Abstract

A new single-aliquot regenerative-dose (SAR) protocol for measuring the equivalent dose using the thermally-transferred OSL (TT-OSL) signal is proposed. Characterisation of the Basic Transferred OSL (BT-OSL) signal measured using a previous protocol showed that it was unnecessary to measure the BT-OSL thus allowing simplification of the SAR protocol for TT-OSL. To remove the BT-OSL, holding the aliquot for 100 s at 300 °C without optical stimulation at the end of each SAR cycle gave the most reproducible results. A simplified protocol incorporating this heat treatment was tested by recovering doses up to 700 Gy which had been given to a modern sand sample with an equivalent dose of less than 5 Gy.
