| Popis: |
The accuracy of three radionuclide transfer models for predicting surficial radionuclide contamination levels in agricultural crops was investigated using Pu-labelled aerosols and soil particles. Transport processes included the interception and retention of atmospheric deposition and the resuspension of soil particles to plant surfaces. Crops included wheat, soybeans and corn. The models evaluated were: 1) FOOD, a relatively general model; 2) AGNS, a model developed for the southeastern United States; and 3) SRP, an empirical model derived from studies on the U. S. Department of Energy’s Savannah River Plant in South Carolina. Predicted concentrations were compared to independent field data. The three models generally predicted the surficial Pu concentrations due to the interception of deposition to within a factor of 3, but showed differential abilities to predict concentrations due to the resuspension of Pu-bearing soil particles to plant surfaces. |
