Abstract
Thermoluminescence (TL) measurements were performed in crystal samples of α‐Al2O3 (TLD 500 K) subjected to UV irradiation in the range of 200–320 nm. The material is very sensitive to UV light and can be considered potentially useful for actinic region dosimetry. The TL glow curve is composed of two glow peaks centered at 58 and 184 °C, respectively. The TL excitation spectrum shows a maximum for 220 nm light.Keywords
