29-10-2011 Soms vragen onze klanten ons wat het wetenschappelijke bewijs is voor de desinfecterende werking van UVC licht. Naast natuurlijk de praktijkervaring die we hebben opgedaan kunnen we de effectiviteit van UVC als technologie onderbouwen met talloze onderzoeken, hieronder een aantal citaten. (Engels) “Levels of fungi growing on insulation within air-handling units (AHUs) in an office building and levels of airborne fungi within AHUs were measured before the use of germicidal UV light and again after 4 months of operation. The fungal levels following UV operation were significantly lower than the levels in control AHUs.” Uit: Effectiveness of Germicidal UV Radiation for Reducing Fungal Contamination within Air-Handling Units Estelle Levetin, Richard Shaughnessy Christine A. Rogers and Robert Scheir. Faculty of Biological Science and Department of Chemical Engineering, The University of Tulsa, Tulsa, Oklahoma. “Operation of UVGI resulted in 99% (95% CI 67-100) reduction of microbial and endotoxin concentrations on irradiated surfaces within the ventilation systems.”.. “UVGI may be a cost-effective method of alleviating work-related symptoms caused by microbial contamination of office ventilation systems.” Uit: Menzies D, Popa J, Hanley JA et al. Effect of ultraviolet germicidal lights installed in office ventilation systems on workers’ health and wellbeing: double-blind multiple crossover trial. Lancet 2003; 362: 1785–1791.
“UV light, which continues to be a reliable means of disinfection, involves exposing contaminated water to radiation from UV light. The treatment works because UV light penetrates an organism’s cell walls and disrupts the cell’s genetic material, making reproduction impossible.”
