Abstract
We propose, and verify in the case of a Ge-doped-silica-core optical fiber, a general explanation for the power-law dependencies on dose frequently observed for the radiation-induced attenuation in optical fibers. This insight permits detailed prediction of the post-irradiation recovery curves, given just the empirical exponent of the power law, 0 < f < 1, and the experimental irradiation time, t{sub irrad}. The time constant of the recovery is given by t{sub irrad}/(1-f), in both first, and second-order kinetics. We establish a microscopic model of radiolytic oxygen molecules for the {gamma}-ray-induced absorption at 1.3 {mu}m in our test fibers and infer a diffusion limited bimolecular recombination process. (author). 19 refs., 6 figs.
