The effects of radiation on electrical conductivity in ceramic insulators are briefly reviewed with particular emphasis on the radiation-induced electrical degradation RIED effect in which large increases in the intrinsic electrical conductivity have been observed following irradiation within a restricted temperature range whilst subject to electric fields 600Vcm. The aim of the present work was to extend the studies of the RIED effect to temperatures relevant to thermionic fuel elements in space power systems such as TOPAZ II.
