[show abstract][hide abstract] ABSTRACT: We have investigated the effects of ionizing radiation-induced changes on dispersion and refractive index in photonic crystal fibre, boron co-doped photosensitive fibre and standard SMF-28 fibre up to a level of 7 MGy of 60Co γ-radiation. We have been unable to observe any changes within an experimental error of ~1% for the dispersion value and <1.5 × 10−3 for the refractive index.
