Popis:	Gamma-ray and 1.5-MeV electron irradiations are employed in the temperature range 25–175°C to produce radiation effects in undoped paratellurite (α-TeO2) single crystals. Optical absorption and ESR techniques are used to study the growth and annealing of point defects, and spectroscopic observations by these two methods are compared. Pulseannealing experiments are reported over the range 100–500°C. The TeO2 crystal shows much more susceptibility to radiation damage at the higher irradiation temperatures.
