Abstract
Oxygen vacancies are created in quartz by artificial gamma-ray irradia tion at two stages with very low efficiencies. G values (G: number of vacancies created per 100eV) were found to be 4.7x10(-4) and 2.6x10(-5 ) at heat-treated E(1)(') intensities. The intensities are consistent with those observed in natural quartz in granites, when external doses given by beta and gamma rays to quartz in granites are taken into acc ount with the above efficiencies.
