Abstract: | Levels of naturally occurring radioactivity in sediment samples of Beni Haroun dam have been investigated. The activity concentrations of 238U and 232Th decay chains and 40K primordial radionuclide have been measured using high-resolution HPGe detector. Activity concentrations of 226Ra, 232Th, and 40K radionuclides were found in the ranges 9–66, 14–37, and 177–288 Bq/kg with the mean values 24.67, 25.98, and 208.10 Bq/kg, respectively. Radiological hazard parameters were estimated based on the activity concentrations for 226Ra, 232Th, and 40K to find out any radiation hazard associated with the sediments. Correlation studies between pairs of radionuclides were performed and discussed, and the obtained results are compared with international recommended values. |
