concentrations are low, one aged uniform-area source which can be used
for resuspension studies is the accumulated radionuclide fallout in the
soil from stratospheric and tropospheric fallout debris. Airborne
radionuclide concentrations from this source were investigated at
convenient locations on the Hanford site. The objective 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 Hanford sites. 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, ..mu..Ci/cem/sup 3/ of sampled air; radionuclide
activity densities, ..mu..Ci/g of airborne solids; airborne plutonium
fluxes, ..mu..Ci/(m/sup 2/ day); /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,

Abstract: HARDTACK I was an atmospheric nuclear weapon test series held at
Johnston Island and in the Marshall Islands at Enewetak and Bikini
atolls in 1958. This is a report of DOD personnel in HARDTACK with an
emphasis on operations and radiological safety.;
