Background: This study aimed to assess the equivalent and effective doses received by medical personnel during an interventional radiology procedure. Materials and Methods: Monte Carlo GATE was used to obtain the radiation doses. The protection provided by two protective garments was also investigated. Results: The effective doses at LLAT and RAO30 projections were found to contribute high doses to the medical personnel, with rates varying between 0.5 to 2.0 μSv. On the other hand, PA projection produced the lowest effective dose, between 0.04 to 0.6 μSv. In the simulation, a 0.5 mm-thick protective garment reduced the effective dose to more than three times. At LLAT and RAO30 projections, the effective dose with no protection increased with variations of 3 to 9 μSv, while PA projection increased the effective dose with variations of 1 to 3 μSv per procedure. Conclusion: A higher overall effective dose was observed for unshielded medical personnel. This work demonstrates the potential of Monte Carlo GATE in validating the doses received by medical personnel during interventional procedures. |
