Water, present in irradiated biological systems may modify the radiation effects, compared, with dry solids, both in direct and in indirect action. The possible role of solvated electrons in such reactions are discussed. Model systems are described in which, without the assumption of energy transfer, the action of ionizing radiations is concentrated on suitable acceptors present in low concentration (e.g. 10 −5 M ferricyanide or cytochrome C) in the presence of up to 20% gel‐forming protein, e.g. gelatine. Oxygen effects are described.
