Radiation electric ocnductivity of polymeric materials

Investigated was the radiation electric conductivity of some polymeric materials (polyethylene terephthalate, polystyrene, polyimeide, fluorolon F-4) under the effect of gamma radiation. Experiments were carried out at room temperature in vacuum on 11-60 μm thick films of two types, differing in the method of silver electrode spraying. It is shown that at radiation dose rate of 100 R/s electric conductivity of films at cathodic electrode spraying is greater than their electric conductivity at the thermal spraying method. A long aging of investigated materials in strong electric fields may change essentially the value of radiation electric conductivity and the character of its dependence on radiation dose rate
