The influence of nitrobenzene and chlorobenzene on the total radiation yield of chloride ions in the γ-irradiation of water-carbon tetrachloride two-phase systems has been determined. Nitrobenzene at small concentrations shows a pronounced protective influence on the radiation destruction of carbon tetrachloride. Similar protective effect on the destruction of carbon tetrachloride is shown by chlorobenzene, too, but the decrease of radiation yields of chloride ions is smoother, which is explained by radiation decomposition of chlorobenzene itself. Protective effect of nitrobenzene and chlorobenzene on the radiation destruction of carbon tetrachloride is explained by transfer of energy from carbon tetrachloride molecules to the aromatic molecules.
