Abstract
Abstract
Activity concentrations of primordial radionuclides in soil samples collected from the Al-Lajjun region were measured using a γ-ray spectrometry system using pure germanium (HPGe) detector in a low background configuration. The mean activity concentrations for 40K, 226Ra, 232Th, 238U, 235U, and 241Am at different locations of Al-Lajjun/Karak/Jordan were found to be in the range of 12–560, 234–6037, 4.3–28.4, 459-54147, 43-3656, 43-3332 Bq/Kg, respectively. The obtained values of some samples are much greater than the world average values except for 40K and 232Th. Radium equivalent activity, absorbed dose rate, and annual effective dose equivalent were calculated for assessing the assessment of radiological risk. The external hazard value (Hex) is between 0.638 and 16.316. In the present study. 238U concentration is much higher than the acceptable value reported by UNSCEAR-2000.
