A sizable reduction of the indoor radon progeny exposure level is anticipated in structures from the application of a radon barrier to the indoor surfaces of concrete foundations, behind or in which uranium mill tailings exist. The predicted accumulation of radon and gamma emitting radon progeny behind the barrier was studied. Radon accumulations were modeled by application of linear diffusion theory to a multilayered system of porous media. A comparison of the gamma exposures associated with concentration profiles prior to and after application of a radon barrier resulted in the prediction of sufficiently low fractional increases to justify field testing of the barrier.
