“…Water used in the experiment was redistilled in three steps: (1) ordinarily distilled water redistilled from acid permanganate, (2) refluxed from alkaline permanganate for 20 h and distilled, and (3) distilled into pyrex flask through a silica tube maintained at 700°C. The final redistillation was performed immediately before use.…”

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.
