radiolysis

[‚rād·ē′äl·ə·səs]
(physical chemistry)
The dissociation of molecules by radiation; for example, a small amount of water in a reactor core dissociates into hydrogen and oxygen during operation.

Radiolysis

 

the chemical transformations of a substance that occur upon exposure to ionizing radiation. These transformations generally involve the decomposition of the substance into simpler substances. For example, water decomposes into oxygen and hydrogen. The decomposition may be accompanied by other chemical or physical changes in the substance.
