Abstract

To determine the equivalent dose (ED) using conventional methods any part (or all) of the optically stimulated luminescence (OSL) decay curve can be chosen as representative luminescence signal. Recently several studies investigated the shape of OSL decay curves and showed that the luminescence emission can be decomposed into fast, medium and slow components. From this point, in this work, the ED values determined using multiple aliquots process (MAAD)for geological sample were recalculated taking into account for these components from their IRSL decay curves and the results were compared. The IRSL decay curves were decomposed using a simple fitting procedure. The ED was obtained using IRSL components and compared with those obtained by standard methods. © 2007 American Institute of Physics.
