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