Tunnel were the inverse analysis based on the crown displacement calculated based on the generation of the result 63.80mm crown displacement measurement result. Three-dimensional inverse analysis up to the crown displacement was 60.7mm has occurred, which was considered similar to a two-dimensional inverse analysis 63.6mm.*

고용량옥소치료시수평면, 수직면, 방위각에따라3차원적으로방출되는공간선량률을측정하였다. 정확한측정을위해기하학적구조의알루미늄틀을제작하여100 cm 거리에서, 높이(5 측정점), 방위각(8 측정점), 시간적간격(6 측정점)을각각나누어서분석하였다. 수직면상공간선량률분포는131I을경구투여24 시간후환자로부터거리100 cm , 높이100 cm 지점에서환자군평균71.85 µSv/h로가장높았다. 수분섭취를통한공간선량률감쇠정도를두그룹으로나누어실험하였다. 131I을경구투여24시간뒤거리100 cm, 높이100 cm에서공간선량률분포가A 실험군은44.9 µSv/h이고B 실험군은100.28 µSv/h이다. A 실험군이B 실험군과비교하여고용량옥소치료시수분섭취정도에따라약53 %의피폭경감효과를확인하였다.
