Resumo
Calcium sulfate doped with dysprosium (CaSO4:Dy) has been used for personal dosimetry
using the thermoluminescence (TL) technique for decades and its TL properties are well-known.
Considering the advantages of the OSL technique (relatively simple and faster readout and detector
reusability) and the potential application of CaSO4:Dy as an OSL detector, this study aimed to
investigate the dosimetric properties of CaSO4:Dy using the OSL technique. The present study
was carried out using CaSO4:Dy pellets prepared at IPEN irradiated and read in a TL/OSL Risø
reader with blue light stimulation and Hoya U-340 filter. OSL dosimetric properties essentially
dose response, reproducibility, and fading characteristics were evaluated. Moreover, TL and OSL
signals were compared to study the correlation between OSL signals and TL peaks. CaSO4:Dy OSL
response is linear from 0.1 to 10 Gy and shows reproducibility better than 5%. The low-temperature
TL peak is unstable; however, the OSL signal seems to be associated with higher-temperature peaks.
