Radioluminescence (RL, i.e. prompt luminescence emitted during exposure to ionizing radiation) is used for analysing luminescence emission processes and has been proposed as a method for determining received radiation doses in both natural and synthetic radiation dosimeters. We describe here an automated system capable of both multi-sample RL analysis and comparative studies using traditional thermoluminescence (TL) and optically stimulated luminescence (OSL) methods. The radioluminescence unit is intended as an attachment for the existing automated Risø TL-OSL systems; it delivers a dose rate of 4.5 Gy/min to materials such as quartz, using an 80 mCi90Sr/90Y β-source. The unit enables the measurement of RL in the temperature range 25-500°C using both continuous and pulsed radiation exposures. Measurements are fully automated, allowing up to 48 samples to be measured in any one experimental run. Results from several experiments are presented for two representative do simeters; natural quartz and artificial Al2O3:C. These experiments include investigation of the dose and temperature dependence of RL, pulsed RL, and spectrally resolved RL; comparisons with TL are also made.
