    Research outputpeer-review


    In situ monitoring of gratings' characteristics during continuous gamma irradiation to a dose of 9 MGy revealed by an order of magnitude weaker Bragg wavelengths drift as compared to gratings written in Ge-doped silica-core fibres. Fibre optic sensing technology brings promising alternatives to classical measurement techniques in harsh nuclear environments.
