The trouble is nobody – so far – has examined what happens to humans when they are exposed to a lot of Far UVC light. The dead cells effectively protect the living cells underneath. Everything is back to normal. Jon Cartwright reports on a call to arms for the LED industry. Research shows Far UVC light does a very good job of trashing the RNA and DNA inside pathogens like Covid, leaving human skin 'relatively unharmed'. "Unfortunately, conventional germicidal UV light is also a human health hazard and can lead to skin cancer and cataracts, which prevents its use in public spaces. " One even calls it 'stupid'.

COVID-19: how physics is helping the fight against the pandemic. That's because over the past decade or so, we have gradually seen incandescent and fluorescent lighting supplanted by that based on LEDs, which are cheaper, more efficient, more tunable, safer (because they are lower voltage) and longer lasting. In experiments, far-UVC took less than five minutes to reduce the level of indoor airborne bacteria by more than 98 per cent. "[These] also quench light generation and result in very low efficiency. " The new study was conducted by scientists at the University of St. Andrews, University of Dundee, University of Leeds, and Columbia University in New York. In the study, aerosolized H1N1 virus—a common strain of flu virus—was released into a test chamber and exposed to very low doses of 222 nm far UVC light. And then supposing you brought the light inside the body, either through the skin or in some other way.

Far-UVC's wavelength means it can only travel a very short distance in biological material and can't penetrate the layer of dead cells on the surface of our skin, nor the tear layer covering the surface of our eyes. But is it realistic? They conduct meetings in person, and think nothing of it when they jet off to their favourite holiday destination.

Despite LEDs becoming available at shorter and shorter wavelengths – with Nitride Semiconductors in Japan even offering one at 275 nm – most commercially available UV LEDs emit at UVA wavelengths of about 350 nm, where they find applications in the curing of adhesives and ink-jet printing. As a result, it is already in our arsenal against COVID-19 – or more accurately SARS-CoV-2, the novel coronavirus from which the current severe respiratory disease emerges. The UV-FORCE™ is a simple, fast, and safe way to disinfect surfaces, Viruses such as SARS-CoV-2 spread in the air: if that air is irradiated, the viruses find it much harder to reach new hosts. Brenner did not respond to requests from Physics World for an interview. Thanks to Discover Magazine for this story. 99% pathogen kill on surfaces in less than 4 seconds, which is 10 to 1000 times faster than existing UV treatments. However, for the price, you get the only far-UVC lamp on the market that can deactivate viruses and bacteria while not being harmful to humans.

Said Brenner, who is also a professor of environmental health sciences at Columbia's Mailman School of Public Health. DNA is made up of four nitrogen-containing bases, one of which is thymine. Further research will look at its effect on other types of microbes on surfaces in similar sized or even larger rooms. Milk Formula & Baby Food. To do risk assessments, you would probably need to perform experimental tests on animals over a longer time, and also establish, for example, whether hospital gowns provide any protection against this UV light. If LEDs could be mass-manufactured with this sweet-spot in UV emission, explains Ironside, they could be integrated into everyday lighting and consumer technology for pandemic control. However, there is emerging evidence that a narrow range of far-UV wavelengths is safe for humans, while being lethal for viruses. Walk into the gateway and stand with hands up and arms bended at the elbow. USA: +1 754 252 3536.
