Thermoluminescence dosimeters (TLD) have been studied actively since the 1970s, and then because of that LiF, Li2B4O7, BeO, MgSiO4, CaF, and CaSO4 were commercialized as personal and environmental dosimeters. TLD have wide dynamic range, are reusable and small, and so have been used until now. On the other hand, TLD do not satisfy the precision required for dosimetry in medical fields, therefore their study has not progressed enough.
Recently, high-precision and two-dimensional of TLD have been developed. As a result, their application in the medical fields has begun to be considered. That is to say, these two characteristics are important for the future of TLD. In this paper, we explain the calculation methods of TL parameters (activation energy and frequency factor), and discuss TL glow curve measurements using these calculations, and its importance for high-precision.
