title: [The study of biocide effectiveness of ultraviolet treatment in media stimulating space station environment].
abstract: An experiment was performed to study the biocide effect of ultraviolet treatment of simulated space station milieu. UV generated by low and moderately power-intensive sources (from 10 W to 1 kW) showed a good promise for decontaminating, within the reach, solid structural materials, and the air and water in the cabin. For instance, within 10 minutes of the UV-treatment aerial bacteria in 20 m3 were reduced in 12 to 30 times while fungal microflora was fully suppressed. Water containing spores and vegetative cells of both pathogenic and nonpathogenic microorganisms became essentially sterile after 4 to 10 minutes of treatment with low UV (in the order of 0.01 W/cm2). Different UV modalities can lay the basis for development of specific technologies of microbial decontamination of various spacecraft.
