摘要：

In this study, we report on the activity concentrations of238U,232Th,40K, and137Cs in 50 soil samples of Bethlehem Province, West Bank, Palestine. Gamma-ray spectroscopy was employed to perform the measurements using an HPGe detector. On one hand, the activity concentrations of natural radionuclides were found to vary from 12.7 to 122.3 Bq kg-1 with an average value of 41.4 Bq kg-1 for238U, from 2.0 to 32.2 Bq kg-1 with an average value of 19.5 Bq kg-1 for232Th, and from 12.0 to 183.8 Bq kg-1 with an average value of 113.3 Bq kg-1 for40K. On the other hand, the activity concentrations of the artificial137Cs radionuclide were found between 1.0 and 12.2 Bq kg-1, with an average value of 2.8 Bq kg-1. The variations of the assessed radiological hazard parameters indices Raeq, Dr, Hex, and Iγ of natural radionuclides were found to be as follows: 16-148, 7-65, 0.04-0.4, and 0.11-1.00, respectively. The results were found to be comparable to or lower than similar reported data worldwide. Accordingly, the investigated soil zones can be considered to have normal levels of natural background radiation. © TÜBİTAK.
