Abstract
Measurements of conductivity, permittivity, and dissipation factor on polystyrene, low‐density polyethylene, poly(ethylene terephthalate), and polytetrafluoroethylene under irradiation with x‐rays at exposure rates from 0.004 to 400 r/sec. are presented. The radiation‐induced anomalous conductivity as well as the induced dielectric loss are interpreted by Maxwell‐Wagner polarization due to radiation imbalance in surface layers of the specimen. The nature of radiation‐induced steady‐state conductivity is also discussed.Keywords
