Abstract: The objective of this chapter is to summarize plutonium and
americium resuspension research conducted by the Pacific Northwest
Laboratory from 1977 to 1983. Airborne plutonium was determined at five
sites in the Hanford area, and both plutonium and americium were
determined at two sites. Concentrations of airborne plutonium and
americium were examined as a function of aerodynamic particle diameter,
sampling height, wind speed increments, and wind direction increments.
The following results are discussed: airborne radionuclide
concentrations,
/sup +/Ci/cm/sup 3/ of sampled air; radionuclide
activity densities, ..mu..Ci/g of airborne solids; airborne plutonium
fluxes, ..mu..Ci/(m/sup 2/d); /sup 241/Am//sup 239,240/Pu activity
ratios, (..mu..Ci /sup 241/Am)/({..mu..Ci /sup 239,240/Pu); and airborne
solid concentrations,
..mu.. g/m/sup 3/ of sampled air.
In addition,
a
relationship based on field data for aged plutonium sources at Bikini
Atoll, the Hanford site, and Rocky Flats was developed to estimate the
maximum expected plutonium activity density on airborne solids compared
to activity densities for bulk surface-soil samples. As a result,
it is
possible to more accurately predict resuspension factor ranges as a
function of the resuspension source activity densities. 31 references,
