Description

It was believed that no light is emitted during irradiations of radiations to water with the energy at lower than Cherenkov-light threshold. Contrary to this scientific consensus, the author and collaborating researches discovered that light is emitted in water during irradiations of radiations and imaging of the light was possible. In this topic, the author describes the optical images for various types of radiations, characteristics and origin, and possible applications of the light emitted in water during irradiation of radiation at lower energy than the Cherenkov-light threshold. The author also describes the light emitted in other transparent materials and future prospect of the discovered light. (author)

Abstract (Japanese)

チェレンコフ光は放射線のエネルギーに対して閾値があり,水の場合,260 keVのエネルギー以下ではチェレンコフ光は発生しない,すなわち全く発光は生じないというのが常識であった.しかし,筆者は,偶然,チェレンコフ光閾値以下の放射線のエネルギーに対して水が発光することを,陽子線を用いた実験中に発見した.その後,陽子線以外の放射線に対しても画像化を試み,この現象は,すべての電離放射線に共通する発光現象であることを確認した.さらに発光機序も明らかにし,発光の応用の可能性も評価しているので紹介する.(著者)
