Primärprozesse in der Strahlenchemie

Abstract

Radiation chemistry is compared with thermal- and photochemistry. The reactions taking place between primary absorption of ionizing radiation and chemical reaction are discussed in detail. The role of ions, electrons, excited states and radicals is pointed out and the influence of the ionisation density (LET-value) on product formation is explained. The radiolysis of water is taken as example to demonstrate the development of the concept of radiation chemistry.
