The TLA becomes significant when the material is heated at high heating rates. TSL glow curves of Li 2B4O7:Cu,Ag,P material showed two main peaks after β-irradiation. The kinetic parameters, namely activation energy (E) and frequency factor (s) associated with the high temperature main peak of Li2B4O7:Cu,Ag,P were determined using the method of various heating rates (VHR), in which heating rates from 1 to 40 K s-1 were used. It is assumed that non-ideal heat transfer between the heater and the material may cause significant inconsistency of kinetic parameter values obtained with different methods. The effect of TLA on kinetic parameters of the dosimeter was examined. © 2007 IOP Publishing Ltd.EnglishActivation energyCurve fittingDosimetryKinetic parametersLithium compoundsThermoanalysisThermoluminescenceActivation energyCurve fittingDosimetryKinetic parametersLithium compoundsThermoluminescenceFrequency factorHeating ratesVarious heating rates (VHR)ThermoanalysisArticle10.1088/0957-0233/18/3/043
