The potential uses of zeolites in the treatment of radioactive wastes
may be conditioned to the physico-chemical properties of these materia
ls. This work compares the Co sorption behavior of zeolite 4A and radi
ation treated zeolite 4A. Sorption experiments were performed with sol
utions containing labeled cobalt. No radiation effect (100 Mrad) in th
e zeolite structure or in the Co sorption behavior was found.
