In order to minimize patient entrance surface dose (ESD), this study aims to determine the diagnostic reference levels (DRLs) for routine radiography in Arrazi Hospital (ARH) at the Mohammed VI University Hospital Centre (Med VI UHC) in Marrakech, Morocco. A total of 1170 radiography examinations (RE) were included. They underwent 13 separate projections in the adult radiology department of the Marrakech-Safi region teaching hospital. The X-ray tube's dose area product (DAP) was used to figure out the patient's entrance skin dose (ESD) for the cervical spine anterior-posterior (AP), cervical spine lateral (LAT), lumbar spine AP/LAT, abdomen AP, pelvis AP, shoulder AP, knee AP/ LAT, skull AP/ LAT, and the chest AP. The 75th percentiles with respect to ESD for cervical spine AP/LAT, lumbar spine AP/LAT, abdomen AP, pelvis AP, shoulder AP, knee AP/LAT, skull AP/LAT, and chest AP were 2.1 mGy/1.8 mGy, 3.7 mGy/5.9 mGy, 1.9 mGy, 2.35 mGy, 1.5 mGy, 0.7 mGy/0.65 mGy, 2.9 mGy/2.7 mGy, and 0.25 mGy, respectively. We compared our DRL results with those of other countries. Although the estimated DRLs are encouraging, significant efforts are needed to reduce them, particularly for shoulder, knee, and skull X-rays.
