Abstract:
The potential and limitations of silica optical fibers used for radiation induced attenuation (RIA) - based radiation monitoring applications are evaluated. Under irradiation the macroscopic properties of the optical fibers are modified. The radiation induced attenuation phenomenon contributes differently to the degradation of the optical fiber performances depending on the fiber profile of use. Their radiation sensitivity has been observed with variation of dose rates, monitored wavelength and their recovery nature. The morphological changes of the optical fiber structure have been performed by Scanning Electron Microscopy and the Atomic Force Microscopy analysis.
