“…The total yield of the radiotracer consists of free [ 125 I] -iodide and [ 125 I] -ZEN it is calculated from the percentage (%), on TLC at RTs (retention times) 0.0 and 0.9–1.0 respectively. HPLC analysis revealed the following, the purity for [ 125 I]-ZEN reached 99 % [ [101] , [102] , [103] , [104] , [105] , [106] , [107] , [108] , [109] , [110] , [111] , [112] , [113] , [114] , [115] , [116] , [117] , [118] , [119] , [120] ]. The Retention times values for both the free iodide and the labeled molecule [ 125 I]-ZEN existed at 4.5 and 15.8 min, respectively, with regard to the retention time for ZEN that was 14.7 min ( Fig.…”

“…However, it is important to ensure that the conditions of the irradiation and measurement are consistent between the sample and standard, as any differences could affect the accuracy of the analysis. Additional detailed descriptions can be found in refs [33][34][35][36][37][38]. Induced radioactivity was measured using an N-type HPGe detector, model Comp-100.250-S, manufactured by (EG &G ORTEC) with associated electronics and a computer-based multichannel analyzer.…”

The current work was carried out to characterize rock samples of mudstone, sand, and limestone collected at different depths from Northwestern Coast, Ras El-Hekma -Egypt. The samples were subjected to neutron activation analysis to determine the elemental composition and to better understand the geochemistry of the rocks. The abundance of 17 elements was determined. Bivariate and multivariate statistical analyzes were performed to investigate the origin of rocks and common geochemical characteristics (i.e., type, origin, geological history, major and trace composition, weathering, and alteration). The normalized results obtained showed that the abundances of Ca and Sr were significant compared to the corresponding values in the literature. The enrichment factor (EF) was calculated to obtain more information about the sources of the increased abundances of the metals. The results obtained can provide baseline data for the surveyed region and can be utilized by the government, policymakers, and interested parties for future research and development endeavors and planning.

“…A high-resolution gamma-ray spectrometer consists of a Canberra GC 6020 high purity germanium detector (HPGe) of efficiency 60 % coupled to 2026 Canberra spectroscopy amplifier and TRUMP 8K multichannel analyzer was used for detecting the natural radioactivity of samples. To decrease the background, the detector was surrounded by a 10 cm cylindrical lead shield with an inner layer of Cu to reduce gamma-ray scattering [36][37][38][39][40][41][42]. The efficiency calibration standard was International Atomic Energy Agency (IAEA) reference material RGU-1.…”

The Nubian sandstone aquifer's hydrogeophysical and natural radioactivity parameters at the Northwestern part of El Ain village, Sharq El Oweinat, Southwestern desert, Egypt are resolved using geophysical well logging and natural radioactivity techniques. The study aims to monitor the phenomenon of appearing an unusual high gamma-ray at a zone of high resistivity record. A nest of well logs is collected to assess how the phenomenon is widespread. Results of correlated well logs are clarified that this phenomenon at zone between 80 and 100 m and zone of 200 and 230m depth is noticed. The petro-physical properties are estimated from the recorded well logs. The results showed that the percentage of the average of effective porosity % varies between 20 and 28.2%, while average vary from 2 to 12.5 %, which indicates that the aquifer of Nubian Sandstone is classified as a clean aquifer. The natural radioactivities of the studied area in the rock samples were evaluated using high-purity germanium (HPGe) detector. The results indicated that the average value of Th-232 is (51.32 ±4.92%) Bq/kg, Ra-226 is (29.03 ± 4.68%) Bq/kg while the radioactivity concentration of K-40 exists only in one sample with low concentration.
