홈페이지논문 초록 (Abstract)
Radioactive Cs contamination has been widely dispersed by the nuclear disaster at the Fukushima Daiichi reactors in Japan on March 11, 2011 following a massive earthquake. To remove the contamination, the soil is collected and taken away by heavy equipment such as excavators, which has been shown to be inefficient because of the huge volume of radioactive waste that needs to be stored in an isolated location . In this study, the effect of thermal treatment of contaminated soil on the reductionof Cs was investigated. A high temperature above 1000 degrees C was effective in reducing the amount of Cs. Moreover, heat tr eatment under an inert gas atmosphere (Ar) was found to be more effecti ve than that under an air atmosphere over the whole temperature range.
