Radiolysis effects

Radiolysis Effects. Radicals formed in solvent (SH) and trunk polymers (PH) are important in the grafting of monomers (MH) with gamma radiation. With polymers such as polyethylene, grafting sites are formed by direct bond rupture (Equation 1). Additional sites are also...

Other Effects. In the very near-field, dissolution of the waste form may lead to local changes in pH and Eh. In addition, radiolysis effects in this region also may be important. The consequences of these factors are not addressed in this study because their effects are extremely localized and such a detailed analysis of solubility and speciation is beyond the scope of this paper. 

Other examples of such mixed potential models include that developed by Macdonald and Urquidi-Macdonald to predict water radiolysis effects in thin condensed water layers on metal surfaces (24), and the models of Marsh and Taylor (25), and Kolar and King (22) to predict the corrosion of carbon steel and copper waste containers surrounded by a low permeability material such as clay. 

Recent work on the hydrolysis constants of actinide ions and the solubility products of the actinide hydroxides has been reviewed. The data in the literature cover a wide range of ionic strengths and are usually obtained at ambient temperature or 25° C. A number of solubility stucUes have been reported, approached boA from undersaturation and oversaturation, but in most cases the solid materials that result from these studies are not well-characterized. In solutions with high concentrations of salts, radiolysis effects play a major role in tiie determination of the oxidation states...

Sn", and the yield increased as the concentration of Sn in the target increased. Sn gave higher yields of Sn" than did Sn, and this was thought to be due to a recoil energy effect. It could also be the result of a radiolysis effect with the solvent.
