Abstract Irradiation of dielectrics with nonpenetrating electron beams generates long-lasting space charges. A simple experimental and mathematical method is developed for the investigation of charge buildup during irradiation. Time- resolved charge measurements carried out with pulsed beanns of 1-MeV electrons, pulse duration of 4 x 10<sup>-5</sup> sec, and an average current density of 10<sup>-2</sup> A/cm<sup>2</sup> were used to analyze effects of charge leakage caused by radiation- induced conductivity and electron range reduction caused by retardation of the incident electrons in the internal space-charge field. Leakage is found to predominate in silica and borosilicate glass while range reduction predominates in polyethylene.
