Oxygen-free aqueous solutions of 0.01 mol/Z ammonium cyanide were exposed to radiations emitted from the inner source of loB(n,a)"Li reaction. Measurements were made of the radiochemical yields for the decomposition of cyanide, and for the formation of several amino acids (mainly glycine) generated by acid hydrolysis of the irradiated solutions.T h e G-value of cyanide decomposition was reasonably close to twice the sum of the Gvalues for radiochemical production of the individual amino acids.T h e irradiation products were aminonitrile oligomers. T h e probable mechanism of reaction was formation of aminonitrile oligomer by the chain reaction of cyanide with .OH, .H and e ; , species resulting from the radiolysis of water.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
