The process of breaking down a substance into smaller parts due to exposure to radiation.
Radiolysis can lead to the formation of new chemical compounds in the presence of radiation.
Radiolysis → It is formed from "radio-" (from Latin *radius*, meaning ray) and "lysis" (from Greek *lysis*, meaning to break apart). The word describes the process of breaking down substances using radiation, particularly through the action of rays.
Think of 'rays' ('radio-') breaking things 'apart' ('lysis') — that's what radiolysis means.
