An attempt to determine the saturation dose for PRESAGEtm

Abstract

This brief work-in-progress outlines two methods that we have attempted for determining the dose at which the linear relation between optical density of a PRESAGE3 dosimeter and the dose deposited breaks down. Both methods were equally successful in mapping the linear relation up to an optical density of approximately 6.25 cm-1 (absorbance 2..5), but no saturation was found in this region. © 2009 IOP Publishing Ltd.
