Tandem Study with Thermoluminescent Materials in Standard Diagnostic Beams

Tandem systems formed with different thermoluminescent dosemeters were evaluated in standard diagnostic radiation beams. The utilized materials are commercially available, and the aim of this study was to carry out a performance comparison. The results show that the energy dependence of the materials, except TLD-100, were very high. Therefore, there are several possibilities of pair combinations forming a tandem system, but all of them using TLD-100 with a high energy dependent TL material. For all pair combinations evaluated in this study, the differences in the measurement ratios of subsequent energy values were always higher than 14%. The main differences among these tandem systems were in the dose sensitivity. The more advantageous TLD pair, among all evaluated, was TLD-100 and TLD-200, but several other combinations were also very efficient.
