| Abstract |
The objective of this research was to study the factors that relate to the effectiveness of upper-room ultraviolet germicidal irradiation for inactivating airborne microorganisms. The work was conducted in a laboratory chamber designed and furnished to simulate a hospital room. Nebulized Serratia marcescens, Bacillus subtilis spores and vaccinia virus were used as test aerosols. Data were collected from steady-state experiments comparing the number of viable organisms in the chamber air remaining with UV lamps turned on to the number with UV lamps turned off. UV power level had a strong influence but was fully effective only in the presence of strong air mixing. In conclusion, an ultraviolet installation is a complex system that requires careful integration of UV luminaries, UV power and room ventilation systems. See also CIS 09-000, ISN 6. |
