Summary
We propose a theoretical model based on the eddy diffusion which elucidates the polar conductivities repartition near the ground and the conductions current variations in relation with the altitude in the exchange layer. Investigations concerning the theoretical repartition of the electrical field and the space charge in relationwith the altitude were carried out and a method for calculating the diffusivity from electric parameters values (electric field, space charge, conductivity) near the ground surface has been elaborated. The diffusivity values thus obtained are compared with those deduced from the measurements of the thoron concentrations at different levels carried out on the same spot as the electric parameters measurements and at the same time.
