초록

본 연구는 X선 검사실에서 환자와 함께 있어야 하는 상황에 의료종사자가 최소한의 선량을 받을 수 있는 위치를 알아보고자 한다. RQR 표준 선질을 설정하기 위해 가로, 세로 10 cm인 Al 1.5 mm의 부가여과판을 X선관에 부착하였다. 부가여과판은 Al 0.9 mm, Cu 0.3 mm, Ni 0.3 mm를 사용하였다. Acrylic Phantom은 각각 13.1 cm, 18.5 cm, 21.2 cm으로 설정하여 피사체 두께를 달리하였다. 그 결과 Al 0.9 mm를 사용하였을 때 Acrylic Phantom 13.1 cm의 anode low 50 cm 위치가 1853 nSv로 산란선의 영향을 가장 많이 받았고, Cu 0.3 mm를 사용하였을 때 Acylic Phantom 두께 13.1 cm의 anode low 150 cm 위치가 173 nSv로 산란선의 영향을 가장 적게 받았다. 본 연구로 X선관과 멀어질수록 공간산란선량이 감소되는 것을 확인하였다. 향후 산란선량의 피폭에 대한 더 많은 연구가 필요할 것으로 사료된다.

The purpose is to find out where medical workers can receive the minimum radiation does in clinical. In order to sett RQR standard quality of radiation, put a Al 1.5mm filter(row and column: 10 cm × 10 cm) on X-ray tube. Al 0.9 mm, Cu 0.3 mm, Ni 0.3 mm used as a filter. The Acrylic phantom were set to 13.1 cm, 18.5 cm, 21.1 cm. by the object thickness was different. As a results, when we use Al 0.9 mm, 1853 nSv was the highest numeral. It is a point of anode low 50 cm, when we use 13.1 cm Acrylic phantom. When we use Cu 0.3 mm, 173 nSv was the lowest numeral. It is a point of anode low 150 cm, when we use 13.1 cm Acrylic Phantom. In this study, it was confirmed that the spatial scattering dose decreased as the distance from the X-ray tube increased. It is considered that more studies on the exposure of scattered doses are needed in the future.
