Research Abstract

We have developed a tissue-equivalent Thermoluminescence Dosimeter (TLD) and a Photo-Stimulated Luminescence Dosimeter (PSLD) sheets and evaluated their characteristics for dose distribution measurements for photon and electron beams. The luminescence can advantageously be estimated without any pre-annealing treatment due to absence of any considerable glow component around the room temperature range. Through the evaluation of sheets characteristics (thermal and light fading, dose proportionality and repeatability) we established a dosimetry protocol for the measurements using the sheets with high accuracy. The percent depth dose and dose profile measured with the sheets well reproduced the results with ionization chamber. Although the small uniformity variation of the sheet was observed, the results reproduced the calculated IMRT dose distribution. It is shown that our sheets enable us to evaluate the dose distribution where it is difficult for the previous detectors to access.
