چکیده
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 the average value of radium equivalent, absorbed dose, indoor and outdoor annual effective dose, activity index, and internal and external hazard index for each sample have been found to be 85.182 bq/kg, 39.962 ngy/h, 0.196 msv/y, 0.049 msv/y, 0.374, 0.313, 0.309, and 0.230 respectively, all of them are lower than the permissibility limit value.

متن کاملNatural radioactivity assessment in soil samples from Kirkuk city of Iraq using HPGe detector
Background: Inspection of the level of radioactivity from radionuclides in soil is important for the assessment of the exposure to natural radiation. Materials and Methods: Ten samples from soil were collected from different sites of Kirkuk-IRAQ and the level of natural radioactivity was measured using gamma-ray spectrometry based on a high purity germanium (HPGe) detector. Results: It was foun...
متن کاملEstimation of Natural Radioactivity and Radiation Exposure in Environmental Soil Samples of Golestan, Iran
Introduction: Considering the risk of radiation, the measurement of the natural radiation sources seems to be necessary. In this study, the concentrations of the natural radionuclides, namely 226Ra, 232Th, and 40K, were measured in the soil samples taken from different locations of Golestan, Iran. The measurement results can also be used as a baseline to evaluate the impact of non-nuclear activ...
