This study aims to investigate the characteristics of optical fiber sensors under X-rays radiation. The Radiation-Induced Absorption (RIA) and Radiation-Induced Refractive-Index Change (RIRIC) in the UV-VIS domain were investigated. Single and multi-mode optical fibers (SMFs & MMFs) have been used for this purpose. The outer diameters of these fibers were reduced from (125 to 50 and 55μm for SMF and MMF respectively) via chemical etching process then dipped into (3 wt % concentration) of germanium (Ge) solution to produce the sensing part of the fibers. Due to the applied X-rays radiation, an attenuation of the spectrum and a redshift in peak wavelength were achieved. Both sensors show good responsivity to the applied radiation and the MMFs sensors showed higher wavelength shifting as compared to SMFs sensors.
