Optical Fibre Luminescence Sensor for Real-time Radiotherapy Dosimetry

Not Accessible

Your library or personal account may give you access


A plastic optical fibre, coated with a terbium-doped gadolinium oxysulfide phosphor (Gd2O2S:Tb) is presented. The paper presents the sensor’s response to a range of known radiotherapy exposure patterns and characterises its response to varying energy levels and dose rates.
