For polymeric materials applied in nuclear environment, the macroscopic properties usually remainunchanged after irradiation for several years or decades up to a threshold dose at which the deteriorationof materials begins to take place. In this paper, the general radiation response of aromatic polymers isfirstly reviewed and discussed. Then percolation theory is employed innovatively to elucidate the criticalphenomenon over the service life for polymeric materials with high radiation resistance. For a betterquantitative evaluation, a novel two-parameter radiation resistance model is proposed by the method ofanalogy between two nuclear-related phenomena. Six epoxy systems are employed from the publishedliteratures to verify the novel model and the result shows that it is reliable and helpful in not onlyestimating the radiation damage over the service period but also multi-objective optimum design ofpolymeric materials.
