摘要：
The 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 of(226)Ra,Th-232,K-40 and(222)Rn. Our results aimed to shed more light on the spatial distribution of natural radionuclides in neoproterozoic rocks.
