Abstract

In this study, we investigated the conditions used in setting the recommendation level of general radiography diagnostic reference and tried to evaluate the effective dose and biological evaluation using PCXMC v2.0 program. As a result based on the effective dose of male in ICRP 60, the highest Pelvis AP was 0.794 mSv. The lowest Chest PA was 0.050 mSv. In the case of ICRP 103, the highest T-Spine AP was 0.906 mSv The lowest Chest PA was 0.052 mSv. For 40 years old male and female adults, effective doses of general radiography were evaluated and even if the medical exposures are not subject to the limit of dose, efforts should be made to reduce the medical exposures of the people by keeping the dose below the recommended amount in order to minimize the probable effect of radiation hazard.

본 연구에서는 국가에서 권고하고 있는 일발촬영 진단참고준위 설정에 사용된 조건을 조사하여 PCXMC v2.0 프로그램을 이용하여 유효선량을 측정하고 생물학적 평가를 해보고자 한다. 그 결과 ICRP 60에서 유효선량은 가장 높은 Pelvis AP는 0.794 mSv 가장 낮은 Chest PA는 0.050 mSv이었다. ICRP 103에서는 남성이 가장 높은 T-Spine AP는 0.733 mSv 가장 낮은 Chest PA는 0.057 mSv, 여성은 가장 높은 T-Spine AP는 0.906 mSv 가장 낮은 Chest PA는 0.052 mSv이었다. 남녀 성인 40세 기준으로 일반촬영별 유효선량을 평가 해 보았고, 선량한도의 제한을 받지 않는 의료피폭이라도 방사선위해의 확률적 영향을 최소화하기 위해서 선량을 권고량 이하로 유지하여 국민의 의료피폭을 줄이기 위해 노력이 필요할 것으로 사료된다.
