本工作的目的是研究电离辐射影响下的过电压保护。现代电子设备(核、军事和空间技术)在电离辐射条件下的使用带来了电子部件和过电压保护部件的抗辐射问题。这些部件在电离辐射影响下的可靠性问题也是一个相关问题。导致材料特性发生不可逆变化的整个辐射效应被定义为剂量效应或积分效应。为了确定辐射效应，测试了材料过电压(过电压二极管、压敏电阻、充气浪涌避雷器和电容器)在n/SUB+//SPL伽马/槽源辐射影响下的电阻。已确定过压二极管对辐射高度敏感。辐射对压敏电阻的影响与对过压二极管的影响相似。充气避雷器的特性出现了暂时的改善。确定了在辐射的影响下，电容器的容量减小。对所得结果进行了理论解释。
The aim of this work is the examination of the over-voltage protection under the influence of ionizing radiation. The use of modern electronic devices (nuclear, military and space technology) in the conditions of ionizing radiation brings up the question of radioactive resistance of electronic components and over-voltage protection components. The question of reliability of these components under the influence of ionizing radiation is also a relevant one. The entire effects of radiation, which cause the irreversible changes of the material characteristics, are defined as the dosage or integral effects. The resistance of the material over-voltage (the over-voltage diodes, varistors, gas filled surge arresters and capacitors) subjected to influence of n/sub +/ /spl gamma/ radiation from californium source was examined in order to determine the radiation effects. It was determined that over-voltage diodes are highly sensitive to the radiation. The effects of radiation on varistors are similar to the effects on the over-voltage diodes. Gas filled surge arresters showed the temporary improvement of characteristics. It was determined that under the influence of radiation the capacitor capacity decreases. The results attained are explained theoretically.
