Applicability of OSL pre-dose phenomenon of quartz in the estimation of equivalent dose

The feasibility of utilizing the pre-dosed OSL signal in the estimation of the equivalent dose has been investigated. The results based on (i) the behavior of growth curve, (ii) dose recovery tests and (iii) non-bleachability of reservoir centres, R-centres, suggests that (i) the pre-dosed OSL does not seem to work satisfactorily in dose estimation unlike the pre-dosed 110 °C TL emission and (ii) it may not be applicable in case of bleached specimen.
