Abstract The report describes the theoretical basis, implementation, and validation of the RAdon Emanation and TRAnsport into Dwellings (RAETRAD) model, a conceptual and mathematical approach for simulating radon (222Rn) gas generation and transport from soils and building foundations to the indoor environment. It has been implemented in a computer code of the same name to provide a relatively simple, inexpensive means of estimating indoor radon entry rates and concentrations. RAETRAD uses the complete, multi-phase differential equations to calculate radon generation, decay, and transport by both diffusion and advection (with pressure-driven air flow). The equations are implemented in a steady-state, 2-dimensional finite-difference mode with elliptical-cylindrical geometry for maximum efficiency and modeling detail. The radon generation, decay, and transport part of RAETRAD was validated by similar comparisons with 1-dimensional analytical calculations for open and concrete-covered soils. Most radon concentration profiles and surface radon fluxes for these comparisons were also within 1%.
