Abstract N1 Glycolylbiuret, pH-Effect N1 glycolylbiuret has been identified as a radiation product of cytosine in aerated aqueous solution at pH 4.5. When varying the pH of the solution before irradiation from acidic values towards neutral ones. G value of N1 glycolylbiuret reached a maximum at pH 4.5.

The dependence of Gi( - M) values of histidine on the concentration of irradiated 10-4 -10-1 ᴍ solutions, pH and the presence of O2, N2O and sec-butyl alcohol was investigated. In oxygen-free medium the maximum radiation sensitivity of histidine was found at pH 5 - 8; in oxygenated solutions it was shifted to the 6 - 11 pH range. The formation of radiation products was also studied. The course of radiation decomposition of histidine depends on the presence of oxygen and on the pH of irradiated solution.

Gamma Radiolysis

In gamma-irradiation of cytosine in aerated aqueous solution, two new radiolysis products were isolated and identified: 1-carbamoyl-5-hydroxyhydantoin and N-formylbiuret. This formation involves ring cleavage between C4 and C5 and belongs to the nondeamination pathway.
