The dose from radon and its progeny is a controlled component of the radiation load
on the population, and therefore can be reduced by the use of appropriate construction
technologies. The article shows that the convective flow can be reduced to zero by choosing
the appropriate floor construction, whereas the diffusion cannot be completely excluded, and
the diffusion radon flux can only be reduced to a certain level. An approach to the assessment
of the required radon-protective characteristics of the building is proposed under the
assumption that there is no convective radon entry. As a radon load on the underground part of
the building, the radon potential of the soil, determined by the results of gamma-spectrometric
analysis of the soil from the construction site, was used. The procedure for calculating the
geometric characteristics of layers with high resistance to radon permeability based on the
required radon concentration in the ground floor premises of the building after its construction
and the radiation characteristics of the soil on the construction site is shown.
