UVC LIGHT FAQ

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UVC) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.

It is unlikely that UVC from artificial sources presents an acute or long-term hazard to human skin. ... UVC exposure is unlikely to cause acute or long-term damage to the skin but can cause severe acute damage to the eye and should not be permitted at all from any tanning device.”

UVC radiation refers to wavelengths shorter than 280 nm. These wavelengths are entirely absorbed by our atmosphere and no natural UVC radiation reaches the surface of the earth. These wavelengths are available to us through artificial sources, such as UVC mercury lamps. The intensity from point sources like UVC LAMPs falls off as 1 over distance squared, and once it gets past the scattering length, it falls off exponentially. This means that 1) the further away the UVC source from a human, the lesser dose he is exposed to, and 2) the absorption length of UVC radiation in human skin is extremely short so that almost no UVC radiation can reach the living cells in the skin; all the absorption occurs in the dead cell layers.

UV-C's effects on the human body vary depending on length of exposure, but can cause painful burns on the skin. It can also cause temporary damage to the cornea if observed directly. Aside from these threats, UV-C is a known carcinogen for human skin.

To my knowledge, UVC radiation has not been shown to be a cause of human skin cancer or other types of human cancer, although some experiments with mice have demonstrated a causative link between squamous cell cancer and UVC irradiation.

Ultraviolet radiation is produced by high-temperature surfaces, such as the Sun, in a continuous spectrum and by atomic excitation in a gaseous discharge tube as a discrete spectrum of wavelengths.

UV-C light is germicidal – i.e., it deactivates the DNA of bacteria, virus and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA.

UV sterilization also known as UV disinfection or ultraviolet germicidal irradiation (UVGI) works by breaking down certain chemical bonds and scrambling the structure of DNA, RNA and proteins, causing a microorganism to be unable to multiply.

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.

A germicidal lamp is an electric light that produces Ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoa. It can also be used to produce ozone for water disinfection.

There hasn’t been any research looking at how UVC affects Covid-19 specifically, studies have shown that it can be used against other coronaviruses, such as Sars. The radiation warps the structure of their genetic material and prevents the viral particles from making more copies of themselves.

In simple terms, when bacteria or another type of microbe is directly exposed to certain types of UV light, the DNA (its fundamental building block) of the cell is damaged, preventing it from replicating. If a cell cannot reproduce, then the cell cannot cause infection, which is how UV light kills bacteria.

Yes, UVC light can kill mold.

Unfortunately, not all mold spores will be eliminated by surface cleaning. In these cases, ultra-violet (UV) lamps are effective in killing mold and mold spores. UV-C lamps, which provide UV light on the C-bandwidth) are best for dealing with mold problems, as other types of UV light don't damage the mold enough.

In fact, UV-C is so effective at killing pathogens that it is already used in hospitals to disinfect air, surfaces, and water. You can buy a device for personal use, such as the GermGuardian UV-C sanitizing light wand (www.germguardian.com) to wave over your feet and kill fungal pathogens.

ICREOS is completely safe for your phone. ICREOS doesn't use water or chemicals – it uses UV-C light. UV light kills germs but doesn't harm you or your device. This light is completely safe for anything you place inside – except germs.

Its UV light is completely safe for your gadgets. UV light can potentially cause damage with continuous, prolonged exposure to plastic. However, it would take many continuous hours of exposure to have this effect. When you use ICREOS to sanitize, the UVC lights will turn on for 1/5/15 minutes (ICREOS designs 3 Modes for your selection) and automatically shut off when done. This is more than enough time to completely sanitize your phone and kill all the germs, but it is never enough time to damage your gadgets. You can feel confident your phone is safe inside, but the germs are not!

UVC light cannot pass through glass. There is no harm to look through an air handling unit access window at UVC lighting.

When produced by the sun, UV-C does not penetrate the earth's atmosphere. Standard window glass, according to the International Ultraviolet Association, will allow UV-A to pass through while almost 100% of the UV-B and UV-C light is blocked.

No. UVC light can not detect germs. UVA light can.

Also known as long-wave ultraviolet light (or UVA light), blacklight causes specific materials to "fluoresce" or radiate visible light in total darkness. ... Since certain bodily fluids can transmit certain sickness-causing bacteria and viruses, a blacklight can also help you detect potentially threatening bodily fluids.
