초록

본 연구는 유리 선량계를 이용한 진단용 X선 장치 선량 및 선질의 입사표면선량 값과 선질 계수에 의한 계산 측정법을 바탕으로 비교 평가하여 의료 피폭 선량에 대해 연구하였다. 실제 측정에 의한 ESDs 값이 Mori에 의한 NDD-M 법에서 가장 큰 차이를 보였으며, Edmonds에 의한 계산법이 가장 적은 차이를 보였다. 또한 정류 방식에 따른 실 측정과 선량 계산법 차이는 삼상 정류 방식, 단상 정류 방식, 인버터 방식으로 차이가 적게 나타났다. 본 연구 결과는 향후 진단용 X-선 촬영 장치의 사용에 있어 환자의 피폭 선량을 예측하고 검사 조건을 조절하여 의료 피폭 선량을 절감할 수 있을 것이다.

The aim of this study is to compare radiation dose in diagnostic X-ray radiography and calculated by different mathematical equation. The result of ESDs direct measurement and that calculated by Mori NDD-M shows the biggest difference. On the other hand, equation by Edmonds shows the lowest difference of ESDs. Also, Rectification due to the difference between direct dose measurement and calculation method commutated three-phase, single phase and inverter type, show less difference in the drive way. In conclusion, this study can be helpful for expecting radiation dose-exposure and control exposure parameters for the diagnostic x-ray radiography.
