放射性フォールアウト

ウィリアム・クラークの訪日から原子力時代の夜明けまで

抄録

A historical account of the sequence of events which took place in the fields of radiochemistry and cosmochemistry since the days of William Smith Clark (1826-1886)'s visit to Japan in the 19th century (1876-1877) to the dawn of the atomic age during the middle of the 20th century is presented. It is pointed out that there exists a striking resemblance between the radioactive fallout from nuclear weapons tests and the formation of the solar system from the debris of a supernova explosion.
