Fluoroscopy-guided endoscopic procedures (FGEPs) are rapidly gaining popularity in the field of gastroenterology. Radiation is a well-known health hazard. Gastroenterologists who perform FGEPs are required to protect themselves, patients, as well as nurses and radiologists engaged in examinations from radiation exposure.

To achieve this, all gastroenterologists must first understand and adhere to the International Commission on Radiological Protection Publication.

In particular, it is necessary to understand the three principles of radiation protection (Justification, Optimization, and Dose Limits), the ALARA (As Low As Reasonably Achievable) principle, and the Diagnostic Reference Levels (DRLs) according to them.

This review will mainly explain the three principles of radiation exposure protection, DRLs, and occupational radiological protection in interventional procedures while introducing related findings.

Gastroenterologists must gain knowledge of radiation exposure protection and keep it updated.
