Abstract
For the first time the feasibility of using beryllium oxide (BeO) ceramics as a fibre-coupled radioluminescent dosimeter is investigated. BeO ceramic exhibits both radioluminescence (RL) and optically stimulated luminescence (OSL), and has the potential to be a near tissue equivalent alternative to Al2O3:C. A BeO fibre-coupled radioluminescence dosimeter is demonstrated and characterised for 6Â MV X-rays and superficial X-ray energies, 150Â kVp and 120Â kVp. Based on the results, we demonstrate the capability of the RL BeO FOD for accurate and reproducible dose measurements with a linear dose rate and dose response. It has also been found that the percentage depth dose curves for 6Â MV agreed with ion chamber measurements to within 2%, except in the build up region. For the 150Â kVp and 120Â kVp photon beams, the depth dose measurements agreed with ion chamber measurements to within 2.5% and 4%, respectively.
