Introduction: Due to the characteristics and challenges of the pediatric population regarding radiation, the use of adequate doses of radiation is a duty of medical diagnostic centers. For this reason, the Dose Reference Levels (DRL) have been established in many countries to optimize and monitor the protocols of each institution. In Colombia there are no studies in this subject. Objective: To show the DRLs used in a university hospital of high complexity in the modalities of computed tomography (CT), radiography and fluoroscopy and to compare them with international standards. Methodology: Retrospective descriptive trial between 2018 and 2019. We analyzed dose length product (DLP) data for skull, chest, abdomen, and high-resolution chest CT (HRCT); and dose area product (DAP) for chest, abdomen, bone, and fluoroscopy radiography by age groups. Results: Data were collected for a total of 780 patients. 360 x-rays, 100 fluoroscopy and 320 tomography scans. Reference levels of radiation dose used in the hospital were found to be low compared to European guidelines of 2018 reference levels. DRLs are described for each study and age group. Conclusion: It was demonstrated that at the hospital where the study was conducted, reference levels of radiation in the pediatric population are low. This work can serve as a national reference.
