Optical absorption and photoluminescence spectra of lead silicate glass irradiated by 5- to 10-MeV electrons are studied. High-energy electron irradiation is shown to result in the formation of colour centres generally similar to those being formed by X-ray and g-radiation. The most probable factors responsible for the non-sensitivity of the photoluminescence of the investigated lead silicate glass to the electron irradiation are discussed.
