The effect of irradiation with 60Co gamma-quanta in the dose range of 104–106 R on the optical absorption of SiO2 glasses containing BaO or PbO. After such irradiation the glass acquires nice golden or brown colors, absorbs actively the UVradiation, but transmits yellow-orange light, does not have residual radioactivity and gets sterilized. The obtained results allow us to offer the SiO2 glasses containing barium and led oxides for personal protection of eyes from UV-radiation in medicine.
