Abstract
The first measurements of radiation effect on the ultrasonic attenuation in tellurite glasses have been carried out in the semiconducting ternary tellurite glasses in the form 50TeO
2 − (50 −
x)V
2O
5 −
xAg
2O where
x = 5, 10, 15, 20, 25 wt.%. The ultrasonic attenuation coefficients have been measured at the frequency 4 MHz and at room temperature. The internal friction inside these glasses has been calculated. Also, the effect of γ-rays doses on the values of the internal friction has been achieved through the doses 0.2, 0.5, 1.0, 2.0, 3.0, 4.0 and 5.0 Gray.
