A SAR protocol for heat-sensitive materials exhibiting sensitization (SARHS) for the estimation of the equivalent dose

In the present work, a novel single aliquot regenerative-dose protocol suitable for heat-sensitive materials exhibiting sensitization (called SARHS) for the estimation of the equivalent dose with OSL is proposed. The protocol eliminates any sensitization effects without encompassing any heating of the sample. Validation of the SARHS protocol was accomplished with three different heat-sensitive materials which exhibit sensitivity changes with the repeated use of the same sample (sensitization), i.e., dragonfly wings, a commercial solid drug (Daktarin) and chicken bones, in which the natural equivalent dose could be successfully recovered with negligible error even when fading, after exposure to irradiation, of the natural OSL signal was taken into account.
