Superfluorescent fiber source (SFS) is generally considered to be promising in optical sensing. In this paper, the gamma radiation effect on the double pass backward (DPB) SFS was investigated. Firstly, a sample of DPB SFS together with a 9 m Er-doped fiber (EDF) was irradiated by 60Co source with radiation dose rate of 3.6 Gy/h and total dose of 200 Gy. And the results were analyzed to find that at the very start of radiation the RIL of the sampled Er-doped fiber was greater than that of sampled SFS while at about 100 Gy the RIL slope of the EDF became less than that of the SFS. Above all, the loss from EDF was dominant to that from the SFS in gamma radiation environment. Mean wavelength of the SFS drifted about 4 nm mainly caused by the radiation loss. In the end, the potential influence to FOGs in space applications was simulated.
