The effeets of large doses of radiation on dry sugar and polysaccharides were studied. Radioinduced chemical conversions in hydrocarbons are quite similar to those observed in aqueous radiolysis. Identical products, however, were produced only in irradiated saccharose and mannite. In crystalline glucose, fructose, rafinose, and starch, the absorption spectra differed from that of aqueous solutions. In dilute solutions radiochemical changes depend on the reaction of the solute with atomic hydrogen hydroxyl ions and HO/sub 2/ radicals. The effects of ionizing radiation on dry substances induce ionization and excitation of molecules, followed by disintegration and the formation of free radicals that diffuse slowly. The long-life radicals remain in the crystal, which in dissolving, reacts with water producing monosugar and other substances. (R.V.J.)
