We report preliminary results from in situ monitoring of an optical scintillating fiber while being exposed to a cesium-173 gamma radiatior. We measured the degradation of fiber transmittance across the visible spectrum as a function of time. We observed that the region below 500 nm was degraded quickly and thoroughly while wavelengths above 500 nm lost clarity more slowly.
