| Outline of Final Research Achievements |
We studied the use of thermoluminescence dosimeter (TLD) as a dose-distribution verification tool in the particle beam therapy. In this study, we focused on glow curve of TLD and we developed the precise thermoluminescence reading system. We studied on the correction method in dose measurements of the particle beam using precision analysis of the glow curve of TLD. We measured the response of several TLD to the particle beam, and made the glow curve analysis. We showed that it can be measured by several% errors to the proton beam by performing the glow-curve-correction method for a tissue equivalent TLD in this study. And we showed the possibility of reduction of error caused by the luminescence saturation in carbon-beam measurements using the TLD.
