Objective: One of the surgical teams that uses fluoroscopy most frequently during operations is the orthopedics and traumatology team. This study aims to indicate that the radiation dose decreases with distance and to stimulate awareness of radiation protection of the team through real-time measurements during fluoroscopy. Methods: The study was carried out in the operating rooms of orthopedics and traumatology clinic between 1.08.2025 and 31.08.2025. The radiation dose emitted from the fluoroscopy during imaging in both AP and LAT positions of the X-ray tube for each case was measured with a Geiger-Müller detector at defined distances inside the room, and recorded in the data form. Results: Real-time measurements were performed during 62 operations. Of these 62 operations, 15 were upper extremity, 39 were lower extremity and 8 were pelvis/acetabulum surgeries. A total of 3062 imaging were recorded in 62 cases, with a mean of 49 imaging per case, and a total of 2051.54 seconds of imaging time, with a mean of 33.09 seconds per case. The measurements taken at A1, A5 and L1, L5 points which are closer to the primary source, were statistically significantly higher than the measurements taken at further distances, p<0.05. Conclusion: In addition to annual and periodic radiation area monitoring of operating rooms at our institution, this study has increased awareness of the orthopedics and traumatology team through detailed, real-time measurements. The results underlined once again the importance and effectiveness of applying the distance rule as well as the use of personal shielding equipment for radiation protection.
