In this paper, we have developed a method that allows us to evaluate the radiation activity of radon-222 based on mathematical modeling in the design of residential buildings in accordance with the rules for designing anti-radon protection. The method is based on the numerical solution of the diffusion, heat transfer, and Navier - Stokes equations, supplemented by appropriate turbulence models, initial and boundary conditions, in particular, the process of natural decay and sedimentation of radon-222 in the room is taken into account. Verification of the method for residential premises of an apartment building located on the territory of Saint Petersburg was performed. Using the proposed calculation method allows you to identify the most radiation “dangerous” places in the room, rationally organize the air exchange and configuration of the room, prevent the development of “sick building syndrome”, etc.
