【 摘 要 】

Problem statement: Manganese ore is widely used in muchindustries. Such as ore contain natural radioactive nuclides at various concentrations. If this ore contain high concentrations of natural radioactive nuclides, workers handling them might be exposed to significant levels of radiation. Therefore it is important to determine the radioactive nuclides in this ore. Approach: The natural radionuclides (²³⁸U, ²³²Th and ⁴⁰K) contents of Manganese ore samples collected by Siani Manganese Company in Egypt-Cairo have been determined by low background spectroscopy using hyper-pure germanium (HPGe) detector. Results: The mean activities due to the three radionuclides (²³⁸U, ²³²Th and⁴⁰K) were found to be 3543
