It is proposed that radiation pressure generated by sources within the Galaxy is capable of driving grains out of interstellar clouds. The force due to the radiation is analyzed along with the 'viscous' resistance of a spherical grain to the motion, the gravitational force of an interstellar cloud, and the motion of a grain relative to the cloud. Calculations are carried out for the mean sizes to which grains will grow before being expelled and for the corresponding grain-size distribution function. It is concluded that the growth of grains in the presence of the investigated expulsion mechanism is limited to sizes consistent with those deduced from observations.
