The radiation safety of the designing constructions in radon-hazardous areas – 2019.

Abstract

The radiation safety of the designing constructions is quite a challenge problem due to the multifactorial nature of the process of forming an internal radon situation. The particular importance is the successful solution of potentially radon-hazardous areas, where the acceptable levels of radon in the indoor air cannot be provided without implementing a set of special radon-protective measures. The article defines the dominant mechanism of radon transportation in soils and walling materials on the basis of their permeability. The recommendations for designing underground walling structures with the required radon-protective characteristics have been proposed. It is shown that radon safety of buildings can be provided on soils with a high natural radionuclides content using exclusively passive radon protection technologies.
