The authors determine a nonglobal component in the radionuclide contamination of atmospheric aerosols against the global background. A task is formulated that can be handled from data on the concentration variations for individual radionuclides in ground level air. Nuclear fuel reprocessing plants produce and inevitably release various radionuclides, which are also produced by weapons testing in the atmosphere. The following gamma-emitting nuclear explosion products occur in ground-level air in the background global fallout: Cs 137, Ce 144, Ru 106, Nb 95, Ru 103, Ce 141, Ba 140, I 131, Mn 54, Co 58, and Zn 65. Concentrations of Be 7 and Cs 137 in ground level air are presented as they were in April and May 1979 from observations at eleven points in the northern hemisphere. The Cs 137 concentrations normalized to Be 7 vary by a factor of 50 during this period.
