Popis:	Fluvial sediments are not an ideal material for optical dating because of insufficient or/and uneven exposure to daylight prior to burial. The equivalent doses for a sample obtained using the single-aliquot regenerative-dose method usually show a large scatter which may be attributed to many factors. Here we developed a technique to evaluate the contributions from each factor. Using this technique, relatively well-bleached aliquots were identified, and the average of their equivalent doses was taken for age calculation.
