Find UV Light facts, including action on microorganisms, dosage tables, safety and definitions
Germicidal ultraviolet light inactivates microorganisms by disrupting their cellular membranes and by damaging their DNA or RNA.
UV light will kill any DNA-based microorganism given enough UV dosage.
Safety of Upper-Room Ultraviolet Germicidal Air Disinfection for Room Occupants
UV abbreviations and definitions - the most common UV terminology used in association with UV and germicidal UV technology systems
The effectiveness of any UV application depends on delivering a sufficient UV dose to inactivate the target microorganisms.In air and surface disinfection the UV dose is calculated as follows:
UV dose* = UV intensity x Exposure time
An applications engineer knows how to take under consideration all the variables which affect the UV dose.

* The UV dose is usually expressed in microwatt-seconds per square centimeter (µWs/cm²) or milli-Joules per square centimeter (mJ/cm²).
