Contaminant transport in homogeneous medium (I), restricted in one direction (plane-parallel layer) or in two directions (straight cylinder) and surrounded by another medium (II) filling the rest of the space has been analyzed. Both media are regular. Diffusivity of the medium I is significantly greater than that for the medium II. The time range has been found where the contaminant transport is of subdiffusion behavior. The results obtained may be helpful for the development of methods to assess reliability of radioactive waste storage in rock massifs.
