摘要：
In the present work, gamma irradiation effects on lead-free Bi2O3-B2O3-SiO2 heavy metal oxide glasses are investigated. By doping Ti4+ ions, irradiation resistance of glasses is improved, especially in the case of the higher radiation dose. However, traditionally used stabilizing agent Ce4+ ions exert a negative effect on glasses by increasing the value of irradiation induced absorption coefficient, mu. This is maybe due to the different role of Ce4+ ions in the present Bi2O3-B2O3-SiO2 glass structure.
