Abstract
The effects of pile irradiation on various modifications of silica have been extensively studied in the past. Structural investigations are reported here of the effects of such irradiation on the cristobalite form of silica and on a variety of materials related to silica structurally or chemically. These are GeO2, BeF2, SnO2, TiO2, AlPO4, GaPO4, AlAsO4 and sodium silicates. Only silica undergoes gross disordering on irradiation but the susceptibility to radiation damage is not simply associated with glass forming ability. Qualitative conclusions are presented which relate the resistance to radiation damage with bond character and chemical constitution.
