In this paper we report on the measurement of the refractive index profile of optical fibers exposed to the gamma radiation. The tool we used for determining the refractive index distribution is microinterferometric tomography. Nuclear radiation is known to affect the guiding properties of optical fibers and it is therefore essential to characterize these effects to assess the applicability of fiber-optic technology for communication and sensing in space applications and in nuclear industry. We show that the fibres exhibit a slight refractive index increase which confirms results reported earlier.
