N2 - Medical personnel working with ionizing radiation are exposed to significant radiation doses. Previously published studies reported increased incidence of induced cancer and cataracts among radiation workers in medical and industrial premises due to exposure to ionizing radiation. Therefore, an assessment of occupational exposure is recommended. The purpose of this study is to estimate the radiation risk caused by staff exposure and ambient exposures during diagnostic radiography. The study involved 46 staff members: 38 technologists, 8 Radiologists and 22 patients: 11 undergoing conventional radiology and 11 undergoing fluoroscopic radiology. Occupational and ambient doses were measured using calibrated optical stimulating-luminescent dosimeters (OSL) (Al2O3:C). These badges were read using an automatic OSL reader. Patients’ doses were calculated form the reading of the x-ray machines. Calculating the dose parameters for patients, the mean and standard deviation (SD) of the kVp, mAs, and patient doses in terms of Dose Area Product (DAP)were 113.1 ± 16.2, 7.5 ± 11.65, and 869.6, respectively. The mean and range of the annual effective dose (mSv) for technologists was (0.6 ± 0.36) (0–2.11). The mean and range of effective dose (mSv) for Radiologists were (0.48 ± 0.19) (0.17–0.74). The occupational exposure in this study showed that radiology technologists and radiologists are exposed to a low dose according to the current workload. The staff dose reported in this study is lower than those available in most previous studies.
