    Abstract

    Radiation resistance was compared between dicyclopentadiene resin (P) and epoxy resin (E) mainly by analyzing their dielectric propertiespropertiespropertiespropertiespropertiespropertiesproperties. When the resins are irradiated by γ-rays, their band gap energies decrease. This decrease is more significant in E than in P. Although electrical conductivity and both the real and imaginary parts of complex permittivity are increased very dramatically in E, no such increases are observed in P. These results indicate that P has superior radiation resistance to E.
