Abu Garadi area is mainly represented by metasediments, alkali feldspar granites and stream sediments. The granitic mass described different degrees of hydrothermal alterations like albitization, g...
Radioactivity of U, Th series and 40K in the collected samples from Abu Garadi area were measured using Hyper Pure Germanium detector Gamma spectrometer (HPGe). 232Th, 226Ra, 40K and 238U contents were determined in the different samples that indicat
