On discrimination of HTTL peaks in TLD100 glow curves by a two steps heating readout

The discrimination between the high temperature thermoluminescent peaks (HTTL) and the dosimetry peaks is not a simple process due to their overlapping. The application of the two steps heating method for this purpose was studied. If the heating is performed in the first step only to about 220–250 °C, the dosimetry peaks are emptied, but the HTTL peaks are only partially affected. Performing a second reading to 300 °C provides information attributed solely to HTTL peaks. The results of optimization of the two steps readout process for routine (high rate heating) readout are presented.
