Abstract: The mean objective in diagnostic radiology is to in provide high quality diagnostic image while keeping the patients and workers dose in the lower limit according to ALARA principle, (Maria Lucia Nana et al 2009). To optimize the practice of diagnostic radiology, adequate quality assurance (QA) program should be in place.18 hospitals with 18 x-ray units distributed in Khartoum state were evaluated in this study. Each x-ray unit was tested for Kvp and time Reproducibility, accuracy of Kvp and time, mAs linearity, and coincidence between light beam and radiation beam. The dark rooms were also evaluated to assess the fog level. CONNY II QC Dosimeter made by PTW company were use to for this study. The analysis of the results showed that two out of eighteen unit had a problem in mAs linearity, also two out of eighteen unit had a problem in kVp accuracy and one had a problem in kVp reproducibility. three devices have defects concerning adaptation with optical field and radiation field. More than 50 % of the darkrooms had a problem in fog level, time accuracy and time reproducibility were in the acceptable limit. The quality control of the radiological devices should be performed periodically and regularly and the defects of the devices should be removed in order to be assured of the appropriate function of the devices. many of these machines need service because of lack of implementing the quality control program regularly, which indicates that the quality control programs should be extended regularly. because the dark rooms is very important place specially in conventional radiology department like in Sudan so it need to periodic review to monitor the fog.
