ABSTRACT

Experimental determination of diffusion parameters in the upper part of geological section (presented by clayey weathering crust) was made by a point instantaneous source method in a diffusion mode and a linear instantaneous source diffusion-advective mode. The results obtained by these methods showed a fairly good coincidence of the obtained diffusion characteristics of the medium. The time to determine the diffusion characteristics of the medium is significantly reduced by more than an order of magnitude when using the advective method. This is a prerequisite for the widespread use of methods for determining radon hazard based on measurements of the vertical distribution of radon volume activity in the upper part of the geological section.
