Dosimetric characteristics of high sensitive Mg2SiO4:Tb solid TL detector

Thermoluminescence dosimetric characteristics of Mg2SiO4:Tb in form of sintered pellets developed at the Institute of Nuclear Sciences, Vinca, Belgrade, are presented. Mg2SiO4:Tb is a TL material with attractive features for dosimetric applications such as ultra high TL sensitivity, simple glow curve with the main TL peak at about 210 degrees C and low fading. The dosimetric properties of this TL detector examined in this study include glow curve shape, TL sensitivity, annealing procedure and reproducibility, photon dose response, minimum detectable dose, energy response, fading characteristics, light induced effect and optically stimulated luminescence (OSC) signal.
