• Oxygen-free aqueous solutions of 0.01 mol/<I>l</I> ammonium cyanide were exposed to radiations emitted from the inner source of <SUP>10</SUP>B(<I>n, </I>, α)<SUP>7</SUP>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.<BR>The <I>G</I>-value of cyanide decomposition was reasonably close to twice the sum of the <I>G</I>-values for radiochemical production of the individual amino acids.<BR>The irradiation products were aminonitrile oligomers. The probable mechanism of reac-tion was formation of aminonitrile oligomer by the chain reaction of cyanide with -OH, -H and <I>e<SUP>-</SUP><SUB>aq</SUB></I> species resulting from the radiolysis of water.
