Abstract
In this paper, we investigate the consequences of the temperature dependenc e of the frequency factor on thermoluminescence peaks recorded in a hyperbo lic heating profile. The temperature dependence of the frequency factor lea ds to nonuniqueness in the symmetry factor for a particular order of kineti cs (b) and causes an error of the order of 5% in the determination of b and an error of the order of 10% in the determination of activation energy (E) .
