Resumo: The results of the TL response of the CaSO4:Eu,Ag detectors in the 90Sr/90Y beams of the BSS2 system of the LCI/ IPEN are presented. The TL glow curves were obtained from doses between 30 mGy and 500 mGy. The detectors showed a good reproducibility of the TL response. The calculated calibration factor was (1.166 ?? 0.024) x10-3 mGy/a.u. and the factor determined by linear fitting was (1.120 ?? 0.014) x10-3 mGy/a.u., showing a difference of only 3.9%. The lower limit of detection was (4.96 ?? 0.06) mGy. The detectors indicated the appropriate sensitivity for 90Sr/90Y beta radiation. Preliminary results show suitable dosimetric characteristics for the establishment of a transfer system for beta dosimetry of 90Sr/90Y beams.
