This paper presents an experimental study of the most characteristic defects in synthetic alpha-quartz by using thermoluminescence (TL) and EPR techniques. The light sum corresponding to any given TL peak is proportional to the trap concentration. The dependences of the light sum on the total gamma dose is presented in a log-log plot. The defects of the first type produce electron traps after gamma irradiation of alpha-quartz at a depth of (0.9 +/- 0.1) eV. Upon a single heat treatment of alpha-quartz followed by gamma-irradiation the vacancy-type defects become dominant, formed by the transformation of structural defects containing silanol groups.
