Abstract
The radiophotoluminescence (RPL) and optically stimulated luminescence (OSL) combined signals from Al2O3:C,Mg films were investigated in the dose range of interest in radiotherapy medical dosimetry (0.1–40 Gy). The results showed that the RPL signal is linear over the dose range investigated. The systems based on red excitation have a better dose detection range (starting from 0.2Gy), compared to the system based on UV excitation (1 Gy). The RPL dose measurements are performed using a modular system by illumination of the Al2O3:CMg detectors with 335 nm or 650 nm light and measuring the intensity of the 750 nm fluorescence, while OSL is measured using the modular system with blue 470 nm light. We demonstrated the feasibility of combining RPL and OSL readouts by proposing a protocol where one can acquire cumulative dose response (RPL) and dose reproducibility (OSL). The main challenge was to account for sensitization caused by accumulated dose when using the OSL technique, without affecting the RPL readouts.
