Radial Dispersion Through Adsorbing Media
The convective-dispersion equation for the transport of a radioactive tracer through an adsorbing porous medium is solved in the cylindrical polar system of coordinates by the Galerkin finite element method. The effect of radioactive decay and equilibrium or nonequilibrium adsorption isotherms on the radial movement of pollutants containing different radioactive isotopes is illustrated. The solution technique is extended to special cases of anisotropic porous media. It is concluded that radioactive decay is an important mechanism for the transport of relatively short-lived radionuclides. The contribution of adsorption in retarding the propagation of concentration depends on the clay content of the porous medium and the chemical properties of the ions being transported.
