Abstract

Lead glasses which are used widely in hot cell construction in the same chemical compound, have been irradiated in the tangential beam tube on TRIGA Mark-Il Reactor settled in Istanbul Technical University. Using neutrons in the tube has done the irradiation process. The bismuth filter had been placed at the end of tube against the gamma ray. Other glass samples have been also irradiated by Co-60 gamma source which has 9.18 Ci activity, for the comparison. The glass colours turned to brownish orange from clear hue via the dose rates. After the high level irradiation, properties of visible light transmittance are determined between 380 nm and 780 nm wavelengths for all glass samples. Changing rate of colours is determined on the colour maps. Colour coordinates, purity, brightness and dominant wavelengths are determined which evaluated comparative with the unexposed glasses.
