Abstract
Gamma radiation damage in zeolite- 13X is studied with special reference to the Cs+ uptake by the zeolite. Prolonged exposure to a 5 kCi 60Co-γ source with a dose rate of 4.5 k Gyh−1 does not alter the cation exchange capacity of the zeolite. Structural effects consequent to γ-irradiation are examined by the X-ray diffraction, i.r. and surface area measurements. The data support the view of displacement of exchangeable cations as also the framework atoms from their normal locations. EPR measurements suggest the formation of paramagnetic centre in the structure. A 3 % weight loss and release of hydrogen subsequent to γ-irradiation (∼840 h) is attributed to the radiolysis of zeolite water.Keywords
