UV Irradiation Dosage Table
The following are incident energies of germicidal ultraviolet radiation at 253.7 nanometers wavelength necessary to inhibit colony formation in microorganisms (90%) and for 2-log reduction (99%):
VIOTECHE –Lights lamp produces 4,400 µW/cm² @ 2'
UV dose = UV intensity x time in seconds.To compute time needed to inactivate germs in the following chart at 2' distance divide the UV dose by 4,400.
Example:
for 99% kill factor of Infectious Hepatitis: 8,000 divided by 4,400 = 1.8 seconds.

The list of viruses was compiled according to a corresponding list published by the Robert Koch Institute in cooperation with the German Association for the Control of Virus Diseases and the German Society for Hygiene and Microbiology (RKI, DVV, DGHM 2004), according to the U.S. Departments of Health and Human Services (CDC 2004) and Büchen-Osmond 2003a, b). The predicted values for UVC sensitivity were adopted from Lytle & Sagripanti (2005).
