FIELD: environment protection.
SUBSTANCE: invention relates to field of environment protection and is intended for catching dry aerosols in case of detecting aerotechnological surface contamination. Method of catching dry aerosols includes precipitation of dry aerosols on depositing substrate. As substrate chemically inert finely dispersive powder which possesses good surface wettability is used. Before precipitation, gradient of temperatures between substrate and atmospheric air flow is created. Aerosol precipitation on substrate is performed by turbulent diffusion of aerosol particles into substrate from border layer, formed when turbulent and convective flows move above the substrate and by catching precipitated particles by means of capillary condensation.
EFFECT: increase of quality of aerosol particles collecting and reliability.
