The effects of ionizing radiation on dielectric conductivity of common electronics materials will be studied. Following development of an acceptable protocol, conductivity for a number of materials will be studied as a function of energy of the ionizing radiation, intensity, temperature and temporal dependence of phenomenon. These data will be used to amend the protocol to permit study in subsequent work of the phenomenon on the full extent of common electronics materials. A preliminary empirical model, based on both theoretical studies and on data gathered as a part of the proposal will be developed which should permit designers to accommodate this phenomenon.
