evaluation of radiation exposure of urology surgeons and radiology personnel during fluoroscopy guided surgeries at shahid faghihi hospital in shiraz

Abstract

Background & Objective: Long term exposure to ionizing radiation and its complication have always been concerned by medical physicists. Some previous studies have shown that radiation dose to urology surgeons and involved personnel during mini C-arm fluoroscopy guided surgeries exceeds the secure threshold in some cases. In this study, we intend to evaluate the radiation exposure of urology surgeons and radiology personnel and compare these results to the standard thresholds. Material & Methods: Four urology surgeons, eight residents and eight radiology personnel underwent radiation dosimetry on five different organs during three months. Mentioned surgeons used mini C-arm fluoroscopy and TLD-100s were used for dosimetry.     Results: Calculated mean for accumulative radiation exposure for Urology surgeons, residents and radiology personnel are 174, 198 and 184 milirem, respectively. The absorbed dose for different organs were calculated in descending order at dominant hand, thyroid, subdominant hand, Gonads and Chest wall.  Conclusion: According to the results, radiation exposure during fluoroscopy guided surgeries has not exceeded the standard threshold defined by National Council on Radiation Protection and Measurement (NCRP).
