Fiber Bragg grating (FBGs) are expected as sensor for monitoring of a large scale faculty because of their availability to measure multiparameter at many point along a fiber. In this study, we investgated the influence of radiation on the characteristic of FBGs that must be understand before applying FBGs to nuclear plant. FBGs written on fiber made from one perform with same condition were exposed to fast neutrons up to 1.7x1017n/cm2 or ?-rays up to 710KGy and their Bragg peak shift of 0.072nm anmd 0.027nm in the peak wavelength are observed in the maximum respective.
