   The paper considers the results of expedition measurements of atmosphere
   electrical characteristics and radon-222 concentration in soil gas and
   near ground air at Rostov region and Mt. Elbrus highland sites.

   The data, obtained during a series of expeditions, are analyzed together
   with meteorological characteristics of the lower atmosphere to determine
   the role of radon-222 in the processes of formation of the near ground
   atmosphere electric structure.

   Correlation of radon content in the atmospheric air with temperature
   conditions of the upper 20-cantimeter soil layer, influencing radon
   exhalation, is demonstrated.

   According to the results of measurements there is a close correlation
   between atmosphere electric conductivity and radon-222 concentration in
   the atmospheric air. Regression equations of polar electric conductivities
   on radon concentration in the atmosphere are calculated.

   Analysis of vertical profiles of atmosphere polar electric conductivities
   and the electric potential gradient in the lower 3-meter layer,
   considering the conditions of stability in the atmosphere and radon-222
   content, allow us to propose a physically based interpretation of a system
   of atmospheric and electrical regularities observed near the ground.
