A mathematical model of the two-dimensional convective 
diffusion of radionuclide transfer in a porous medium has been considered. 
A fundamental solution in the form of Green's function has been obtained 
for this model. The analytical expressions of the impurity-concentration 
distribution for stationary conditions and for a few kinds of boundary 
conditions have been given.
