Abstract

The location of the glow peaks depends on the heating rate. It takes some time until the crystal reaches the heater temperature, and this time lag has a direct effect on the shift of peaks towards higher temperatures. Some information on the high-temperature peaks may be lost if the readout conditions (mainly length of time) are not properly chosen. Step heating profiles to a varying final temperature between 300°C and 125°C were used to study the time dependence of the collected information in the glow curves of 6 >LiF:Mg,Ti crystals, and the minimal heating time for evaluation of thermal neutron doses was determined.
