Abstract

Investigation is carried out that low-level liquid radioactive wastes which is consisted of long half-life nuclides such as cesium can be treated by Korean clinoptillolite as a kind of zeolites. Column operation using a activated clinoptillolite shows good results in terms of break-through curves and comparing to clinoptillolite classified at WARD in U.S, Korean clinoptillolite shows a tailing phenomena longer than that of WARD. The fixation quantity of radioactivity in Korea clinoptillolite is to be about $75{\mu}Ci/100g$ using a $2.5{\times}10^{-3}{\mu}Ci/ml$ solution.
