The present study discusses the effect of gamma-irradiation on Cs+-exchanged X and A zeolites. The incorporation of Cs+ ions into A and X zeolites was performed using three different cesium salts (chloride, nitrate or acetate). Cs+ ions immobilized into the vitrified zeolites by thermal treatment are located in different sites of the zeolite networks. It is found that gamma-irradiation favors cesium retention depending on the cesium precursor salt used in the cationic exchange step.
本研究探讨了γ辐射对铯离子交换的X型和A型沸石的影响。使用三种不同的铯盐（氯化物、硝酸盐或醋酸盐）将铯离子引入A型和X型沸石中。通过热处理固定在玻璃化沸石中的铯离子位于沸石网络的不同位置。研究发现，γ辐射有利于铯的保留，这取决于阳离子交换步骤中使用的铯前驱体盐。
