A. Dyer et al., The use of natural zeolites for radioactive waste treatment: Studies on leaching from zeolite/cement composites, J RAD NUCL, 243(3), 2000, pp. 839-841
Samples of the natural zeolites chabazite, clinoptilolite and a clinoptilol
ite-rich tuff, were loaded with the isotope Cs-137. Composites of these lab
eled materials were made with cement and blast furnace slag. Standard leach
ing experiments were carried out with synthetic sea, ground and "pond" wate
rs, as well as distilled water. Rates of leaching were calculated and compa
red to similar systems.
