Description
The widespread adoption of C-arm fluoroscopy has significantly optimized minimally invasive spinal and orthopaedic surgery by reducing operative morbidity, its frequent intraoperative application necessitates rigorous monitoring and safety protocols to mitigate the cumulative health risks posed by scatter radiation exposure to surgical personnel. Therefore, this study aims to evaluate occupational radiation exposure among radiographers involved in C-arm–guided spinal procedures and to increase awareness of radiation safety practices in routine clinical settings. A prospective cross-sectional study was conducted over a three-month period involving radiographers participating in spinal procedures requiring C-arm fluoroscopy. Occupational radiation exposure was measured using thermoluminescent dosimeters (TLDs) worn at multiple anatomical sites, including the eye level, thyroid, chest, gonadal region, and posterior trunk, with an additional control dosimeter. Radiographers adhered to standard radiation protection measures throughout all procedures. Procedure-related parameters, including operative duration and fluoroscopy exposure time, were systematically recorded. A statistically significant correlation was found between fluoroscopy exposure time and radiation dose in peripheral body regions, notably the wrists and upper body sites closest to the radiation source. The total radiation dose ranged from 0.18 mSv to 2.31 mSv depending on the dosimetry site. Radiation exposure was within acceptable limits in all regions, including the left wrist (r=0.731, p<0.01) and right wrist (r=0.59, p<0.05). Radiographers performing C-arm–guided spinal procedures are exposed to occupational radiation. Although measured doses were within recommended safety limits, repeated low-level exposure may still present long-term risks. Therefore, consistent dose monitoring, proper use of protective equipment, reduced fluoroscopy time, and continuous radiation safety training are essential to maintain occupational safety.
