Abstract

The authors present the results of investigations concerning thermally stimulated depolarization currents and measurements of permittivity, loss factor and DC conductivity from X-ray and γ-ray irradiated commercial 125 μ Estrofol polyethylene terephthalate films. Samples were irradiated with three different doses in different gaseous environments (air and N₂) and the electrical properties were measured as a function of time. A distribution of activation energies of relaxation processes responsible for the α and ρ peaks was found by applying partial heating techniques
