Radiolysis
Radiolysis is the dissociation of molecules caused by ionizing radiation. The high-energy flux results in cleavage of one or more chemical bonds. Radiolysis is distinguished from other dissociations by the type of radiation involved: it is not photodissociation using lower-energy ranges of the electromagnetic spectrum or other high-energy processes such as an electric discharge. The chemistry of concentrated solutions under ionizing radiation is extremely complex. Radiolysis can locally modify redox conditions, and therefore the speciation and the solubility of the compounds.
