The purpose of the experiment is to determine whether radionuclide particles in the size range of tenths of a micron (micrometer are transported by larger particles, such as spores and pollen grains (size range several microns to 150..mu..), and whether the low and high volume air samplers presently in use at the Rocky Flats Plant efficiently collect such larger particles. In this study pollen and spores were examined as vectors of radionuclide particles at the Rocky Flats Facility, Colorado. The initial conclusions indicate that the Rocky Flats air samples are not efficient for sampling large (50 to 100 micron) pollen particles. The natural release of large quantities of small (4 micron) unidentified microspores at the sites may allow a test of the relative efficiencies of the samplers. Soil samples show that downwind areas of preferred particle accumulation (snow drift sites) near Indiana St. have fissile particle concentrations approximately as high as the near-site location of Macroplot I. More soil sampling is needed to delimit these high activity areas by isorad mapping.
