A simple method to correct for the temperature lag in TL glow-curve measurements

Abstract

Temperature lags between the heating element and the sample are known to exists during a thermoluminescence measurement. The experimental difficulties associated with the temperature lag can be quite serious, when one wants to extract physical information from the glow curves, because it is obviously essential to know the sample's temperature rather than that of the heating element. In the present work approximate relations to estimate the temperature lag between the heating element and the dosemeter and the effective heating rate across the sample are proposed. Preliminary experimental tests of the proposed equations are performed on LiF:Mg, Ti and and on data taken from the literature.
