Abstract
Alkali borate glasses interesting application in safe nuclear fuel disposal were investigated under gamma irradiation. Glasses with different composition were prepared by conventional melt quench technique. In order to explore the defects created in the glass structure due to gamma irradiation, the EPR spectrum has been taken before and after high dose rate. The results revealed that the signal of involved paramagnetic species after irradiation shown slow time decay. Annealing procedure was performed to recover radiation damage.File in questo prodotto:
