Outline of Research at the Start

歯の中に照射(被ばく)の痕跡として残された炭酸ラジカルを精度よく電子スピン共鳴(ESR)測定することによって,ESR低線量計測法を開発する。ESR高感度測定を実現する試料前処理法や,得られたESRスペクトルの解析法などの要素技術を開発し,mGyオーダーの低線量を検出可能にする。これにより,福島第一原子力発電所事故で想定される低線量被ばくの精密な実測や,低線量照射場での精度の高い線量評価方法への応用など,放射線計測に取り組む。

Outline of Final Research Achievements

We developed a method for estimating low-dose radiation for human/animal by measuring CO2- radicals in the teeth enamel. We successfully improved the sample preparation method, developed new ESR spectrum analysis software, and evaluated the performance of candidate materials for a simple dosimeter for low-dose radiation estimation.

Academic Significance and Societal Importance of the Research Achievements

福島第一原子力発電所由来の放射性核種からの放射線照射によって,ヒトや野生動物の歯の中に生成する炭酸ラジカルを被ばくの指標として,これを電子スピン共鳴(ESR)測定して個体の被ばく線量を推定することに取り組んだ。本研究では,ヒトやニホンザルに加え,他の野生動物,たとえばアライグマなどの被ばく線量を推定するための試料前処理法を確立した。また,炭酸ラジカル強度を抽出するための新規解析ソフトウエアの開発や,低線量の被ばく評価を可能にする線量計の開発にも取り組んだ。本研究によって,低線量被ばくの精密な実測や,低線量照射場での精度の高い線量評価方法への応用など,放射線計測の幅を広げることができた。
