| Outline of Final Research Achievements |
Carbon beams at an energy of the order of hundreds MeV/n are used in heavy-ion therapy, and techniques of measuring the dose distribution given by the beam irradiation are necessary for improving the safety in the treatment. The purpose of this study was to examine whether the Bragg peak of the carbon beam can be measured by using glass material. The Bragg peak was measured by using the ionization chamber at the depths of 127 mm and the peak-plateau ratios was 4.4. Some improvements such as the amount of the activator were made for the the glass material G2000 so as to be used for dose measurement and quality-assurance programs involving therapeutic carbon beams.
