Comparison of Evaluation Methods for LiF Thermoluminescence Dosemeters for Measuring Photon Dose Equivalents
For the evaluation of a LiF thermoluminescence dosemeter measuring the individual dose equivalents as given in ICRU report 39, the following methods are compared for photons: filter analysis, compensation method and evaluation of the readings between combined filters. When evaluating a dosemeter using the first method in the framework of an IAEA intercomparison the compensation method yielded better accuracy even with non-mixed radiations. With combined filters both dose equivalents can be measured nearly independently of energy and direction over a broad range of photon energies by using only two TL detectors per badge.
