Radioactive resistance of solid dielectrics

Effects of interaction of radioactive radiation with dielectric materials which have been used for passive isolators construction can be neglected, compared to the influence of other factors (humidity, temperature, aging, chemical reactions). On the other hand, consequences of radioactive radiation on dielectric components of active electric circuits may result in significant changes of their functions. Basic components of active electric circuits whose functioning is based on dielectric materials are capacitors. Having in mind the constructive solution of discrete capacitors which are used in electronics it is reasonable to expect the influence of neutron and gamma radiation only. The aim of this paper is to examine the influence of neutron and gamma radiation obtained from /sup 252/Cf and /sup 60/Co on the dielectric loss factor and capacitance of the polycarbon and liscun capacitors. The obtained results are explained theoretically.
