This paper presents the initial investigation into the effects of magnetic field on the luminescence response of a plastic optical fibre based dosimeter. The optical fibre sensor is based on radioluminescence, whereby a PMMA (polymethyl methacrylate) plastic optical fibre is coated with radiation sensitive inorganic scintillator, Terbium-doped Gadolinium Oxysulphide (Gd2O2S:Tb), that fluoresce when...
A PMMA optical fibre sensor for real-time monitoring of radiotherapy dosimetry is presented. The sensor is based on a X-Ray sensitive scintillating material filled into the micro hole located at one end of the fibre. The scintillating material terbium-doped gadolinium oxysulfide (Gd2O2S: Tb) fluoresces under the X-Ray beam delivered with a range of dose rate from 100MU/min to 600MU/min, and the signal...
