In the article the authors present the data of periodic variations in time of radon emanations in the ground layerof the atmosphere, which were measured for the period from January 1 to August 3, 2016. Harmonics ofdiurnal, 4-day and longer periods are revealed. The authors interpreted the 4-day variations, which can occurdue to "lunar tides", that is, from soil uplifts due to the increase in gravitational tidal forces. The mechanism ofradon emanation to the Earth's surface is complex. The mechanism of radon emanation to the Earth's surface iscomplex. In particular, the transportation of radon from the inner surfaces of the earth's crust is carried out bythe diffusion of aerosols onto the surface, to which the radon atoms coagulate, due to electrostatic attraction.Such radioactive aerosol nanoparticles located in the surface layer of the atmosphere have the greatest impacton the risks of cancer, since the probabilities of their settling on the lung tissues are several orders of magnitudehigher than the radon itself in the atomic form.
