Abstract: The dose-rate effect on the spectral characteristics of the fiber Bragg grating written in the germano-silicate optical fiber incorporated with boron oxide in the inner cladding under gamma-ray radiation was investigated for sensing applications. The Bragg peak shift of the FBG was found to saturate at a 78 pm level and a radiation-induced attenuation of 1.345 dB/m was obtained with the accumulated dose-rate of 22.86 kGy/h. However, the full-width half maximum bandwidth of the FBG remained practically unchanged.
