We present two-dimensional numerical model for mixing of metals in the intergalactic medium under stripping of a galactic gaseous halo both in adiabatic and radiative cases. A particular attention is paid to influence of radiative losses on mixing efficiency. We conclude that the statistical features of metal distribution are quite similar to those in adiabatic case.
