title: [The use of impulse plasma-optical ultraviolet technologies for ensuring microbial safety of the space station environment].
abstract: 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. The sanitary-microbiological assessment involved visual and microscopic counting of colony-forming units on material samples (CFU/100 cm2) and Petri dishes after air sampling (CFU/m3 of air). Continuous spectrum of high-intensity pulsed UV was demonstrated to be effective against contamination both by vegetative and high-resistant bacterial spores and molds.
