you can reposition and redeploy the device. Others measure light
reflected back to the device, but this isn't truly representative of the
dose delivered throughout a space, as different surfaces reflect light
to varying degrees. In Europe, you can place disposable dosimeters
anywhere throughout a room to document the dose achieved in those
locations.
This delivered-dose measurement is critical. Research has shown
that UV-C disinfection is limited by the distance between the light
source and the targeted surface — especially in shadowed areas or
areas not in the direct line of light — and in the presence of organic
matter.
A final concern: Repeated exposure to mercury-based UV-C light
can result in degradation of some plastics and polymers.
• Hydrogen peroxide vapors or aerosols. Perhaps the greatest
strength of hydrogen peroxide vapors or mists is their biocidal action.
They effectively eliminate bacteria — including MRSA,
Mycobacterium tuberculosis, vancomycin-resistant enterococci and
multidrug-resistant Acinetobacter spp. — as well as viruses, fungi and

Just as important as handwashing, manual cleaning
and antibiotic stewardship are to preventing hospital
infections, so is disinfecting the room from top to
bottom. Tru-D's unique, programmatic approach to UVC
disinfection and commitment to excellent customer
experiences, results in substantial cost savings and
improved patient outcomes, hospital-wide.
