Limitation of Radon Inflow from the Soil into the Building due to Construction Technologies

Radon and its progenies form a large part of the annual individual radiation dose of the population in countries with a temperate climate, at this practically almost all radon enters the building from the soil at its base. Modern construction technologies make it possible to ensure the radon safety of residential and public buildings according to the soils with different radium contents. However, the laws of radon transfer in the soil and construction materials are not fully understood now. Therefore there are no reliable methods for the design calculation of radon-protective ability of the underground enclosing structures. As a result, the buildings with excessive or insufficient radon-protection characteristics take into exploitation, which leads to an unjustified increase in costs for construction and reconstruction. The paper proposes an approach to ensuring acceptable radon levels in rooms based on determining the required resistance of horizontal underground enclosing structures to radon penetration according to the physical and mechanical characteristics of the soil on the planned construction site.
