Resumo
The OSL characteristics of three different borate glass matrices containing magnesia (LMB), quicklime (LCB) or
potassium carbonate (LKB) were examined. Five different formulations for each composition were produced
using a melt-quenching method and analyzed in terms of both dose-response curves and OSL shape decay. The
samples were irradiated using a 90Sr/90Y beta source with doses up to 30 Gy. Dose-response curves were plotted
using the initial OSL intensity as the chosen parameter. The OSL analysis showed that LKB glasses are the most
sensitive to beta irradiation. For the most sensitive LKB composition, the irradiation process was also done
using a 60Co gamma source in a dose range from 200 to 800 Gy. In all cases, no saturation was observed. A
fitting process using a three-term exponential function was performed for the most sensitive formulations of
each composition, which suggested a similar behavior in the OSL decay.
