Languages of publication
In this paper, the determination of specific activity concentrations in ten soil samples collected from the antiquity's area of the archaeological of Ur city, were carried out using HPGe scintillation detector. The results of measurements have shown that the specific activity, for 238U varied from (16.520 Bq/kg) to (30.620 Bq/kg), with average value (24.730 ±4.05 Bq/kg), the specific activity of Th-232 was varied from (18.730 Bq/kg) to (31.670 Bq/kg), with average value of (25.098 ±3.41 Bq/kg), while the specific activity of K-40 was varied from (123.340 Bq/kg) to (261.480 Bq/kg), with average value of (189.767 ±39.47 Bq/kg). All soil samples of the archaeology of Ur city were found to be lower than the recommended values given by (UNSCEAR, 2000). In order to asses the radiological hazards of the radioactivity in soil samples of the archaeological of Babylon city, (Raeq, DƔ, AEDin, AEDout, EAD, Iɣ,Iα, Hin and Hex) have been calculated, and all the obtained results were found lower than the allowed limits given by (UNSCEAR, 2000).
