In the present work, we have measured specific activity concentrations in ten tap water samples for selected regions in Thi-Qar governorate by using high purity germanium (HPGe) detector. The results have shown that, the specific activity, for 238U was ranged from (0.65±0.8 Bq/kg) in AL- Nasir region to (1.32±0.7.8 Bq/kg) in AL-Refai region, for 232Th the specific activity was ranged from (0.120±0.34 Bq/kg) in AL-Garraf region to (0.980±0.99 Bq/kg) in AL- Dwaya region, for 40K the specific activity was ranged from (13.33±3.6 Bq/kg) in AL-Nasir region to (38.54±6.2 Bq/kg) in (AL-Garraf) region, with an average values of (0.933±0.16 Bq/kg), (0.737±0.17 Bq/kg), (24.451±7.5Bq/kg), for 238U, 232Th and 40K, respectively. In order to asses the radiological hazards of the radioactivity in tap water, we have been calculated the parameters (Raeq , DƔ, AEDin , AEDout , EAD , Iɣ , Hin and Hex).
