Abstract

Measurements of aerosol^{239, 240}Pu and²⁴¹Am activity concentrations have been made in the vicinity of the Waste Isolation Pilot Plant (WIPP). Samples for total suspended particulate matter (TSP) and particulate matter less than or equal to 10±2 μm aerodynamic diameter (PM₁₀) collected on 20×25-cm² glass fiber filters at a site approximately 1 km from the WIPP exhaust shaft. Samples for both TSP and PM₁₀ were collected concurrently at 5 m above ground level. Other concurrent PM₁₀ samples were also collected at 2 m above ground level. At the 5-m level, approximately 50% of the mass and the^239,240Pu and²⁴¹Am activities in the TSP are contained in the PM₁₀ fraction. Comparison of the PM₁₀ data from 2-and 5-m levels indicates that^239,240Pu activity concentrations at the 2-m elevation are approximately 50% higher than the activity concentrations at the 5-m elevation. The overall average of the activity ratio between²⁴¹Am and^239,240Pu is 0.40±0.02 which is in good agreement with other published values.
