We report the preliminary results from repeated irradiations of optical scintillating fibers exposed to gamma radiation. Optical fibers degrade in radiation fields, but exhibit some recovery once removed. Study of repeated irradiations are difficult to find in the literature. We find that a UV-blue optical wavelength shifting fiber exhibits permanent degradation, the recovery is incomplete, and an interesting two step damage process that appears to affect which wavelengths are darkened at different rates.
