THE CONDITIONS OF DIFFUSIONAL RADON INPUT INTO BUILDINGS AND FACILITIES

Abstract

A lot of investigations have been devoted to the studying of radon entry mechanisms into the buildings. However, there isn't established position to the dominant mechanism of radon transport. The reason of experimental data inconsistency is a significant number of factors influencing the radon input conditions (soil permeability, construction and condition of the construction basement) and wide range of its possible values. In this case the universal model design of the radon input into the buildings is impossible. More promising is the development of a simplified model which adequate to the actual process under certain conditions. This paper defines the conditions for which the description of the process of radon accumulation in rooms of lower floor is possible on the basist of diffusional model.
