abstract={The activity concentrations of naturally occurring radionuclides <SUP>226</SUP>Ra, <SUP>232</SUP>Th and <SUP>40</SUP>K in soil samples collected from Fuel Fabrication Facility in Al-Tuwaitha nuclear site were measured by using a high resolution gamma spectrometry system via High Purity Germanium (HPGe) Detector with a relative efficiency of (>40%) and resolution (&lt;1.8keV) at energy of (1.33MeV) for <SUP>60</SUP>Co. The average activity concentrations of <SUP>226</SUP>Ra, <SUP>232</SUP>Th and <SUP>40</SUP>K in soil samples were found to be 15.78¡À1.16, 14.09¡À1.33 and 306.42¡À18.1 Bqkg<SUP>-1</SUP>, respectively. The results obtained for the corresponding radionuclides are lower than the worldwide average values of 35, 30, and 400 Bqkg<SUP>-1</SUP>, respectively. The average absorbed dose rate in air (D¦Ã), the average radium equivalent activity (Ra<SUB>eq</SUB>) and the average external hazard index (H<SUB>ex</SUB>) were determined as 28.90¡À2.12 nGyh<SUP>-1</SUP>, 59.52¡À4.45 Bqkg<SUP>-1</SUP> and 0.16¡À0.012, respectively, which are below the permissible limit.},
