[The use of impulse plasma-optical ultraviolet technologies for ensuring microbial safety of the space station environment].

Purpose of the work was to study usability and efficiency of UV decontamination units aboard space station. UV-radiators were high-intensity xenon flashbulbs, as well as standard mercury and amalgam lamps; subjects were reference strains and test-microorganisms isolated from the ISS environment. Quantities of viable airborne and superficial microorganisms were determined before and after UV irradiation.
