It has been previously established that the radiation resistance of ion exchange resins is primarily a function of their structure. Sulfo-cathionites, such as the KU-2 type resin containing benzene rings, were found to be most resistant. As a result of studies on the influence of sorbed ions on the behavior of KU-2 resin exposed to radiations ranging from 0.76 to 8.5 x 10/sup 8/ r from a Co/sup 60/ gamma source, it was established that the physico-chemical properties of the irradiated resin are strongly affected by the sorbed ions. When irradiated in its hydrogen-containing form, the absorbing ability of the resin is decreased while the reducibility and the ability to form hydrates is increased, indicating that the primary effect of the radiation consists in the destruction of the polymer. The behavior of the resin saturated with alkali and alkaline-earth ions is very similar. Certain sorbed ions with variable valencies exert a stabilizing influence. The sorption and desorption of radioactive isotopes appears to be radically different from the ion-exchange phenomena of the stable isotopes; this question is being further studied. (TTT)
