A frequency variation of about 5 MHz for both Brillouin frequency and linewidth has been measured at the total dose of about 10 MGy. The radiation-induced shift has a negligible practical impact and makes Brillouin scattering very immune to radiation, so that distributed sensors based on this interaction exhibit an interesting potential for use in nuclear facilities. © 2006 IOP Publishing Ltd.Fiber optic sensorsOptical fibersGamma raysBrillouin scatteringSemiconducting germaniumSemiconductor dopingRadiation effectsIonizing radiationtext::journal::journal article::research article
