英文摘要	The level of natural radioactivity in eight sediment rock samples collected from western south Sinai from three different locations Um Bogma, Wadi Um Hamd and wadi Sad El-Banat, were measured. Also, two granite samples, collected from Gabal Gattar, north eastern desert in Egypt was investigated. The gamma-ray spectrometry system with hyper pure germanium (HPGe) detector was been used to determined radioactivity concentrations. Samples were subjected to sulphuric acid leaching processes with the same parameters of solid liquid ratio S/L, acid concentration and leaching time. After the leaching process, the pregnant solution was separated from the residual and the latter was dried. The two units, named the pregnant solutions and residuals were also measured radiometrically using the HPGe detector to determine the activity concentrations (Bq/kg) of the different radionuclides of samples. The results showed that the relation between the sum of activities of U-238 in both solutions and residuals with originals have two modes. The first mode is represented by the sum of U-238 activities in leachate and residual is nearly equal the activity in the original sample. While the second mode, the sum is higher than the original. These variations depend mainly on the grain surfaces in the different rock types and its content high Pb concentration. This phenomenon varied in magnitude within the different radionuclides in each sample. Also, the leachability of U by the chemical analysis using several acidic leaching experiments for uranium have been performed using sulfuric acid.
