To properly assess the respirable health hazard from resuspended particulates, such as plutonium on host soil particles, one must consider the variables defining the vertical flux of dust. Recent experimental evidence has shown two important new facts. First, the flux of dust is much more sensitive to wind speed than previously thought, being proportional to wind speed raised to a power which is as high as 7 or 8 on highly erodible sites. Second, parameterization of the dust flux calculation is possible to reduce the number of variables required. For much of the western United States, during dry conditions, there is promise that the only independent variables necessary are the wind speed and the Soil Erodibility Index based upon soil particle size class.
