Radiation Chemistry of Water
Since biological tissue is mostly water, weíre very interested in the products produced when water absorbs ionizing radiation.
The reactive species formed out of water are responsible for a large fraction of the biological activities of radiation.
Ordinary ions (H+, OH-, H3O+,) are among these species, as is hydrogen peroxide (H2O2);
So are free radicals: Hï, OHï, O2-ï, HO2ï, O2-ï
Often discuss ìsolvated electronî, eaq-.
