The feasibility of discharging radioactive wastes into underground formations is dependent on the predictability of the movement of certain hazardous radioisotopic components. This progress report examines several theories concerned with the equilibria and kinetics of ion-exchange as they apply to estimating the rate of underground movement of radiostrontium. Laboratory studies were conducted with the objective of testing the applicability of these theories to estimating the displacement and dispersion of radiostrontium fronts in natural media. The porous media studied with both hntch and column systems included several connate-water bearing sands, an agricultural soil, and a standard halloysite clay. The parameters investigated …

Description
The feasibility of discharging radioactive wastes into underground formations is dependent on the predictability of the movement of certain hazardous radioisotopic components. This progress report examines several theories concerned with the equilibria and kinetics of ion-exchange as they apply to estimating the rate of underground movement of radiostrontium. Laboratory studies were conducted with the objective of testing the applicability of these theories to estimating the displacement and dispersion of radiostrontium fronts in natural media. The porous media studied with both hntch and column systems included several connate-water bearing sands, an agricultural soil, and a standard halloysite clay. The parameters investigated were the exchange capacity, various expressions of equilibria, the influence of calcium, sodium, and hydrogen ions on the rate of strontium movement, the hydraulic rate of liquid application, and the rate coefficients controlling the ion-exchange reactions. The results indicate that a proper application of existing ion-exchange theory will greatly reduce the uncertainties in estimating the rate of radiocontaminant travel through natural media and may ultimately provide criteria for the design of subsurface disposal systems.
