The decontamination cover includes a sheet-like body formed from a pliable material, and includes an outward-facing surface that is substantially opaque to UVC light and an inward-facing surface that is to be arranged opposite a surface of the object to be decontaminated. A plurality of UVC sources are exposed at the inward-facing surface, and a plurality of spacers are arranged among the UVC sources to maintain a suitable separation between the UVC sources and the surface of the object to be decontaminated. This suitable separation promotes complete coverage of the surface with UVC light emitted by the UVC sources.
Thu, 03 Nov 2016 08:00:00 EDTSolutions for limiting the undesirable spread of pathogens by indirect contact are provided. The solutions involve heat-sanitization of contact regions on articles or fixtures by flowing selected electromagnetic radiation energy through underlying waveguide structures substantially parallel to the contact regions.
