High dose neutron and gamma-radiation effects in an epoxy resin

Abstract

The influence of high dose levels up to 1 MGy of both γ- and neutron radiation on the epoxy resin system MY750/HY956 has been studied using d.c. conductivity, thermally stimulated discharge current and differential scanning calorimetry measurements. Inter-related post-irradiation changes in electrical and structural properties have been observed, and these are influenced by annealing processes. A qualitative explanation of the observed effects has been made.
