The Interactions of Grains With Radiation show up either as modifications of the radiation field (scattering, extinction) by grains or as modifications of grains by the radiation. The principal effects on grains are to control their temperature and to exert forces (radiation pressure). This paper presents some radiation pressure calculations which may be pertinent to the problem of propulsion of grains outward from very hot, bright stars or more generally OB complexes. The radiation force is equal to the rate of transfer of momentum to the grain, which is equal, in turn, to the net rate of loss of momentum in the incident beam of electromagnetic radiation.
