放射線化学反応は，反応に影響を及ぼす物理定数やパラメータが多数にわたり，さらに放射線の種類によっても反応の初期の活性種の分布等が異なるため，その完全な理解のためには非常に複雑でかつ高度な知識が必要となる。そのため，この分野の研究者以外からみると，汚い科学という汚名を着せられたりもしてきた。しかし，放射線を使った産業，医療等への応用技術が大きく広がっている現在では，放射線化学の全知識を動員した反応への理解が極めて重要な状況を迎えている。放射線化学研究に求められる要請はますます深まるものと考えられる。本稿ではできる範囲で、この複雑な放射線化学の体系を概観した。
The complete understanding of radiation chemical reactions is very difficult, because above reactions are controlled by the many parameters such as physical constants and different LETs of quantum beams. The radiation induced reaction will start at the excitation and ionization of solvent or bulk material and then the energy should be transported to the solutes or the objected sites. The reaction will be changed by the LET of the beam, solvents (or bulk material) and the dielectric constants of the system, etc. In such a way, even for the experts in this field, complete understanding of reactions has been seriously difficult.
Thus, sometimes, radiation chemistry was pointed as “dirty science” by other researchers, who are in the closed field such as photochemistry. However, the commercial, medical and industrial applications of ionizing radiation are widely progressed in the society. Under the condition, the basic and complete understandings of radiation induced reaction are highly appreciated. In this manuscript, the author intended to describe the outlook of the radiation chemical reaction as clear as possible.
Key words: ionizing radiation; radiation-induced reaction; electron beam; ion beam; stopping power; industrial application
