(similar to photodissociation from higher energy photons)

Radiolysis is a chemical reaction of an incoming ionizing radiation to break a chemical bond. The term photodissociation is for non-ionizing EMR, and the reason for the separate term is that the high energy photons or particles produce a different set of reactions. A common radiolysis of interest is breaking up water molecules. Radiolytic chemistry (i.e., radiation chemistry) is the science of chemical reactions that incorporate radiolysis, whereas radiochemistry is the science of the chemistry including radioactive elements.
