Thermoluminescence glow curves above room temperature and the related optical absorption spectra have been studied on MgO single crystals irradiated by electrons, X-rays or UV-light, with emphasis on conditions which are of interest for applications to radiation dosimetry. The relatively pure MgO speciments shown high response, in which the intensity of thermoluminescence is linear for a wide range of radiation doses. The glow peak temperatures depend somewhat on impurities in the samples, but not on the kind of radiations. The first peak appearing at about 87℃ is intimately related to the V^- centers. In intensity decreases in proportion to the optical bleaching of the V^- band even under the room light. The third and fourth peak appearing at about 144 and 180℃ are thought to be most suitable for dosimetry use.
