Radon transport from the subsurface: The roles of certain boundary conditions at subsurface/environment boundaries

Year: 1990

Type: conference-paper

Abstract: The effects of wind on radon transport from its soil source to the environment are examined in two situations. In the first situation, the removal of radon from the soil-air interface was found to be partially rate limiting in conditions of nearly stagnant air (low wind). This gas-phase mass transfer limitation became especially important when high exhaling advective velocities or high diffusion fluxes to the air existed. A detailed mathematical formulation for one-dimensional steady-state radon transport from the soil to the air using an air side mass transfer coefficient was developed for this analysis. In the second situation, the Rn3D computer code was used to estimate radon concentration profiles in soils beneath a two-dimensional slab-on-grade dwelling subjected to wind pressures. Of five generic dry homogeneous soils studied (gravel, sand, silt, loam and clay), only gravel showed significant changes in subslab concentrations as a results of wind pressures. 7 refs., 6 figs., 4 tabs.
