Abstract: The influence of atmospheric and soil radon on the state and dynamics of atmospheric fields of alpha, beta and gamma radiations. Atmospheric radon (its isotopes and daughter decay products) affects the atmospheric ionizing radiation field and is a source of "variable" component of radiation fields. According to popular belief, soil radionuclides are the source of "permanent" component of the atmospheric radiation fields. Analysis of the modeling results of transport of ionizing radiation, formed by atmospheric radon and soil radionuclides, under radioactive equilibrium in the natural uranium and thorium series, showed that: 1) atmospheric gamma-ray background are formed mainly by soil radionuclides, the contribution of atmospheric radon is, on average, 0.1%; and 2) under certain meteorological conditions the contribution of atmospheric radon in the gamma-ray background can reach 10% only at altitudes of up to 1 m; 3) atmospheric radon noticeable impact on the beta radiation field of surface atmosphere, and the contributions of atmospheric radon and soil radionuclides comparable and their ratio is highly dependent on weather conditions and height above the earth's surface. Calculations are show that the change in humidity, when other factors are being equal of the environment, it gives a considerable contribution to the changing of the dose of gamma and beta radiation, and in the fluxes of gamma and beta radiation. Influence of soil radon to the atmospheric radiation field are discussed in detail in the report.
