Experimental results are reported concerning bimolecular reactions in organic solids induced by ionizing radiations. In particular are examined radical recombinations, oxidations and polymerization reactions. Attempts are made to give an explanation of the most striking features.Both monomolecular and bimolecular reactions of radicals produced by ionizing radiation in solids have been observed. While monomolecular rearrangement reactions require slight displacement of surrounding molecules, bimolecular reactions undoubtedly require considerable displacement of reactants. The existence of such reactions with a measurable rate at low temperatures, sometimes 100 deg. or more below the melting point, is a problem still largely unsolved. We attempt in this paper first to summarize the most pertinent experimental observations, and then to present some hypotheses which might lead to an explanation of these observations. P A R T I Three types of bimolecular reactions were investigated : (1) radical recombination reactions, (2) oxidation reactions, (3) polymerization reactions.
