For the characterization of the detectors, the TL and OSL techniques were used. A TL spectrum was acquired. The detectors showed adequate OSL and TL dosimetric characteristics, such as good reproducibility, a glow curve with the peak at ~230 °C at 5 °C/s of heating rate, adequate OSL decay curve, good linearity of response and high phosphor sensitivity. A thermal treatment study was also performed. Moreover, the calibration factors and the lower detection limits were determined for beta radiation. These characteristics indicate the suitability of SOL-GEL α-Al2O3 detectors for the establishment of a transfer system or alternative/complementary method for beta radiation dosimetry.1-7openAccesssol-gel processradiation detectorsaluminium oxidesdosemetersradiationsbeta particlesbeta sourcesthermoluminescenceluminescencestimulated emissionArtigo de periódico16710.1016/j.radphyschem.2019.02.0190000-0002-7362-2455https://orcid.org/0000-0002-7362-245566.4372.00
