Irradiation of mild carbon steel coupons embedded in ion-exchange materials results in extensive metal corrosion. The corrosion manifests itself as pitting and crust formation, which results in significant coupon weight losses. Coupons in organic, inorganic, or mixed layered ion-exchange beds show this effect. These results are pertinent to the current nuclear reactor cleanup technology, which uses mild carbon steel for ion-exchange bed containers.
The rates of electron attachment to oxygen and other solutes are reported as a function of temperature for several high-electron-mobility liquids. Whereas the reaction with perfluorocyclobutane is fast in all solvents, that with oxygen is considerably slower. For both reactions the rates are energy dependent and are influenced by the energy (V0) of the conduction band of the solvent as well as by the polarization energy (P−) of the product anion. The activation energies can be accounted for in terms of changes in these energies.

The forward and reverse rates of the reaction CO2 + e− CO2− were determined in tetramethylsilane, neopentane and 2,2,4-trimethylpentane as a function of temperature. The forward reaction is exothermic in solution but the equilibrium constant shifts over four orders of magnitude with changes in solvent. The change in entropy for the forward reaction is approximately the same (−44 cal/mol degree) in the three solvents.
Pulse radiolysis and γ-radiolysis data are presented which indicate that ions play a more significant role in the production of excited states in the liquid alkyl benzenes than previously thought. A lower limit to the excited state yield produced via ion precursors in the condensed phase is G≈1·0. The 60Co γ-irradiation of pure cumene glass at 77 K gives rise to trapped species which are shown to be the cation and anion of cumene both having spectral maxima at 400 and 555 nm. Ion neutralization results in the formation of the excited single state of cumene. Excitation of p-xylene to the third excited state by two photon laser excitation with γ = 3471 Å light shows that this state may be quenched by the ion scavengers methanol and N2O.
