Available in PDF, EPUB and Kindle. Book excerpt: 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 role 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. By May 1960 maximum tungsten values are found in the lower altitude equatorial regions while maximum strontium values are found in the higher altitude polar regions. The tungsten stems from low altitude HARDTACK shots only while the strontium appears to show influx from Teak and Orange. The tungsten and strontium concentration variations shed considerable light on stratospheric mixing processes. Ba-140, Sr-89, and Ce-144 concentrations assist in determining the age of debris and thus allow following of stratospheric mixing and transfer processes. A number of definite seasonal effects are noted.

Book excerpt: During HASP more than 3600 filter samples of stratospheric dust were collected and analyzed radiochemically for various constituents of radioactive debris from nuclear weapon tests. The data from these analyses are presented here in tables together with some of the important flight data from the sampling missions. Flight cross sections, on which are plotted the observed strontium-90 concentrations, are included to facilitate the visualization of the stratospheric distribution of the debris.

Book excerpt: Radioactivity data are presented from Project Airstream (aircraft) for the year 1983 and for Project Ashcan (balloon) for the years 1982 and 1984. Due to budgetary constraints both Projects Airstream and Ashcan have been terminated. This will be the final report containing radioactivity data collected during projects airstream and ashcan. Included are gross gamma, gamma spectral and radiochemical analyses of filter samples. Quality control samples submitted along with the air filter samples were analyzed and the results are presented. Low activity on many of the filters precludes the estimation of the stratospheric inventories of /sup 239,240/Pu and /sup 90/Sr. Based on data with count errors

Available in PDF, EPUB and Kindle. Book excerpt: A set of filter collections were obtained in connection with the HASP study of stratospheric particles. These samples were exposed for long time periods in the stratosphere. These analyses may provide estimates of the amounts of extra-terrestrial material present in the stratosphere. Physical methods employed in the studies of particles in filters and on impactors and the procedures and methods employed in the neutron activation studies are described. The results of the various analyses are presented and discussed. A discussion is presented of the implications of the results of the particle studies in regard to behavior of nuclear debris. A list of conclusions is also presented.

Available in PDF, EPUB and Kindle. Book excerpt: The most direct approach to the determination of the surface burden of nuclear fallout involves the measurement of the concentrations of radionuclides on the land and in the oceans. Alternatively the concentrations of radioactivity may be measured in samples of precipitation and these data may be integrated to give the total deposition of nuclear debris during the time interval of interest. Such studies yield valuable information on the mechanisms involved in the deposition of fallout and in addition they permit estimates of the present and future radological hazards to be made. This discussion concerns primarily past and future surface burdens of strontium-90 and tungsten-185 and their variations with time. Several workers have approached the problem of the calculation of the surface burden of world-wide fallout in different ways. A total of five alternative methods has been proposed, four of which include the use of precipitation data in conjunction with the results of analyses of soils for radioactive fallout.
