Abstract

The use of a PMMA based plastic optical fibre in radiotherapy dosimetry is presented. The optical fibre tip is coated with a scintillation material that fluoresces under ionising radiation, with the emitted signal penetrating the fibre and propagating along the fibre for remote monitoring through a spectrometer. A clear, quantifiable signal is emitted at 546nm on exposure to 6MV radiation from a Siemens Linear Accelerator.
