Elucidation of the character of radionuclide concentration changes in the near ground layer of air

The Fokker Planck equation was used to analyze the probability of the appearance of radionuclide impulses of any type. Distribution functions for the stationary state and conditions when different factors influence the impulse amplitude and duration are presented. A high degree of correlation was obtained between our results and an analysis of distribution functions of radioactivity and seismic noises in certain regions in Europe and Japan found in the literature. This presents a contribution to the further explanation of the mechanism of radioactivity changes in the near ground layers of air.
