Аннотация:The dependences of radiation-induced losses from doses of absorbed γ-radiation on a standard optical fiber SMF with a core (SiO 2 - GeO 2 ) are investigated. The influence of laser radiation power to the time of optic fiber transparence recovery (relaxation of coloring centers) is established. The method of γ-radiation influence compensation on the optic fiber during its long-term exploitation in the zone of radioactive exposure is proposed.
