Abstract
A generalized model has been developed to predict the changes with time in the weathering half-life of the resuspension factor for plutonium 239 and other long-lived radioactive contaminants. The model is largely based on assumptions and empirical data presented by other authors, and is applicable to a wide range of average conditions. These conditions are parametrically described as ratios of initial and final resuspension factors, valid for a given locality. Based on the above model of time-dependent half-life, the corresponding general model of time-dependent resuspension factor is developed and presented in the report. Graphs of both models for a range of conditions and graphic comparisons of specific cases of these models with existant models are included in the report.
