Resumen
In this work the feasibility of using Mg2SiO4:Tb as a fiberoptic radioluminescent (RL) dosimetry probe for real-time dosimetry has been investigated for the first time. In particular, the stability of the RL signal after repeated use, the spectrum of the RL emission and the dose-rate response curve of a Mg2SiO4:Tb-based fiberoptic probe have been determined. The probe has been also used to obtain a percentage dose depth curve in a water phantom and its performance has been compared to that of a standard ion chamber. Besides, its absolute RL yield has been compared to that of an RL probe based on the commercial Al2O3:C phosphor.
