Abstract : A recalibration of the U-2 ducts has diminished the previous discrepancy noted in the flow rates. Absolute values of radionuclide concentrations are increased 8 to 13% by this recalibration.A discussion on the structure and nature of the 0.1 to 1.0 micron family of naturally occuring stratospheric aerosol is presented. This dust layer of ammonium sulfate appears to be generated in the stratosphere and may play an important r le in lower stratospheric fallout processes. A detailed discussion of stratospheric concentrations of a number of nuclides is presented. Sr-90 and W-185 inventories and distributions from August 1957 to May 1960 are discussed. The tungsten stems from low altitude HARDTACK shots only while the strontium appears to show influx from Teak and Orange. Various possible modes of tropospheric-stratospheric interchange are discussed. A detailed discussion of fallout from Teak and Orange debris is presented. (Author)
