Abstract

The primary process in the interaction of radiation with matter is the production of ions and electronically excited states of molecules, which in turn may lead to the formation of free radicals. The subsequent changes occurring in the material will be manifested in both transient and permanent effects that can be measured by suitable test procedures. The establishment of criteria for the evaluation of the radiation endurance of insulating materials is very complex, since such criteria will depend on the total environment and the application in which the materials are used.
