A mathematical model is developed for the calculation of air concentrations of material suspended by the wind from areas of surface contamination and the model is applied specifically to the BC Controlled Area. Example computer solutions are given to show the dependence of the suspended air concentration on suspension rate, deposition velocity, wind speed, wind direction and atmospheric stability. This model is subsequently simplified to produce an analytical method for the economical estimation of air concentrations and horizontal fluxes of suspended surface contamination. The predictions of the analytical method are demonstrated to agree quite well with those of the more complex, computerized model.
