Abstract

It is intended to evaluate the performance of the shield after manufacturing a shield with cheap and eco-friendly iron oxide and alumina instead of lead, which is a radiation shielding material. After manufacturing the shield by mixing iron oxide and alumina with gypsum, the performance is evaluated by comparing it with gypsum board and lead apron using an X-ray tube. As a result of the experiment, the shielding performance of alumina was lower than that of the gypsum board, and when 50% of alumina was contained, the shielding performance was similar to that of the gypsum board. Iron oxide became similar to the shielding performance of lead apron when it contained about 75%. A shielding material using alumina shows shielding performance similar to that of gypsum, so it is not suitable as a substitute for lead. However, since iron oxide exhibits similar shielding performance to lead, it can be used as an X-ray shielding material to replace lead in the future, so further research is needed.

방사선 차폐 물질인 납을 대신하여 싸고 친환경적인 산화철, 알루미나로 차폐체를 제작 후 차폐체의 성능을 평가하고자 한다. 산화철과 알루미나 각각 석고와 혼합하여 차폐체를 제작 이후 X-ray Tube를 이용하여 석고보드, 납복과 비교하여 성능을 평가한다. 관전압에 변화를 주며 실험한 결과 알루미나의 차폐 성능은 석고보드보다 차폐 성능이 떨어졌으며 50%의 알루미나가 함유되었을 때 석고보드와 차폐 성능이 비슷하였다. 산화철은 약 75%가 함유되었을 때 납복의 차폐 성능과 비슷해졌다. 알루미나를 이용한 차폐체는 석고와 비슷한 차폐 성능을 보여줘 납 대체물질로 적합하지는 않다. 하지만 산화철은 납복과 비슷한 차폐 성능을 나타내어 향후 납을 대체하는 X선 차폐 물질로 활용이 가능하기에 추가 연구가 필요하다.
