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.

Measurements of the spatial distribution of radon isotopes were carried out from April 2021 to August 2021 in the foothills of the Trans-Ili Alatau of the Tien Shan in the Almaty region at various heights above sea level: from 500 to 2500 meters. They were carried out using electronic radiometric equipment: beta-dosimeter “RKS-01B-SOLO”; gamma dosimeter “RKS-01G-SOLO”; radiometer of radon and its daughter decay products “RAMON- 02” in the field. As a result, preliminary assessment schemes were built for route measurements of the 222Rn radon isotope, beta and gamma radiation fields from natural daughter products of decay of radon isotopes and radionuclides located in the surface atmospheric layer.
