A number of investigators have shown that glass on exposure to radioactive and X-radiation becomes coloured. Sheline, Sharp and Arner suggested that this may be due to F-centres similar to those produced in alkali halides when bombarded by X-rays and cathode rays. Yokota found that F-centres could be created in fused silica and α-quartz by X-irradiation. He further showed that alkali silicate and borate glasses become coloured on X-irradiation due to formation of F-centres. Przibram showed that F-centres could also be created in borate glass by β- and bold γ-irradiation from radium.
