<jats:title>Abstract</jats:title><jats:p>Transient radiation‐induced conductivity of polystyrene resulting from single pulses (0.3 ms) of 65 keV electrons in vacuum has been investigated. The activation energy of the delayed component was found to be 0.17 eV. Doping of polystyrene with additives (rhodamine‐6G, tetracyanoethylene) is consistent with the fact that this polymer is hole conducting. Transit time effects in polymer films of 20 μm thickness are practically absent at fields less then 10<jats:sup>8</jats:sup> V/m. The application of the proposed theory of the transient hopping conduction and its relationship to the conventional band model of photo‐ and radiation‐induced conductivity in amorphous semiconductors is also discussed.</jats:p>
