In this work, we investigated the feasibility of using phosphorus (P)-doped optical fibers to monitor the dose levels during various types of irradiations like protons, neutrons, X-ray or rays. This class of fibers was shown to be a good candidate for dosimetry mainly in the near-IR and the IR and for extremely low dose ranges. In this study, we choose to evaluate the spectral and time dependence of the radiation-induced attenuation (RIA) of these fibers in the ultraviolet (UV) and visible range of wavelengths. In this spectral domain, the RIA levels are considerably higher than in the IR and time-resolved distributed dosimetry with better spatial resolution may be achieved if the fibers present the requested response (linear with dose, dose-rate independent).
