Fading estimation of SOL-GEL α-Al2O3 detectors

The OSL and the TL techniques are used in several fields of radiation dosimetry. The dosimeters are affected by a signal loss in the time between the irradiation and readout (fading). This undesirable characteristic can cause an underestimation of the irradiation dose. The fading estimation of SOL-GEL α-Al₂O₃ with several different concentrations of impurities is reported. The thermal fading and the light-induced fading of the SOL-GEL α-Al₂O₃ detectors were estimated. Furthermore, the exponential equations used to interpolate the experimental results were presented.
