Abstract

We report the improved dosimetric properties and kinetic parameters of a newly synthesized strontium/ copper co-doped lithium borate glass composition (LB:Sr,Cu). Co-dopants concentration dependent glow curve shape, Thermoluminescence (TL) sensitivity, TL dose response, minimum detectable dose, fading and reproducibility, annealing, order of kinetics, activation energy, and frequency factors are determined. Proposed dosimeter exhibited simple glow curve, good linearity in the dose range of 0.5-4, 1-10 and 10-100 Gy (Co-60 gamma irradiation), easy annealing attributes, excellent reproducibility, and minimal fading. These attractive features of the prepared glass composition are prospective for radiation dosimetry applications.
