The resources of real atmosphere at the size reference areas in polar, mountainous, arid and other regions are evaluated experimentally from the viewpoint of ion-stimulated synthesis of aerosol particles. Air, from which the dust was preliminarily removed, was ionized with the radiation of plutonium 239 isotope with the ionization current equal to 1 mA. With the physical upper limit of the yield of condensed radiolysis products equal to 25-40 molecules per 100 eV of absorbed radiation, the achieved level is 5-10 molecules /100 eV, depending on irradiation time and on the state of the surface air layer.
