title: Three-dimensional treatment of steady-state 222Rn diffusion in building materials: introducing a practical modified one-dimensional approach.
abstract: A three dimensional solution of the steady state diffusion equation, with boundary conditions applicable to closed can 222Rn exhalation measurements is described. A modified one-dimensional formalism is introduced which allows the interpretation of the results from exhalation measurements in terms of one-dimensional 222Rn exhalation from walls.
