[ 1 ] - Evaluation of natural radioactivity of soil samples from different regions of Wassit governorate
The present paper measures natural radioactivity in different areas of Wassit governorate, using (HPGe) detector. Gamma spectrum analysis for each sample along with caululated specific activity show that the average concentrations of U-238, Th-232, and K-40 have been 19.420±4.7 Bq/kg, 18.487±5.05 Bq/kg, and 204.266±46.9 Bq/kg respectively, which is lower than the worldwide average value. While ...

[ 3 ] - Evaluation of Natural Radionuclide content in Nile River Sediments and Excess Lifetime Cancer Risk Associated with Gamma Radiation
Introduction: This Study has was carried out to measure and detect the natural occurred radionuclide content including 226Ra, 232Th and 40K in the Nile River sediments at various locations in Upper Egypt, from Aswan to El-Minya. Additionally, we determine the absorbed dose rate, the annual effective dose equivalent, and excess lifetime cancer risk also has been calculated. Material and Metho...
[ 4 ] - Assessment of Annual effective Dose for Different Age Groups based on Radon Concentrations in the Groundwater of Qassim, Saudi Arabia
Introduction: Given that the groundwater is a radon contaminated and used as a source for drinking water, then measuring the amount contamination is of high necessity. Material and Methods: The measurement was performed using RAD-7 detector. Results: The measured radon concentration values ranged 1.20-15.4...
[ 5 ] - Effects of Low Dose Gamma Ray on Some Hematological Parameters in Adult Rats
Introduction: The study aimed to find the low dose effect gamma ray on some hematological parameters in male albino rats obtained from the Mosul University, IRAQ, and also studied the radioprotective effect of black seed oil on the hematological parameters. Material and Methods: The system is made of 241Am as gamma source .The...
