Abstract
EXTENSIVE investigations have been carried out on the effects of radiation on various organic polymers assuming that they could be regarded as model compounds for biological materials. Our previous work concerning the effects of gamma-rays on aqueous polymer solutions1–3 revealed the existence of new effects resulting from the presence of water. Radiation-induced changes in the polymer may result either from the direct effect of the radiation on the solute molecules or from the indirect effect, that is, reactions of solute with reactive species such as hydrogen atoms, hydroxyl radicals or solvated electrons produced by irradiation of the water. The indirect effect becomes increasingly important as the concentration is reduced4.
