Abstract | 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 $30^{\circ}$ 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 $30^{\circ}$ 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 $0^{\circ}$, $90^{\circ}$ and $180^{\circ}$, was $1.77{\pm}0.12$, $1.90{\pm}0.13$, $2.12{\pm}0.14$, and $2.69{\pm}0.15mSv/h$ in the $270^{\circ}$ direction, and was $1.59{\pm}0.12$, $0.99{\pm}0.09$, $1.47{\pm}0.11$, and $1.37{\pm}0.11mSv/h$ after the use of the radiation shielding. In addition, the vertical distribution in horizontal direction $90^{\circ}$ with 50 cm distance was $30^{\circ}$, $60^{\circ}$, $120^{\circ}$, was $3.85{\pm}0.18$, $9.15{\pm}0.28$, $10.82{\pm}0.31$, and $5.40{\pm}0.22mSv/h$ in $150^{\circ}$, and was $2.03{\pm}0.13$, $4.32{\pm}0.19$, $2.76{\pm}0.16$, and $1.92{\pm}0.13mSv/h\;mR/h$ 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. 본 연구는 C-arm의 공간산란선량분포를 파악해 보고자, 최근에 개발된 방사선 차폐기의 사용 유무에 따른 공간산란선량분포를 비교하였다. 수평면 분포는 95 cm 높이에서 환자 머리를 기준으로 반경 50 cm 간격으로 $30^{\circ}$씩 증가하였고, 각 수평면의 수직면 내에서 반경 50 cm 간격으로 $30^{\circ}$씩 증가하며 측정하였다. 동일한 방법으로 방사선 차폐기를 설치 후 측정하였다. 측정결과 50 cm 거리 수평면은 $0^{\circ}$, $90^{\circ}$, $180^{\circ}$ 그리고 $270^{\circ}$ 방향에서 $1.77{\pm}0.12$, $1.90{\pm}0.13$, $2.12{\pm}0.14$, 그리고 $2.69{\pm}0.15mSv/h$, 방사선 차폐기 사용 후 $1.59{\pm}0.12$, $0.99{\pm}0.09$, $1.47{\pm}0.11$, 그리고 $1.37{\pm}0.11mSv/h$로 나타났다. 또한, 50 cm 거리 수평 방향 $90^{\circ}$의 수직 분포는 $30^{\circ}$, $60^{\circ}$, $120^{\circ}$ 그리고 $150^{\circ}$에서 $3.85{\pm}0.18$, $9.15{\pm}0.28$, $10.82{\pm}0.31$, 그리고 $5.40{\pm}0.22mSv/h$, 방사선 차폐기 사용 후 각 각 $2.03{\pm}0.13$, $4.32{\pm}0.19$, $2.76{\pm}0.16$, 그리고 $1.92{\pm}0.13mSv/h$이었다. 방사선 차폐기 사용에 따라 각 방향 모두에서 감소하였다. 따라서 수술실에 근무하는 방사선관계종사자는 공간산란선량 분포를 정확히 인지하고 적절한 방호 대책으로 피폭의 위해를 방지하는 노력이 필요하다고 사료된다. |

AbstractList | 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 $30^{\circ}$ 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 $30^{\circ}$ 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 $0^{\circ}$, $90^{\circ}$ and $180^{\circ}$, was $1.77{\pm}0.12$, $1.90{\pm}0.13$, $2.12{\pm}0.14$, and $2.69{\pm}0.15mSv/h$ in the $270^{\circ}$ direction, and was $1.59{\pm}0.12$, $0.99{\pm}0.09$, $1.47{\pm}0.11$, and $1.37{\pm}0.11mSv/h$ after the use of the radiation shielding. In addition, the vertical distribution in horizontal direction $90^{\circ}$ with 50 cm distance was $30^{\circ}$, $60^{\circ}$, $120^{\circ}$, was $3.85{\pm}0.18$, $9.15{\pm}0.28$, $10.82{\pm}0.31$, and $5.40{\pm}0.22mSv/h$ in $150^{\circ}$, and was $2.03{\pm}0.13$, $4.32{\pm}0.19$, $2.76{\pm}0.16$, and $1.92{\pm}0.13mSv/h\;mR/h$ 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. 본 연구는 C-arm의 공간산란선량분포를 파악해 보고자, 최근에 개발된 방사선 차폐기의 사용 유무에 따른 공간산란선량분포를 비교하였다. 수평면 분포는 95 cm 높이에서 환자 머리를 기준으로 반경 50 cm 간격으로 $30^{\circ}$씩 증가하였고, 각 수평면의 수직면 내에서 반경 50 cm 간격으로 $30^{\circ}$씩 증가하며 측정하였다. 동일한 방법으로 방사선 차폐기를 설치 후 측정하였다. 측정결과 50 cm 거리 수평면은 $0^{\circ}$, $90^{\circ}$, $180^{\circ}$ 그리고 $270^{\circ}$ 방향에서 $1.77{\pm}0.12$, $1.90{\pm}0.13$, $2.12{\pm}0.14$, 그리고 $2.69{\pm}0.15mSv/h$, 방사선 차폐기 사용 후 $1.59{\pm}0.12$, $0.99{\pm}0.09$, $1.47{\pm}0.11$, 그리고 $1.37{\pm}0.11mSv/h$로 나타났다. 또한, 50 cm 거리 수평 방향 $90^{\circ}$의 수직 분포는 $30^{\circ}$, $60^{\circ}$, $120^{\circ}$ 그리고 $150^{\circ}$에서 $3.85{\pm}0.18$, $9.15{\pm}0.28$, $10.82{\pm}0.31$, 그리고 $5.40{\pm}0.22mSv/h$, 방사선 차폐기 사용 후 각 각 $2.03{\pm}0.13$, $4.32{\pm}0.19$, $2.76{\pm}0.16$, 그리고 $1.92{\pm}0.13mSv/h$이었다. 방사선 차폐기 사용에 따라 각 방향 모두에서 감소하였다. 따라서 수술실에 근무하는 방사선관계종사자는 공간산란선량 분포를 정확히 인지하고 적절한 방호 대책으로 피폭의 위해를 방지하는 노력이 필요하다고 사료된다. 본 연구는 C-arm의 공간산란선량분포를 파악해 보고자, 최근에 개발된 방사선 차폐기의 사용 유무에 따른 공간산란선량분포를 비교하였다. 수평면 분포는 95 cm 높이에서 환자 머리를 기준으로 반경 50 cm 간격으로 30°씩 증가하였고, 각 수평면의 수직면 내에서 반경 50 cm 간격으로 30°씩 증가하며 측정하였다. 동일한 방법으로 방사선 차폐기를 설치 후 측정하였다. 측정결과 50 cm 거리 수평면은 0°, 90°, 180° 그리고 270° 방향에서 1.77±0.12, 1.90±0.13, 2.12±0.14, 그리고2.69±0.15mSv/h, 방사선 차폐기 사용 후 1.59±0.12, 0.99±0.09, 1.47±0.11, 그리고 1.37±0.11mSv/h로 나타났다. 또한, 50 cm 거리 수평 방향 90°의 수직 분포는 30°, 60°, 120° 그리고 150°에서 3.85±0.18, 9.15±0.28, 10.82±0.31, 그리고 5.40±0.22mSv/h, 방사선 차폐기 사용 후 각 각 2.03±0.13, 4.32±0.19, 2.76±0.16, 그리고 1.92±0.13mSv/h이었다. 방사선 차폐기 사용에 따라 각 방향 모두에서 감소하였다. 따라서 수술실에 근무하는 방사선관계종사자는 공간산란선량 분포를 정확히 인지하고 적절한 방호 대책으로 피폭의 위해를 방지하는 노력이 필요하다고 사료된다 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.
