In this thesis, the development of a novel fibre optic sensor for measuring X-ray radiation in radiotherapy is investigated. The proposed sensor is based on utilising PMMA optical fibres which are coated with an X-ray sensitive scintillating phosphor material which fluoresces when subjected to ionisation X-ray radiation. A literature review of the current methods of radiation detection in radiotherapy applications is presented and a number of shortfalls which were identified are addressed by providing a low cost, real time sensor as a solution for measuring radiation in radiotherapy applications.
