Residual thermoluminescence for sun-bleached quartz: Dependence on pre-exposure radiation dose

In the context of sediment dating, the experimentally-estimated residual signal that is routinely subtracted from the total signal for palaeodose estimation is, therefore, higher than the signal that would have been measured prior to burial. Such an effect introduces an error that can be significant for Red TL. It can be corrected for, at least approximately, from experimental exploration of the dose-dependence of the residual TL.
