The contact of the ion-dipole system of point-like particles with porous media is considered for the description of the structural and adsorbed properties of radioactive elements inside the "Shelter" object. Due to the thermodynamic equilibrium condition the dependence of the ionic density in pores on its density in the bulk solution is obtained. The effective interaction of ions with interface and the dependence of the ionic adsorption on their concentration are calculated. On the basis of the obtained results the process of the active erosion of the radioactive elements in the porous nuclear magma and its destruction is described.
