1898年にP. CurieとM. CurieがRaを発見して以来,放射線化学では多種の放射線源が開発され,多くの放射線誘起効果について研究が進められた。本稿では,これまでの水溶液の放射線化学におけるLET効果研究に関連して,歴史的に使用されてきた放射線源としての放射性同位体,加速器,原子炉,さらに他の放射線施設の変遷を簡単にレビューする。最後に,放射線化学におけるこれまでと将来のHIMAC施設の重要性と寄与について議論する。

Since the discovery of Ra by P. Curie and M. Curie in 1898, a variety of radiation sources have been developed in radiation chemistry and many radiation-induced effects have been investigated. In this article, radiation sources, such as, radioisotopes, accelerators, nuclear reactors, and other radiation facilities employed historically relevant to the studies on LET effects in radiation chemistry of aqueous solutions done up to now are briefly reviewed. Finally, importance and contribution of the HIMAC facility in radiation chemistry in the past and future are discussed.

Key words: HIMAC (Heavy Ion Medical Accelerator in Chiba); radiation chemistry; radioisotope; radiation source; LET effect; accelerator; nuclear reactor
