Application Of Ultraviolet Type C Radiation To Decontaminate Face Mask

Ultraviolet type C (UVC) radiation have germicidal properties commonly used to disinfect surfaces. Objective of this study was to investigate the effectiveness of UVC radiation for decontamination of surgical mask. Antimicrobial testing using UVC radiation on mask that were inoculated with pathogens were conducted at different exposure time, which were 10, 30, 50, and 60 seconds. Pathogens tested are Acinetobacter baumanii, Bacillus cereus, Enterococcus faecalis, Klebsiella aerogenes, Klebsiella pneumoniae, methicillin-resistant Staphylococcus aureus(MRSA), Pseudomonas aeruginosa, and Influenza A dan B viruses. Exposure of mask toward UVC radiation resulting in 99.9% of reduction in all pathogens tested except P. aeruginosa. This study showed that UVC radiation can be use for decontamination of mask
