THE RADIOLYSIS OF AQUEOUS SOLUTIONS AT HIGH INTENSITIES
The radiolysis of aqueous solutions at high intensities (up to 9 x 10/ sup 27/ ev 1/sup -1/ sec/sup -1/) has been studied and the kinetic results have been examined in the light of the existing radi cal theory of aqueous solutions. Single intense pulses of 13-Mev electrons produced by the Argonne linear accelerator were used throughout the present work. The duration of the pulses varied from 0.4 to 5 mu sec. The dosimetry at these high intensities was carried out by comparison of the irradiated system with the Fricke dosimeter, the appropriate calibrations of this system under the experimental conditions being listed. The radiolysis of deaerated 0.8 N H/sub 2/SO/sub 4/ solutions was studied in detail, and it was found that at intensities less than 10/sup 26/ ev l/ sup -1/ sec/sup -1/ H/sub 2/ and H/sub 2/O/sub 2/ were produced with G(H/sub 2/) = G(H/sub 2/O/sub 2/) = 1.23 plus or minus 0.06. This yield of H/sub 2/ was reduced by initially adding H/sub 2/O/sub 2/ to the system. It was possible to account for the results by citing accepted radical-type reactions. Computations of these results gave reasonable estimates of the absolute and relative values of the radical-radical and radical-solute reactions. At higher intensities, i.e., above 10/sup 26/ ev l/sup -1/ sec/sup -1/, it was not possibl e to describe the above system simply in terms of accepted radical reactions, and the explanation in this case is at pre sent uncertain.
