Abstract

An optical fibre sensor for monitoring low dose radiation is presented. The sensor is based on a scintillation material coated optical fibre, which emits visible light when exposed to low level ionising radiation. The incident level of ionising radiation can be determined by analysing the observed emission spectra. The work presented reports on the design of the sensor and the stability of the sensor during measurement of incident x-ray energy. Initial testing of the sensor at the radiotherapy facility at the Galway Private Clinic is presented, demonstrating the suitability of such a sensor for a range of radiotherapy dosimetry applications.
