This work examined the influence of resin and hardener structure, together with the associated processing variables, on the rate of radiation induced gas evolution. Glycidyl ether and glycidyl amine resins are considered, together with aromatic amine and acid anhydride hardeners and such processing variables as cure schedule, accelerator content and amount of anhydride hardener. The effect of specimen geometry on the total gas evolved for unit radiation dose is also examined.

A range of ‘radical scavengers’ has been investigated, in relation to the structure of the resin and hardener components, to investigate the possibility of reducing the total radiolytic gas evolution. A nuclear reactor was used for the irradiation studies — and a system of dosimetry based on the well characterised gas evolution from polyethylene provided comprehensive information relating to dose distribution within the reactor
