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 found that the specific activity ranged from 27.4 to 57.0 Bq kg−1 for 226Ra, from 11.0 to 25.4 Bq kg−1 for 232Th, and from 207.4 to 516.0 Bq kg−1 for 40K. The results have been compared with the average values worldwide. The hazard indices have also been calculated. In general certain average values were found to be lower than the world average values; these included the average value of the radium equivalent activity (Raeq), the absorbed gamma dose rate (D), the external and internal hazard Hex and Hin, the gamma radiation representative level Index (Iγ) and the outdoor and indoor annual effective dose rate (AEDE) Conclusion: In general there are no harmful radiations effects posed to the population who live in the study area; however there are some spots which have values higher than the internationally allowable values.
Keywords: Natural radioactivity, soil contamination, activity concentrations, HPGe detector, Radiation hazard indices.
