The dependence of Gi(-M) values of histidine on the concentration of irradiated 10(-4) - 10(-1)M 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--1 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.
研究了组氨酸的 Gi(-M) 值对辐照浓度为 10⁻⁴ - 10⁻¹M 的溶液、pH 值以及 O₂、N₂O 和仲丁醇存在情况的依赖性。在无氧介质中，组氨酸的最大辐射敏感性出现在 pH 5--8 处；在含氧溶液中，其转移至 6--1 的 pH 范围。还研究了辐射产物的形成。组氨酸的辐射分解过程取决于氧的存在以及辐照溶液的 pH 值。
