UV-visible and infrared absorption spectra of some selected commercial soda - lime - silicate glasses mixed with varied amounts of municipal glass cullet and doped with oxides of tin, manganese, and ceric before and after exposure to a high dose of gamma irradiation [5MR] were studied. XRF analysis showed that the municipal cullet contains high iron concentration and the results revealed that additions of [Mn + Ce + Sn] oxides produce colorless glasses even when containing high municipal cullet contents. It is generally observed that increasing the cullet content resulted in an optical spectrum consisting of three UV bands instead of two UV bands in case of low cullet content. The visible spectra reveal the resolution of two radiation induced bands at about 423 and 540 nm. Gamma irradiation also causes some of the absorption bands to be shifted in their positions. Experimental data are interpreted on the basis of current views on the spectroscopy of glasses
