Dust resuspension from soil in a semi-arid environment at the Nevada Test Site
Abstract
The resuspension and transport of contaminated dust at an and or semi-arid site create a major source of exposure to people who use the site and to off-site populations. At the Nevada Test Site (NTS), a preliminary base-line risk assessment conducted by the University of Cincinnati indicated that [approximately]90% of the annual effective dose equivalent is derived from inhalation of contaminated dust. Despite the importance of this pathway, very few models exist to predict the resuspension of the soil from the desert pavement. There are no good models to predict the resuspension of soil after soil cleaning or site restoration. There are three types of resuspension processes: 1. wind-related resuspension/suspension; (2) mechanical resuspension/suspension; and (3) local resuspension or suspension. Mechanical and local resuspension originate from mechanical disturbance of the soil. This paper discusses the analysis of wind-related resuspension based on physical principles and examines revegetation or mulching of the cleansed soil.
