Influence of gamma-irradiation upon properties of glasses have scarcely been studies excepting phenomena such as coloration and fluorescence caused by the irradiation. In this study, therefore, not only the influence of gamma-irradiation upon the electric conductivity of glasses, but applicability of glasses exposed by gamma-rays to semi-conductive glass or radiationdosimeter was studied. The electric conductivity for ten kinds of glasses were measured after irradiating gamma-rays up to the maximum dosage of 10^7r. Using Co^<60> For the measurement of the electric conductivity, a vacuum tube voltmeter was used for the range of low resistance values and a vibration reed electrometer for the range of high resistance. The result of the measurement showed that no change in electric conductivity of the glasses occurred by the irradiation of 10^<7r>. And consequently the gamma-irradiation to the glasses was found to be unapplicable in making semi-conductive glass and glass-dosimeter.
