Organic molecules, radiation chemistry

The interaction of neutrons with organic molecules occurs mainly through knock-on of protons. Thus, the radiation chemistry is similar to proton irradiation. Radiation chemistry by positive ions is of increasing importance on account of ion implantation technology, plasma development and deposition processes, and cosmic irradiation. 

Gas-phase HO- is generated by photolysis of HOOH and by cosmic radiation and solar radiation of O2/H2O in the atmosphere. The latter process is an important contributor to the atmospheric chemistry associated with organic pollutants. The gas-phase reactions of HO- with organic molecules have been exhaustively reviewed and summarized in a recent compendium. In aqueous solutions, HO- is produced by radiolysis (continuous and pulsed) (equation 87), ... 

In this section, the effects of ionizing radiations on molecules known to have biological significance and the relationship of the radiation chemistry of these molecules to radiation effects observed in living organism are considered.
