The glass samples were produced by fusion and fast cooling method. The dosimetric characterization was performed via thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques. For this characterization, the samples were irradiated with a beta source (90Sr/90Y). TL emission curves, kinetic parameters, OSL decay curves, dose response curves, and the correlation between TL and OSL results were obtained. X-ray diffractometry (XRD) and infrared spectroscopy (FT-IR) of the samples were also performed. The XRD analyses confirmed the amorphous nature of the investigated glasses and the FT-IR analyses showed the different borate groups in their compositions. The TL emission curves of the glasses are composed by three peaks, located at different temperatures. The dose response curve in both TL and OSL analyses indicated linearity for most of the dose range studied. The OSL decay curves exhibited two components with different decay times.150-157openAccessleadboratesglassthermoluminescenceluminescencealuminiumdosimetryradioluminescenceArtigo de periódico155SI10.1016/j.radphyschem.2018.02.005https://orcid.org/0000-0002-7362-245560.15373.00
