ABSTRACT

The evolution of novel procedures for the evaluation of equivalent dose using the optically stimulated luminescence (OSL) signal of quartz became necessary to address (i) the sensitization experienced by the signal during the pre-heat treatment and (ii) the in situ sensitization occurring in nature. The pre-dose phenomena of the OSL and 110 ◦C TL pre-dose emissions have been reported to be similar. In light of this observation, an attempt has been made in this paper to visualize the role of R-centres in the sensitization process of the OSL emission. The results, based on the experimental observations and kinetics considerations of R-centres, confirm that the R-centres participate in the sensitization process of this signal.
