Radiological hazard parameters of natural radionuclides for neoproterozoic rocks from Wadi Um Huytat in central eastern desert of Egypt

AbstractThe aim of this study is to evaluate the radioactivity levels and radiological impacts of representative neoproterozoic rocks: monzogranite, dokhan volcanics, syenogranite, granodiorite, gabbro and metabasalt samples collected from Wadi Um Huytat region in central eastern desert of Egypt using HPGe detector and Alpha GUARD. Remotely sensed data (Landsat 8 OLI) also used in order to appear the high reflectance appearance of neoproterozoic rocks which contain high concentration of radioactive elements. Rhyolite rocks have the highest average concentration of radionuclides of226Ra,232Th,40K and222Rn. Our results aimed to shed more light on the spatial distribution of natural radionuclides in neoproterozoic rocks.
