2. What Is Ultraviolet Light?
UV-A (315nm - 400nm)
Black lights and tanning lamps,
harmful to eyes
UV-B (280nm - 315nm)
Causes sunburn and skin cancer
UV-C (200nm - 280nm)
Germicidal - Damages DNA in
cells, optimum at 254 nm
-Shorter wavelength
-Higher energy
5. UVC Efficacy
Level of disinfection is measured in terms of % disinfection
or log reduction
Log 1 (90%) Log 2 (99%) Log 3 (99.9%) Log 4 (99.99%)
Log reduction achieved on a target micro-organism is a
function of applied UVC dose
Total Applied Dosage = UVC intensity at target x Time
Total intensity output of UVC device factors
Lamps Configuration & Lamp Output
Height of lamps/device
Other design aspects such as reflective components
6. UVC Efficacy
UVC Dose to achieve a specific log reduction varies from
one micro-organism to another
Acinetobacter Baumannii
6,600 µW-sec/cm2
Influenza A
4.558 µW-sec/cm2
Clostridium difficile
38,500 µW-sec/cm2
MRSA
7,106 µW-sec/cm2
VRE
12,600 µW-sec/cm2
Aspergillus Niger
330,000 µW-sec/cm2
UVC Dose Values for 99% Disinfection (2 Log Reduction)
7. Time to disinfect a room is dependent on the organism,
disinfection level and distance from UVC device
D99% (2 Log) Disinfection Time (Min) at Distance (Ft)
Microorganism 3 ft. 8 ft. 12 ft.
