    We report on the radiation assessment of hydrogenated aluminium coated 200 µm pure silica core fibres. It is experimentally demonstrated that hydrogen protected the fibres against the radiation-induced absorption. With such appropriate hydrogen treatment the fibres can survive the ITER radiation environment in the vicinity of the labyrinth region of the tokamak reactor.
