We propose a physical model of photo-, radio-, and simultaneous photo-radio-darkening of Yb-doped silica optical fibers. This work is complementary to the submission by J-B. Duchez et al., also in this conference, which reports a detailed characterization of the interplay between the pump (photo-darkening) and an external ionizing radiation (radio-darkening). The model predictions are in full agreement with data on photo-darkening and with all of the experiments reported in the Duchez's work.
