Online X-ray RIA (radiation induced attenuation) has been measured for differently doped aluminosilicate optical fibers. The acquired data in the visible spectral range show the generation of absorption bands and that their generation is dose rate independent. The optical data will be completed by additional Electron Paramagnetic Resonance measurements to highlight the presence of defects attributed to Al and support the attribution of Vis-IR RIA bands to Al centers.
