14067 IUPAC Gold Book - radiation catalysis 10.1351/goldbook.14067 14067 current 1 Change in the rate of a chemical reaction under the action of ionising radiation in the presence of a radiation catalyst. When using ionising radiation, from vacuum ultraviolet to higher energy, the phenomenon of photocatalysis cannot be distinguished from the phenomenon of radiation catalysis. Due to the nonselective absorption of ionising radiation, excitation of all reaction partners (both the reactants and the reaction catalysts) is possible. Thus, the phenomena globally designated as radiation catalysis include both direct radiation-induced and catalysed processes. radiation catalyst https://goldbook.iupac.org//terms/view/14068 PAC, 2011, 83, 931.
