의료기관의 방사선 차폐체의 차폐물질이 친환경소재로 변화되면서 기존 납의 일반된 차폐특성보다 차폐물질의 특성에 따른 방사선 방어가 중요한 요소로 대두되고 있다. 납과 유사한 차폐물질로 대표적인 텡스텐과 황산바륨은 친환경 소재로 시트나, 섬유 형태로 제작되어 사용되고 있다. 이테르븀은 치과 방사선영역에서 불투과성 물질로 불소화합물로 사용되었으며, 에너지대별 차폐특성과 기존 친환경소재의 차폐특성과 비교하여 x-선 차폐영역에서 차폐성능을 평가하고자 한다. 동일한 공정과 조건하에 세 종류의 차폐시트를 제작하여 실험하였으며, 의료방사선 영역에서 텅스텐과 약 5 % 차폐성능 차이가 나타났으며, 황산바륨보다 우수한 차폐성능을 보였다. 차폐시트의 단면 구조에서는 인자의 배열이 일정하지 못하는 큰 단점을 보였다. 따라서 산화이테르븀은 의료방사선 차폐물질로 충분한 가능성을 보였으며, 입자배열 구조와 입자크기 조절로 차폐성능을 향상시킬 수 있을 것으로 사료된다.

While the shielding substances of radiation shields in medical institutions are beginning to be replaced by environmentally friendly materials, radiation protection according to the shielding properties of environmentally friendly substances is becoming an important factor rather than the existing lead shielding properties. Tungsten and barium sulfate are representative shielding materials similar to lead, and are made in sheets or fiber form with eco-friendly materials. Ytterbium is an impermeable material used as a fluorine compound in the dental radiation field. This study aims to evaluate the shielding performance in the x-ray shielding area by comparing the shielding properties of ytterbium by energy band and that of existing eco-friendly materials. When three types of shielding sheets were fabricated and tested under the same process conditions, the shielding performance of the medical radiation area was about 5 % difference from tungsten. Furthermore, shielding performance was superior to barium sulfate. In the cross-sectional structure of the shielding sheet, there was a disadvantage that the arrangement of particles was not uniform. Ytterbium oxide showed sufficient potential as a medical radiation shielding material, and it is thought that it can improve the shielding performance by controlling the particle arrangement structure and particle size.
