In this work, the thermoluminescence (TL) dosimetric characteristics of lithium borate glasses have been studied in detail before and after doping with silver. The glass specimens were prepared using a conventional melt-quenching method and checked using X-ray diffraction (XRD) pattern. The resultant glow curve of the undoped γ-irradiated samples showed one strong peak at about 178 °C and at a constant heating-rate (β) of 5 °C/s. While, the Ag-doped samples showed two TL glow peaks around 220 and 320 °C, which were mainly attributed to the Ag+ ions. Trap parameters of glow peaks of the present glass systems were extracted. The dosimetric characteristics of glass specimens were read from the TL γ-dose response curve, which showed a reasonably good linearity behavior between glow peak areas and γ-dose values. The present results revealed the importance of using such current selective glass structures as γ-radiation detectors within the studied dose-range where an acceptably good fading response was observed.
