ABSTRACT = {Convection and diffusion are the main factors affecting radon migration. In this paper, a coupled diffusion-convection radon migration model is presented taking into account turbulence effects. In particular, the migration of radon
is simulated in the framework of the <i>k-ε</i> turbulence model. The model equations
are solved in a complex 3D domain by the finite element method (FEM). Special
attention is paid to the case study about radon migration in an abandoned air
defense shelter (AADS). The results show that air convection in a confined space
has a great influence on the radon migration and the radon concentration is inversely proportional to the wind speed.},
