ULTRAVIOLET LIGHT AS DISINFECTANT

“ULTRAVIOLET LIGHT HAS A LONG HISTORY AS A DISINFECTANT AND THE SARS-COV-2 VIRUS, which causes Covid-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight the spread of the virus and protect human health as people work, study, and shop indoors.” https://www.inverse.com/science/ultraviolet-light-can-make-indoor-spaces-safer-during-the-pandemic

UV-C and SARS CoV-2

Researchers in Italy have found that it is possible to completely inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using short-wavelength UV (UV-C) irradiation. https://www.news-medical.net/news/20200608/Irradiation-with-UV-light-kills-SARS-CoV-2.aspx

UV-C and SARS CoV-2

Signify today announced that Boston University has determined that a Signify ultraviolet (UV) light source would almost always deactivate the coronavirus that causes COVID-19 if dosed at the right level. The university’s National Emerging Infectious Diseases Laboratories (NEIDL) exposed materials containing the virus to a UV-C tube lamp from Signify. It found that a dose

About LED UV-C

“On LED at 254 nm, as of now, we see that the power that comes out is still not adequate,” Chitale told LEDs. While Signify is not ruling out LED in the long run at 254 nm, its current LED disinfection products tend to be in the UV-A band. Last week, Rondolat noted that at 254

Ultraviolet (UV) light is a commonly used method for killing bacteria, but could it help with disinfecting areas contaminated with COVID-19? A breakthrough discovery of a new class of transparent conductors could be the answer.

Two UV infection control methods of killing bacteria currently exist, which use chemicals or ultraviolet radiation exposure as a form of disinfectant, using a 200 to 300 nanometre range. However, in order to kill the COVID-19 virus very high levels of ultraviolet light is required, which can be very costly. Now, researchers from Penn State and the University of Minnesota have used the
