Factors Controlling Natural Radionuclides Migration in Sedimentary Rock Samples, Gabal Um‐Hamd, Southwestern Sinai, Egypt

Abstract

The activity concentrations of some radionuclides ( 238 U, 234 U, 230 Th, 226 Ra, 232 Th, 40 K and 235 U) were measured by γ-ray spectrometry in order to study their behavior and the relation between them in Carboniferous rock samples collected from Gabal (mountain) Um-Hamd, southwestern Sinai, Egypt. The whole samples are located in the two limbs and trough of a synclinal form structure to identify the radionuclides migration processes which have occurred in these rock samples. The average activity concentrations of 238 U

Analysis of Naturally Occurring Radioisotopes in Peat moss Greenhouse Soils and Agriculture Mud in Egypt

“…The system was energy calibrated to display gamma photo‐peaks between 63 and 3000 keV. The efficiency calibration was performed by using three well‐known reference materials obtained from the International Atomic Energy Agency for U, Th, and K activity measurements; namely, RGU‐1, RGTh‐1, and RGK‐1 …”

Significance of Uranium Series Disequilibrium and Their Radiological Impacts In Abu Garadi Altered Granites.

“…Gamma-ray spectrometry is the common techniques used to detect low-background radioactivity. The hyper-pure germanium (HPGe) gamma ray spectrometry is the most sensitive and effective tool used to evaluate radionuclide activity from lower to pCi (Harpy et al, 2019;El-Taher, 2011).…”
