Ensuring the Radiation Safety of Construction Projects at the Design Stage

The paper proposes a principally new approach to ensuring the required level of radon safety of construction objects at their design stage. To describe the radon situation in the premises of the lower storey, a mathematical model of two-dimensional stationary diffusive radon transport in the «soil-atmosphere-building» media system was developed. Due to its use, dependences of the radon load on the underground enclosing structures upon the building structural characteristics and the soil block physical properties were obtained. It is shown that in the absence of radiation anomalies, the radon safety of the construction object should be provided exclusively by rational design of the floor structure. An algorithm of the use of this mathematical model at the stage of engineering-ecological surveys for prediction of radon levels in the building after its construction is proposed, its use when realizing the principally new approach to the assessment of the potential radon hazard of the designed buildings is substantiated. This approach does not require the measurement of radon flux density at construction sites.
