Natural Radionuclide Concentrations by γ-Ray Spectrometry in Granitic Rocks of the Sol Hamed Area, Southeastern Desert of Egypt, and Their Radiological Implications

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 rocks. obtained data on for 238U (610 ± 1730 Bq kg−1), 232Th (110 69 kg−1) (1157 467 (GR) higher than recommended worldwide average. levels found caused by materials being altered trapped inside faults. exposure gamma radiation from assessed via various parameters, radium equivalent content (856 absorbed dose rate (Dair) air (396 nGy/h), annual effective either outdoor (0.48 mSv y−1) or indoor (1.9 y−1).
