PROTECTION OF THE AIR ENVIRONMENT OF RESIDENTIAL AND PUBLIC BUILDINGS FROM RADON

Abstract

Statement of the problem. Most individual annual radiation dose in buildings is received from the radioactive gas radon and its progeny. However, the problem of ensuring the indoor air radiation safety is still far from being resolved due to the lack of an established viewpoint on the process of radiation situation formation, which is partly due to the insufficient development of the theoretical base in the field of radon protection of buildings.Results. The base of investigations is the method of analogies implemented within the framework of an interdisciplinary approach. The general features of the processes of heat and mass transport through external walling are noted, the correspondence of thermal physical and radiation values is identified, the characteristics with a clear physical value (radon resistance and radon permeability) are introduced. In the future, they can be used to quantitatively assess the radon protective ability of building materials and the floor constructions. Conclusion. The study results allow one to conclude that the use of means and methods of thermal physics is promising for ensuring acceptable radon levels in buildings. The results make it possible to expand the conceptual apparatus of radon safety and open up opportunities for the development of a theoretically grounded concept for the design of radon-safe buildings.
