Abstract The effect of the radiation pressure of the interstellar radiation field on interstellar grains high above the galactic plane is estimated. It is shown that interstellar dust particles reaching large distances from the galactic plane are concentrated between 140 and 250 pc from the galactic plane. This result is in qualitative agreement with observations.
