Abstract

Simulation of 137Cs radioactive decay to 137Ba by an equiatomic substitution of Cs with Ba in a 30 Na2O, 10 Cs2O, 10 Al2O3, 10 Fe2O3, 40 P2O5 (mol%) glass was studied by X-ray diffraction, scanning electron microscopy, Fourier Transform Infrared spectroscopy, Mössbauer spectroscopy, and measurement of hydrolytic durability. Gradual Ba substitution for Cs yielded minor changes in the structural network but did not offer appreciable effect on phase composition and hydrolytic durability of the glasses.
