How do I determine which fixture or wattage is best for my application?
Click these links to spec sheets to determine irradiation rates per room size: 5′ UV Tower vs 6′ UV Tower. Higher wattages and UV outputs and will take less time to disinfect a given area. Dosage charts are also listed on page 2 of each specification sheet.
What is germicidal UV, and what is UVGI?
Germicidal UV (GUV) refers to using ultraviolet radiant energy to inactivate bacteria, mold spores, fungi, or viruses. When the process is applied in a given location, it has generally been referred to as ultraviolet germicidal irradiation (UVGI). Because of the public’s concern about ionizing radiation (e.g., X-rays and gamma rays), the term GUV avoids needless concerns about a link with that type of radiation. Another non-technical term is germicidal light, although “light” is technically only visible radiation.
Is all ultraviolet considered germicidal ultraviolet (GUV)?
No. Germicidal ultraviolet (GUV) – refers to short-wavelength ultraviolet “light” (radiant energy) that has been shown to kill bacteria and spores and to inactivate viruses. Wavelengths in the photo-biological ultraviolet spectral band known as the “UV-C,” from 200 to 280 nanometers (nm), have been shown to be the most effective for disinfection, although longer, less energetic UV can also disinfect if applied in much greater doses. UV-C wavelengths comprise photons (particles of light) that are the most energetic in the optical spectrum (comprising UV, visible, and infrared) and therefore are the most photochemically active.
Can UV-C kill viruses as well as bacteria?
Yes, UV-C kills living bacteria, but viruses are technically not living organisms; thus, we should correctly say “inactivate viruses.” Individual, energetic UV-C photons photochemically interact with the RNA and DNA molecules in a virus or bacterium to render these microbes non-infectious. This all happens on the microscopic level. Viruses are less than one micrometer (µm, one-millionth of a meter) in size, and bacteria are typically 0.5 to 5 µm.
Can UV-C effectively inactivate the SARS-CoV-2 virus, responsible for COVID-19?
Yes, if the virus is directly illuminated by UV-C at the effective dose level. UV-C can play an effective role with other methods of disinfection, but it is essential that individuals be protected to prevent UV hazards to the eyes and skin.
Does the ultraviolet in sunlight have a GUV effect?
Yes, particularly in the late spring and early summer when the sun is high in the sky and the UV index is high. At a UV Index of 10, the duration to achieve at least a three-log kill of bacteria (99.9% killed) is estimated as less than one hour.
How effective are portable UV towers for surface disinfection?
Portable UV germicidal towers and robots have been used to move around a room to disinfect surfaces with UV-C in all directions. The UV-C radiant energy is normally emitted by long, vertical mercury lamps or pulsed xenon lamps. Very intense emission can cover much of the room in a relatively short time. Further, by moving autonomously around the unoccupied workspace it can expose surfaces that would not be easily reached by fixed GUV lamp installations. If good air movement is present, most air will be disinfected as well. Surfaces with a thick buildup of residues may pre-absorb the UV-C photons before they reach the active virus or bacterium. As with all GUV systems, they should be considered as an effective adjunct to standard infection control cleaning guidance. These mobile units should be used after terminal cleaning.
What types of lamp sources are used for UV Germicidal disinfection?
Lamp technologies include continuously emitting low- and medium-pressure mercury lamps, as well as pulsed xenon arc lamps. Studies have shown that these technologies—continuously emitting or pulsed—are comparably effective for disinfection. Light-emitting diodes (LEDs) and krypton-chlorine excimer lamps, which emit in narrow bands in the germicidal range (UV-C), are emerging technologies but have not been developed as an effective lamp source.
What is currently the most widely used lamp source of UV-C for GUV?
The most practical method of generating germicidal radiant energy is by the passage of an electric discharge through a rare gas (usually argon) at low pressures (on the order of 130 to 400 pascals, or 1 to 3 torr) containing mercury vapor enclosed in a special glass tube with no coating that transmits short-wavelength UV. Hot-cathode germicidal lamps are identical in shape, electrical connection, operating power, and life to standard fluorescent lamps, both linear and compact types. Maintaining the transmission of the lamp over life is more difficult than for standard fluorescent lamps. Cold-cathode germicidal lamps are also available in various sizes, usually for shorter, smaller diameter lamps. Their operating characteristics are similar to those of hot-cathode lamps, but their starting mechanisms are different.
How do research scientists determine efficacy for killing or deactivation of different microorganisms and viruses?
The most fundamental concept in photobiology is the action spectrum (or relative response) for a given effect. Although there is a standardized germicidal action spectrum in the IES Handbook, it was based on the inactivation of E. coli bacteria, and action spectra for spores, other bacteria, and different viruses can vary. This standardized action spectrum extends from 235 nm to 313 nm and peaks at approximately 265 nm. A wavelength of 254 nm has a relative efficacy of 0.85; by contrast, 313 nm in the UV-B has a relative efficacy of only 0.01.
Germicidal effectiveness is proportional to the exposure dose (radiant exposure, typically in millijoules* per square centimeter, mJ/cm2, or joules per square meter, J/m2 ), which is the product of the dose-rate (irradiance, typically in mW/cm2 or W/m2 ) and time (from 1 μs to several hours). A nonlinear relationship exists between UV exposure and germicidal efficacy. For example, if a certain UV exposure kills 90% of a bacterial population (frequently referred to as “one-log kill”), doubling the exposure time or intensity can kill only 90% of the residual 10%, for an overall germicidal efficacy of 99% (“two-log kill”). Likewise, a 50% decrease in dose or exposure time decreases germicidal efficacy only from 99% to 90%.
