What are the different modalities
of UV surface treatment? How
are these modalities alike and
how do they differ?
The primary difference between
continuous UV lamps and pulsed
xenon devices is the chemistry
used to generate the ultraviolet
light. Pulsed xenon technology
uses xenon gas to generate a
broad spectrum of light, of which
only a fraction is in the germicidal
range. Continuous low-pressure
mercury UV lamps are analogous
to fluorescent lamps that are used
in commercial buildings all over the
world, except instead of glass they
are made of quartz to allow germi-

cidal UV to pass through.
What are the most compelling
findings from recent clinical research surrounding UV technology and HAI/SSI reduction?
Researchers from the University
of North Carolina recently found
that UV-C technology effectively
reduces environmental contamination in patient rooms and should
be considered when environmental
transmission is significant (e.g.,
after discharge of patients under
contact precautions). The study
results showed that a UV-C device
achieved a total 3.56 log10 reduction for MRSA in five minutes and
a total 2.78 log10 reduction for C.
difficile spores in 10 minutes.
Additionally, in a recent study

over a 12 month period. The vast

oncology floors were being treated
for blood cancers, including leuke-
mia and multiple myeloma and were
