Abstract: |
Granites from the Southeastern Desert of Egypt were investigated radiometrically in the field using in situ γ-ray spectrometer. Consequently, estimating the radiological effects from these rocks through the calculation of some radiological parameters: radium equivalent activity Raeq, gamma activity concentration index Iγ, alpha activity index Iα, external hazard index Hex, internal hazard index Hin, annual effective dose equivalent AEDE, annual gonadal dose equivalent AGDE and Excess lifetime cancer risk, ELCR. The geological structure of the region under investigation was affected by the radioactivity levels of the rocks under study. This was observed by the high U, Th, and K values, which exceed the average world value for safety used as building materials. the granites of Om Ara may be inappropriate to choose as a building material or as an indoor and outdoor decorative. At the same time, the study region represents a significant economic source of minerals, and their metal values can use in several industrial applications |
