“…The paper presents experimental data of the radon activity for the period from January 2016 to June 2018. The analysis of time variations was carried out by the method of spectral analysis, which showed the presence of existing natural variations, the mechanisms of which were described by the authors in previous works [12,[19][20][21][22][23][24][25]. The authors measured the activity of natural beta-active radionuclides of radon daughters in the surface layer of the atmosphere.…”

“…In particular, from the inner surfaces of the Earth's crust radon is transported due to the diffusion of aerosols to the surface, to which due to electrostatic attraction the radon atoms coagulate. The authors carried out an areal measurements of soil samples of the surface layer of the earth for the content of betaactive radionuclides of radon daughters [22][23][24][25], taken at different points of the city of Almaty. According to these data, a map of the distribution of the content of beta-active radionuclides of radon daughters in the soil of the surface layer of the earth was constructed.…”

Here we present time variations data of radon emanations in the surface layer of the atmosphere, measured from January 2016 to June 2018. By means of spectral analysis method, we have analyzed time variations and showed the presence of existing natural variations, mechanisms of which were described by the authors in previous works. Authors measured the activity of natural beta-active radionuclides of radon's daughter decay products (DDP) in the surface layer of the atmosphere. The measurements were performed with a beta-spectrometer "Progress" scintillation detector, which is located on the third floor of the Faculty of Physics and Technology at al-Farabi Kazakh National University (KazNU). Measurements of beta spectra were carried out with an exposure of at least for 2000 seconds and during the day up to 10 beta spectra were recorded. The built up time dependence of the integral values of the spectra shows that seasonal variations of natural beta-active radionuclides are manifested on the background of diurnal fluctuations. Thus, 1 day, 4 day, 7 day, 16 day and 30 day variations were found.
