Chapter 1 Introduction The objective of the present report is the evaluation of modeling techniques for atmo- spheric dispersion of particulate matter at diFerent DOE Sites. There is a main concern for potential human health risk from toxic and radioactive material release into the at- mosphere from diFerent DOE Sites. Particulate matter release into the atmosphere is an important pathway for potential radioactive dose to human receptors onsite and oFsite of DOE Sites. Particulate matter releases are due to direct emissions into the atmosphere and due to secondary vapor to particulate formation. DiFerent mechanisms for particulate dispersion and transport have been evaluated in the present report, as the mechanisms of dry and wet deposition, estimation of dispersion parameters, treatment of pollution sources, condensation and nucleation processes, and resuspension from soil. An atmo- spheric turbulence spectra method has been proposed for the estimation of dispersion parameters and a Green’s function formulation for the derivation of the Gaussian Plume equation as a solution of the atmospheric diFusion equation. In addition resuspension due to atmospheric turbulence and surface vibrations is examined as possible pathways for particle resuspension from diFerent surfaces. Two diFerent resuspension models have been
