This study compared the spatial scattered dose distribution according to whether the recently developed radiation shielding is used or not in order to understand the spatial scattered dose distribution of C-arm. The horizontal side distribution increased by 30° in the interval of the radius 50 cm on the height of 95 cm based on the head of the patient, and it was measured by increasing 30° with the interval of 50 cm in the vertical side of each horizontal side. In the same method, the radiation shielding was installed and measured. The result of measurement shows that the horizontal side of 50 cm distance was 0°, 90° and 180°, was 1.77±0.12, 1.90±0.13, 2.12±0.14, and 2.69±0.15 mSv/h in the 270° direction, and was 1.59±0.12, 0.99±0.09, 1.47±0.11, and 1.37±0.11 mSv/h after the use of the radiation shielding. In addition, the vertical distribution in horizontal direction 90° with 50 cm distance was 30°, 60°, 120°, was 3.85±0.18, 9.15±0.28, 10.82±0.31, and 5.40±0.22 mSv/h in 150°, and was 2.03±0.13, 4.32±0.19, 2.76±0.16, and 1.92±0.13 mSv/h mR/h after the use of the radiation shielding. Both direction showed decrease according to the use of the radiation shielding. Therefore, radiation related workers who work in operating rooms should recognize the spatial scattered dose distribution exactly and need to try to prevent the risk of radiation exposure with proper protective measures.
