested estimate radiological dangers associated with these...
