摘要：

Possible change in electrical conductivity and dielectric loss factor in ceramics under ionizing irradiation has been evaluated. First, evidence for formation of transient lattice defects by ionizing irradiation is presented and their yield is evaluated. Then the contributions of the transient defects as well as electron-hole pairs to the electrical conductivity and dielectric loss factor are compared and it is pointed out that the electron-hole pairs make a major contribution to the electrical conductivity, while the contribution to the high-frequency dielectric loss factor is dominated by the transient defects. A model calculation of the conductivity and dielectric loss factor under irradiation for Al2O3 is presented.
