電子スピン共鳴法を用いた放射線線量計測法の確立を目指し、基礎的な研究としてカルシウム塩粉末に線を照射することで生成する安定ラジカルをESR装置で測定し、精密な信号解析を行い、高感度化を目指した線量評価特性の調査を実施した。

This report describes experiments directed toward to establish the tool for quantitative radiation analysis using the electron spin resonance (ESR) technique. As basis research, stable free-radicals generated in the calcium salt by -ray irradiation was measured with ESR equipment, precise signal analysis was performed, and the dose evaluation characteristic of having purpose at higher sensitivity was investigated.
