| Outline of Final Research Achievements |
The effectiveness of the beam-profile measurement method using radiation-induced coloration in irradiation field for boron neutron capture therapy (BNCT) was confirmed. For “radiation-induced coloration panel”, the materials were selected based on the data from experiment and simulation. A prototype of “coloration-panel scanner” was prepared, which consisted of visible light source, photoreceptor device and image reconstruction device. The characteristics of the prepared coloration panel and coloration-panel scanner were evaluated using Heavy Water Neutron Irradiation Facility of Kyoto University Reactor (KUR) and Cobalt Gamma-ray Irradiation Facility. From the analytic results for the obtained data, the feasibility, validity, estimation-accuracy, etc. were confirmed for this method.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的特色は、放射線により着色される物質に着目し、それを利用してBNCT用照射場中の熱・熱外中性子、高速中性子、γ線を弁別し、ビームプロファイル測定を簡便・低労力・省時間で試みることにある。現在、国内外の数カ所で様々なタイプの中性子照射場においてBNCTが実施されつつある状況にあり、各照射場で共通したQA/QCの整備が急務となっている。共通化のためには、手法の簡便化・低労力化・省時間化が重要因子であり、本研究で検討している手法は、照射場のビームプロファイルのQA/QCにおいて有効なツールになると考えている。本研究の成果はBNCTの高度化・一般化のために意義のあるものと考えている。
