A new method for estimating the coefficients of diffusion and emanation of radon in the soil

This paper describes a new method for determining the basic parameters of soil - diffusion and emanation coefficients related to the transfer of radon in the soil matrix, which are very useful for testing models, based on diffusion and characteristics of various soil matrices regarding the dangers of radon. The method is based on the measurement of radon in soil air on two small depths, differing twice. The paper presents the results of the determination of the parameters for covering loams and clays of Tomsk (Russian Federation), obtained by this method. - Highlights: • This paper describes a method for determining diffusion and emanation coefficients. • The method is based on the measurement of radon in soil air on two small depths. • The paper presents the results for the parameters for covering loams and clays
