A mathematical model was developed to estimate the dispersion and deposition of a contaminated flow. The model, which is independent of the nature of the contaminate source, is based on an analogy between the kinetic theory of gases and real turbulent flows. The average contamination concentration and deposition rate to the flow boundary as a function of the distance downwind of a reference point are given by calculations based on the model. Assumptions and limitations of the model and their significance are discussed. The results of calculations using the model are qualitatively supported by available experimental data. The model is applicable to radioactive and nonradioactive air pollutants.
