원자력시설 및 동위원소 이용기관에서의 인체오염사고에 대비하여, 피부제염기준을 조사하였으며, 피부제염제의 개발을 위하여 실험용 쥐를 대상으로 Co-60 및 Cs-137에 대해 비눗물, EDTA 및 KAERI-CON의 제염효과를 비교하였으며, 가장 효율적인 제염방법을 제시하였다. 각 제염제의 제염실험결과 Co-60 보다 Cs-137에 대한 제염이 더 잘 이루어졌으며, 제염횟수의 증가에 따라 방사능잔류율도 급격히 낮아졌다. KAERI-CON은 Co-60의 경우 38-55%, Cs-137의 경우에는 44-50%까지 제염효율을 보임으로서 타 제염제보다 효과적임을 확인하였다.

In order to evaluate the effectiveness of some decontamination agents against skin contamination of $^{60}Co$ and $^{137}Cs$, the experiments were carried out in this study. In the experiments, pig skin was used instead of human skin , $^{60}CoC1_2$ and $^{137}CsCl$ were used the liquid sources of skin contamination. To examine the effectiveness of decontamination agents, skin decontamination was tried using soup, EDTA, KAERICON which was developed for decontamination of radionulides on the surface of building structure, and new decontamination agents such as IOCON, TRICON, and CHARCON, which were developed in this study. The absorption of radionuclides through the skin was evaluated by the gamma-tay detection on the surface of sample skin after radionuclides were penetrated into the skin during 16 hour soiling time. The results of this absorption experiment indicated that 11.5% and 3.2% of initial amounts of $^{137}Cs$ and $^{60}Co$, respectively, were panerated into the skin. In the experiment to remove the residual radioactivity fixed on the skin, KAERICON showed the decontamination rates up to 52.1%(decontamination factor of 2.1) and IOCON showed the equivalent decontamination rate (decontamination factor 1.9) for $^{137}Cs$. However, IOCON and CHARCON showed the poor decontamination rates of less than 20%(decontamination factor of 1.2) for $^{60}Co$, and KAERICON showed the poor decontamination rate (decontamination factor 1.1) for $^{60}Co$. For TRICON, the decontamination factors were 1.6 to 1.8 for $^{137}Cs$, and 1.0 to 1.2 for $^{60}Co$, respectively.
