Thermoluminescence (TL) properties of Al2O3: C, Mg exposed to cobalt-60 gamma radiation doses

TL characteristics of powder form of Al2O3doped with 0.1 mol% carbon and co-doped with different magnesium concentrations of 0.1 mol% and 0.2 mol% exposed to Cobalt-60 gamma ray at doses ranging from 5 Gy to 70 Gy were investigated. The recorded glow curves consist a dominant peak at 180 °C for a he...
