Abstract

Background: The radionuclide concentrations of 238U, 232Th, and 40K were measured in soil samples of some Governmental departments of Nasiriya city, at Thi Qar governorate Iraq. Materials and Methods: Using a NaI(Tl) detector, the specific activity of natural radionuclides in soil samples was evaluated. Results: The present investigation showed that the average values of specific activities (238U, 232Th, and 40K) were (5.37, 2.24, and 189.41 Bq/Kg), respectively. The averages values of the radiological hazards radium equivalent (Raeq), absorbed dose rate (Dγ), annual effective dose (AEDE), inside risk records (Hin), and external hazard index (Hex) were (23.16 Bq/kg, 11.96 nGy/h, 0.015 µSv/y, 0.059 µSv/y , 0.077, 0.063), respectively. Conclusion: According to these values, the results of the current study not exceeded the global permissible values of the natural radionuclides.
