Sensors, Vol. 21, Pages 5157: Dosimetric Application of Phosphorus Doped Fibre for X-ray and Proton Therapy Sensors doi: 10.3390/s21155157 Authors: Olugbenga J. Olusoji Crystal Penner Camille Bélanger-Champagne Wern Kam Michael Martyn Peter Woulfe Cornelia Hoehr Sinead O’Keeffe Phosphorous-doped silica optical fibres with a core diameter of 4 µm were tested in X-ray and proton fields for application in cancer therapy dosimetry. Specifically, the radiation-induced attenuation was investigated in terms of linearity in deposited dose in 15 MV and 6 MV photons and 74 MeV protons, as well as Bragg-peak detection along the proton track. Fibres were found to demonstrate linear relative dose response in both radiation modalities, but possible saturation did occur at the high linear energy transfer of the Bragg peak. This demonstrates the possibility to use these fibres as a relative dosimeter for radiation therapy applications.
