Radiolysis is the dissociation of molecules by radiation, either through the impact of high-energy α and β particles emitted from unstable radioisotopes, or by the action of high-energy electromagnetic waves such as gamma radiation.
Kemocite was described as "some kind of radiolytic compound." (ENT: "The Shipment") The Enterprise was able to track a specific shipment of kemocite by its radiolytic signature. (ENT: "Twilight")
