Resumo
The dosimetric properties of the SOL-GEL α-Al2O3 detectors with several different concentrations of impurities
were studied in beta radiation beams. 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.
