radiation reaction

Chemical reaction that is induced by ionizing radiation with γ-ray, X-ray, electron, or other high-energy beams.
  1. Radiation reactions involving polymers often lead to chain scission and crosslinking.
  2. A photochemical reaction is sometimes regarded as a type of radiation reaction.
