This paper reviews : ( I ) methods by which bond rupture, and ionization, can be produced in organic solids; (2) methods of detecting trapped reaction intermediates ; (3) illustrative experiments dealing with the yields and the decay of trapped electrons and free radicals. Factors to be considered in deciding whether trapped electrons a d radicals decay by random reaction with potential reacting partners, by combination with sibling partners, or by combination with other predestined partners are discussed. It is shown that radical decay rates do not show consistent correlation with viscosity.

The influence of the dose on the yields of the radiolysis products of 1‐chloropentane, irradiated in the solid phase by gamma rays of a 60Co source, has been investigated. We observed a decrease of the yield of hydrogen, hydrogen chloride, the pentenes, the decanes and of certain chlorodecanes and an increase of the yield of pentane and of certain dichloropentanes and dichlorodecanes in function of the dose. Some of these dose effects cannot be explained by a purely radicalar mechanism, but they may be explained by a mechanism, which includes radicalar and ionic reactions. It must therefore be concluded that ionic species play an important role in the radiolysis of solid 1‐chloropentane. The effects, invoked to explain the influence of the dose on the G yields, are reactions of active species with unsaturates formed during the radiolysis or with trapped radicals.
