Title Neutron and Gamma Irradiation Damage to Organic Materials.

Abstract This document discusses open literature reports which investigate the damage effects of neutron and gamma irradiation on polymers and/or epoxies--damage refers to reduced physical chemical, and electrical properties. Based on the literature, correlations are made for an SNL developed epoxy (Epon 828-1031/DDS) with an expected total fast-neutron fluence of approx. 10(sup 12) n/cm2 and a a dosage of approx. 500 Gy received over approx. 30 years at < 200 DGC. In short, there are no gamma and neutron irradiation concerns for Epon 828-1031/DDS. To enhance the fidelity of our hypotheses, in regards to radiation damage, we propose future work consisting of simultaneous thermal/irradiation (neutron and gamma) experiments that will help elucidate any damage concerns at these specified environmental conditions.
