摘要：
A new procedure is proposed for the investigation of atmospheric radioactivity in the surface air layer through evaluation of specific activity of artificial and natural radionuclides in the aerosol sink. Dry deposition of aerosol particles is described. The collection of aerosol is carried out using a passive sampler in which chemically inert fibrous and powdered materials are used as a sorption substrate. Analysis of experimental results characterizing the features of radionuclide distribution in the aerosol sink during their introduction into a coniferous tree stand is presented.
