Abstract

Radiation resistance was compared between dicyclopentadiene (DCP) resin (P) and epoxy resin (E) by analyzing mainly their complex permittivity ( ϵr' and ϵr«) and electrical conductivity. While both ϵr' and ϵr» increase significantly in E with an increase in total dose of the gamma irradiation, no such increases are observed in P. The conductivity is always smaller in P than in E and the difference becomes larger with the increase in total dose. This difference becomes very obvious if we pay attention to electric modulus spectra. These results indicate clearly that P has a better gamma resistance than E.
