Glass structure responses to gamma irradiation using infrared absorption spectroscopy and ultrasonic techniques: a comparative study between Co2O3 and Fe2O3.

The response of glass to radiation was investigated using ultrasonic and FTIR spectroscopy. New materials were prepared from borosilicate-based glass with different cobalt and iron oxide compositions. The results indicate that the glass structures were most responsive to irradiation at 1500 Gy. Moreover, the results show that the radiation effect decreases when the cobalt and iron oxide compositions increase. These results are relevant to studies on high-dose processing, radio-pharmacy and storage.
