利用日本材料试验堆(JMTR)的裂变反应堆，研究了钙-锆铟氧化物陶瓷(CaZr0.9In0.1O3d)的辐照电学性能变化。由于电子激发引起的辐射感生电导率(RIC)、辐射感生电动势(RIEMIF)和辐射感生电性退化(RIED)增加了CaZr0.9In0.1O3d在反应堆辐照下的电导率。在反应堆功率不变的情况下，随着辐照时间的延长，RIC和RIEMF逐渐减小。此外，辐照后检测(PIE)实验证实，辐照使材料的初始电性能和热性能完全退化。这些辐射效应归因于中子碰撞引起的原子位移所产生的点缺陷或其团簇，也可归因于辐射分解。
Radiation induced changes in electrical properties of calcium-zirconium-indium oxide ceramics (CaZr0.9In0.1O3-d) were investigated using a fission reactor of Japan Materials Testing Reactor (JMTR). Electrical conductivity of CaZr0.9In0.1O3-d under the reactor irradiation increased by the Radiation Induced Conductivity (RIC), Radiation Induced Electromotive Force (RIEMIF)and Radiation Induced Electrical Degradation (RIED), caused by the electronic excitation. The RIC and the RIEMF decreased gradually for the constant value of the reactor power with the increase of irradiation time. Moreover, it was confirmed by Post-irradiation Examination (PIE) experiments that the initial electrical and thermal properties were completely degraded by the irradiation. These radiation effects are attributed to point defects or their clusters produced by atomic displacements caused by neutron collisions and also by the radiolysis.
