![]() ![]() Thanks to this, UV-A lamps have a long tradition in the entertainment business, but are also used in forensics – for example in marking banknotes. The light can cause certain substances to fluoresce. UV-A: UV-A radiation has a wavelength between 315 to 400 nanometres.UV radiation is divided into four ranges according to its wavelength: Depending on the type of UV radiation, this lies between 10 and 400 nanometres. Compared to visible light, ultraviolet radiation, UV radiation for short, has a significantly shorter wavelength.

It’s like 10 times, just after a few seconds.” The release from our Ministry of Science and Technology does not state the wavelength or duration used, but mentioned that the product was tested for more than 99% disinfection.ĭan Arnold, who works for UV Light Technology, a company that provides disinfecting equipment to hospitals, pharmaceutical companies across the UK, told bbc.com: “UV-C is really nasty stuff – you shouldn’t be exposed to it…It can take hours to get sunburn from UV-B, but with UV-C it takes seconds. “UV-C radiation used in this device could be harmful to the skin and eyes of the living beings, therefore the operator of the device must use spectacles with UV-C radiation protection and use this device safely,” noted the paper published in June 2020. Researchers from the Indian Institute of Technology-Kanpur, who developed a portable disinfectant device that used UV-C radiation (222-254 nm), noted that the device was specifically developed to disinfect non-living things. These results are important for the development of novel sterilising methods to contain SARS-CoV-2 infection,” write the authors.Ĭlick here for more Is it safe for humans? “A complete inactivation at all viral concentrations was observed with 16.9 mJ/cm2. The study was published in September 2020 in the American Journal of Infection Control.Īnother study published in Scientific Reports in March 2021 noted that UV-C irradiation was highly effective in inactivating SARS-CoV-2 replication. There is very limited data on the required wavelength and duration needed to inactivate SARS-CoV-2.Īn in-vitro experiment conducted by Hiroshima University researchers showed that 99.7% of SARS-CoV-2 viral culture was killed when exposed to 222 nm UV-C irradiation at 0.1 mW/cm2 for 30-seconds. They showed that 222-nm, known as ‘far-UVC light’, efficiently kills airborne human coronaviruses – alpha HCoV-229E and beta HCoV-OC43. A paper published in June 2020 in Scientific Reports noted that UV-C radiation can destroy the outer protein coating of the SARS- Coronavirus. ![]()
