Abstract

Thermoluminescent dosimetric characteristics of MgB4O7:Dy,Na are presented. MgB4O7:Dy,Na is a newly prepared TL material with attractive features for dosimetric applications, such as near-tissue equivalence, simple glow curve, high sensitivity and low fading. The dosimetric properties of this material examined in this study include glow curve shape, TL sensitivity, annealing procedure, photon dose response, minimum detectable dose, precision of TL measurements, reproducibility, energy response and fading characteristics.
