Abstract

Background, Supervision to ensure protection from radiation doses and safety for patients is very important so efforts are needed to optimize the application of radiation and medical exposure by applying the Diagnostic Reference Level (DRL). Monitoring and evaluation needs to be carried out at various health facilities that use radiation and then the evaluation results obtained are compared with the latest Indonesian Diagnostic Reference Level (IDRL) ​​so that their implementation becomes effective. Non-contrast abdominal MSCT examination at TK II Pelamonia Hospital Makassar is an examination that is often done with a visit frequency of 30% compared to other examinations, there are vital organs in it and this examination has never been evaluated for radiation doses.
