The oil ash radioactive waste was generated from electrical power plants and it was presented great concern due to environmental impact. In this study oil ash was characterized from technical and radiological aspects. Oil ash average activity concentrations for 226 Ra, 232 Th, and 40 K were (1718 ± 85.9, 278.1 ± 13.9, and 136 ± 6.7) Bq/kg respectively, that were higher than the worldwide average. The average value of AED tot was (10.5 ± 0.5) mSv/y, which was higher than the dose limit of public. All the radiological parameters were higher than worldwide. The samples examined by XRF, and XRD. That contained economic elements as iron, vanadium, nickel.
