Abstract
This report develops a mathematical basis for using simple site measurements to estimate soil radon potential. The approach utilizes a lumped-parameter model of radon generation and entry that was developed previously for Florida house and soils from the more detailed RAETAD numerical mode. Site-specific soil radon potential is defined as the rate of randon entry into a reference house, consistent with the definition used previously for the radon potential maps. The models show that, in the simplest case, soil radon potential can be reduced to a simple function of two measurable parameters: the soil surface radon potential can be reduced to a simple function of two measurable parameters: the soil surface radon flux and the soil moisture (as a fraction of saturation). The flux gives the radon generation rate of the soil profile, and the moisture is a surrogate for random transport parameters, including air permeability and random diffusion coefficient. For comparison to indoor randon levels, the randon flux can also be related to sub-slab random concentrations. Measurements of randon flux from concrete floor slabs also can be used to estimate the non-advective contribution to radon entry rates.
