The influence of small doses of gamma -irradiation on the features of the photoluminescence spectra of porous silica glass during long-time (several months) storage after the irradiation is investigated. The non-monotonic dependence of photoluminescence change on the dose of the glasses with a different composition and different additional pre-treatment is observed. The analysis of intensity changes and shifts of the maxims of the photoluminescence spectra shows long-time oscillations. This indicates that the composite catalytic processes take place on the surface of the pores. Perhaps the small gamma -radiation doses initiate the cyclic process of the surface state transformation on the inner side of the pores.
