Abstract

This tutorial reviews the presently understood mechanisms that are responsible for the radiation effects in glasses, namely absorption, luminescence and compaction. The paper introduces the reader to the general concepts found in amorphous material to understand the radiation damage and both the defect creation-annealing mechanisms in silica glass. In particular, we address the practical case of optical fibres under gamma and neutron radiation. The fibre optic fabrication technology is reviewed with its implication in term of radiation tolerance. We also present practical methods used to alleviate the impact of radiation on the optical transmission fibre, like hydrogen loading and fluorine core-doped fibre. Finally, few practical examples illustrate the applicability of the fibre optic technology in radiation environment.
