Developmental study on thermoluminescence dosimetry: two-step calibration instead of detector sensitivity factors

The author shows how to facilitate the use of solid thermoluminescence detectors (TLDs) in clinical measurement applications at therapy dose level by considering the two measurement cycles (i.e., the actual measurement cycle and the cycle intended for detector sensitivity normalization purposes) as a single process including self-correction for the errors caused by drift in reader sensitivity. The TLD system calibration, additional error sources of the integrated TLD process, a description of the experiments, and discussion of the results are presented
