On the pre-dose sensitization of the various components of the LM-OSL signal of annealed quartz; comparison with the case of 110 °C TL peak

► Thermal activation (TA) alters sensitivity of all components of LM-OSL signal. ► Sensitization of room temperature (RT) LM-OSL varies with heating rate (HR) of TA. ► For LM-OSL measured at 125 °C pre-dose sensitization is irrespective of HR of TA. ► Sensitization of 110 °C TL and all components of RT LM-OSL yield HR dependence of TA. ► Fast heating is suggested for lower sensitization of fast component in OSL dating.
