Radionuclides Concentration and Radiological Risk in the Dust Rising in Some Streets of Diwaniyah City Due to the Movement of Wheels and Cars

This research aims to calculate the concentration of radionuclides in the dust risining samples, from some streets in the big side of Diwaniyah city due to the movement of wheels and cars using Gamma- rays spectroscopy of purity germanium detector (HpGe) with resolution of (2.3keV) for the energy of the 60Co (1.332 MeV). The 30 dust samples were collected from some of the streets in the big side of Diwaniyah, The average activity concentrations of 238U, 232Th, 40K and 137Cs in the samples were found to be (20.379284.5, 20.461394.5, 303.394417.4) Bqkg respectively. The calculated radium equivalent (Raeq) was (72.46534) Bq/kg, the absorbed dose rate (35.47465 nGy / h), the external annual effective dose of exposure rate AEDE_outwas (0.435 mSv/y), AEDE_in was (0.174024 mSv / y), the value of the external risk index (Hex) was 0.200328 and the internal risk index (Hin) was (0.314272).
