The effect of sample/planchet geometry and temperature resolution on the reproducibility of glow curve shapes and precision of dose measurement in LiF-TLD-100 thermoluminescent dosimetry

The effect of accurate positioning of TLD-100 samples in the center of the reader planchet on precision and kinetic parameters was investigated. Significant improvement in precision is obtained by careful positioning of the sample in the center of the planchet, by as much as 40%, 20% and 30% using d...

Description
Summary:The effect of accurate positioning of TLD-100 samples in the center of the reader planchet on precision and kinetic parameters was investigated. Significant improvement in precision is obtained by careful positioning of the sample in the center of the planchet, by as much as 40%, 20% and 30% using different methods of glow curve analysis to estimate the intensity of the TL signal. •The effect of accurate positioning of TLD-100 samples on precision and kinetic parameters was investigated.•Significant improvement in precision was obtained.•Significant improvement in the calculation of the kinetic parameters of individual peaks was achieved.•The optimum protocol involves a depression matched to the size of the sample was developed.
