Calculation of Radionuclids Concentration in the Rising Dust Caused by the Movements of Cars and Wheels in Tikrit Streets

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).
