Simplified Nuclear Glasses Structure Behaviour Under Various Irradiation Conditions: A Raman Spectroscopy Study

The effects of the 244Cm alpha decays, 1-3.5-7 MeV multi-energy gold ions irradiations and 74 MeV krypton ions irradiation) on the structure of a six oxide glass (SiO2-B2O3-Na2O-CaO-Al2O3-ZrO2) are compared using Raman spectroscopy. The results suggest that the effects on the glass properties induced by these three kind of irradiations are similar, revealing a depolymerisation of the silicate network and a decrease of the boron coordination number.
