ENSURING THE RADIATION-ECOLOGICAL SAFETY OF CONSTRUCTIONS

Abstract

Now the radon flux density from soil surface is the only criterion for the radon hazard of construction site. However, the radon flux density determination at the environmental surveys stage does not provide initial data for the design of buildings radon protection. In such conditions, a fundamentally new methodology is needed to ensure the buildings radon safety at the design stage, which based on the unified media system “soil-atmosphere-building” consideration. The paper proposes an approach to determining the required radon-protective properties of a building on the basis of an analysis the soil characteristics and building underground part construction. This approach not only takes into account the construction site radiation and geological characteristic, but also allows the selection of optimal design solutions for underground walling. Its use will reduce the cost of engineering and environmental research and avoid the buildings with excess or insufficient radon-protective properties commissioning.
