With the proper use of an optical filter to eliminate harmful UV wavelengths, this study confirmed that filtered 222nm Far-UVC light is safe for humans and does not induce skin damage.Ī Eadie et al case study also confirmed the criticality of an optical filter to ensure 222nm-Far-UVC safety by tests on human skin. Far-UVC light (222 nm) efficiently and safely inactivates airborne viruses SAFE FOR SKIN AND EYES Based on study and in our experience as well, using UVC Light 222 issafer even in manned area because it’s radiation cannot pass through easily in the tear layer of the eye and the skin layer of the skin. This study by Bernard et al concluded that skin damage documented by Woods et al arose from very low intensity source emissions above 230nm due to the lack of an optical filter (as low as 3% above 250nm). These wavelengths were emitted as the 222nm Far-UVC emitting device did not utilize an optical filter to eliminate wavelengths outside the 200nm to 230nm range (the safe wavelengths), with wavelengths below 200nm and above 230nm being unsafe. Woods et al hypothesized that a small amount of longer wavelength UVC light above 250 nm (<3%) may be contributing to the observed effects. The study concluded that damage was induced on human skin. In 2014, Woods et al undertook a first‐in‐person study to assess the effect on skin of a 222nm Far-UVC emitting device (a disinfection wand). Participant Information Sheets for both stages of the study can be found on the NHS webpage.This study by Barnard et al emphasizes the importance of using an optical filter to ensure 222nm Far-UVC safety, proving that filtered 222nm Far-UVC is safe but unfiltered 222nm Far-UVC is not.

Participants who successfully complete the study will receive payment of £500 in recognition of their time commitment. 1-48 of 973 results for 'far uvc light' RESULTS Price and other details may vary based on product size and color. The illuminated areas will be observed visually and small skin biopsies will be taken from test sites numbed by a local anaesthetic.
Volunteers, who should have a skin type that tends to burn in the sun, will have small areas of their back/upper buttock illuminated with Far-UVC light over a few days.
Based on their results, the researchers estimate that continuous exposure to far-UVC light at the current regulatory limit would kill 90 of airborne viruses in about 8 minutes, 95 in about 11 minutes, 99 in about 16. The current study aims to increase the number of individuals taking part and is expanding the range of Far-UVC exposures while looking at additional markers for skin cell damage. The researchers found that more than 99.9 of the exposed virus had been killed by a very low exposure to far-UVC light.

The research being carried on in this early-stage clinical trial is building on previous work completed at the University. However, because bacteria and viruses are smaller, Far-UVC can penetrate and inactivate them. Far-UVC light cannot penetrate even the outer (non-living) layers of human skin or the eye. However, before widespread deployment of Far-UVC devices is established, we need to know more about the effects of the technology on the human body, in particular the safety of Far-UVC.”įar-UVC light has the ability to efficiently inactivate bacteria and viruses without causing harm to exposed human skin due to its strong absorbance in biological materials. It could also be useful in fighting antimicrobial resistance. “This technology could have an impact on not only the transmission of Covid-19 but also other diseases like influenza and tuberculosis. We are doing part of this safety assessment by studying the effects of Far-UVC on people’s skin to look for any adverse reactions. “However, we need to do all we can to make sure that Far-UVC light is safe for human exposure. This could be used as a way to reduce transmission of Covid-19 and other infections in the future. Professor Ibbotson said, “This research could have a significant impact for the wider application of Far-UVC light to disinfect the air in public places, such as shops, cafes, bars and offices. They want to hear from healthy individuals who are prone to getting sunburnt to help determine the safety of the technology, which could have a significant impact on Covid-19 prevention. The team are currently looking for volunteers to participate in stage one and two of the trial. The researchers, led by Professor Sally Ibbotson, Head of the Photobiology Unit in the University’s School of Medicine, are carrying out this clinical trial to firstly establish safety and explore the potential applications of Far-UVC light. Special bulbs that give off Far-UVC light can be used to disinfect the air in public places, such as shops, cafes, bars and offices.
Far-UVC light kills bacteria and viruses, including the coronavirus that causes Covid-19 and drug-resistant bacteria on surfaces and in the air.
