Light-induced TL and light-induced fading of TL in α:Al2O3:C

Experiments were conducted to determine the effect of gamma radiation on the light-induced thermoluminescence (TL) and the light-induced fading of TL in α:Al2O3:C dosemeters. A high temperature peak, at approx. 330oC, was revealed even at the relatively low dose of 0.05 Gy, with greater resistance to light at certain doses. The light-induced fading of TL, the light-induced TL and the phototransferred TL of α:Al2O3:C depend on the dose and the ''history'' of the dosemeters. For low doses, especially when performing environmental measurements, it is recommended to use new dosemeters with a special cover. (author)
