Radiation protection of fiber optic materials: Effects of oxidation and reduction

Abstract
The response to ionizing radiation of a suite of high‐purity silicas, a titanium‐doped silica, high‐purity germania, and silica fibers with germanium‐doped and titanium‐doped cores has been measured. The radiation sensitivity of these materials was found to depend upon the atmosphere used during a heat treatment prior to irradiation.
