Abstract: The aim of this study is to calculate the concentration of radionuclides in the dust rising from the streets of Tikrit as a result of the movement of cars and wheels by using the Gama ray source of 60Co and the high-purity Germanium (HpGe) detector with 2.6 kV for energy (1332 MeV) 60Co.50 dust samples from the streets of Tikrit were collected The results shows a concentration of 238U to be (5.2017 2.28 Bk/kg), the 232Th was (11.1702 3.34 Bk/kg), 137Cs was (10.8843 3.3 Bq / Kg) and Radium Equivalent Raeq was (49.448 Bq / Kg), Absorbed Dose (24.09311 nGy / h), External and Internal Hazard Indices was (Hex) (0.0337 mSv / y) and (Hin) was (0.1349 mSv/y), Annual Effective Dose Equivalent (AEDE) and Gamma Radiation Level Index (I) was (0.38444).
