Title Neutron and Gamma Irradiation Damage to Organic Materials.
Publication Date Apr 2012
Media Count 33p
Personal Author G. Von White R. Bernstein
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.
