Does ultraviolet light kill the coronavirus that causes COVID-19?
TRUE. Specifically, UVC light has been shown to quickly inactivate the novel coronavirus, SARS-CoV-2. It can be an effective disinfectant but needs to be used correctly to avoid damage to the skin and eyes.
Does UVC work on viruses other than the new coronavirus(COVID-19)?
Studies have shown that it can be used against other coronaviruses. One study found at least 15 minutes of UVC exposure inactivated SARS, making it impossible for the virus to replicate.
Can ultraviolet lamps damage the skin?
UVC radiation can cause severe burns (of the skin) and eye injuries (photokeratitis). Avoid direct skin exposure to UVC radiation and never look directly into a UVC light source, even briefly. If customers identify a problem with a UVC lamp, they can report it to the manufacturer and the FDA.
What are the different types of lamps that can produce UVC radiation?
Low-pressure mercury lamp: Historically, the most common type of lamp used to produce UVC radiation was the low-pressure mercury lamp, which has its main (>90%) emission at 254 nm. Other wavelengths are also produced by this type of lamp.
