摘要：

The ultrasonic velocity for different compositions of irradiated recycled heavy metal oxide (HMO) borosilicate glasses of the xBi(2)O(3)-50BaO-(50 - x)borosilicate glass system (where x = 0, 5, 10, 15, 20 mol.%) has been studied by using the pulse echo technique. The elastic moduli, Debye temperature, Poisson's ratio and microhardness have been obtained from the experimental data. Changes in the structure after irradiation have been investigated by using FUR spectroscopy and ultrasonic studies. As the changes are strongly dependent on the internal structure of the absorbing materials, the ultrasonic velocities in borosilicate-barium-bismuth glasses are measured before and after gamma-irradiation as a function of composition, from which the structural changes in the B-O and Si-O-B bond due to irradiation are obtained.
