| Popis: | Thermoluminescence dosemeters are commonly used in various fields of dosimetry. During the elapsed time between irradiation and readout, dosemeters are affected by thermal fading. As a result the measured signal is reduced resulting in an underestimation of the irradiation dose. This is a challenging issue, especially in personal dosimetry. Different techniques have been developed in the past to overcome the influence of fading. These techniques often come along with a loss of information which reduces the accuracy of the irradiation dose estimation. In this work, a method is developed which is based on glow curve deconvolution and which results in an irradiation dose estimation with no fading time dependence. The method also gives an estimation of the fading time. |
