If your eyes are exposed… you know that gritty feeling you get if you look at the sun? It’s like 10 times, just after a few seconds. model for UV radiation (200-400 nm) that incorpo-rates dust and more recent data for the solar spectrum, gas absorption, and UV surface albedo. 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. At higher latitudes, the sun is lower in the sky, so UV rays must travel a greater distance through ozone-rich portions of the atmosphere and, in turn, expose those latitudes to less UV radiation.

“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. absorb the UV radiation as it passes through the atmosphere. There are many types of radiation, ranging from very high-energy (high-frequency) radiation like x-rays and gamma rays to. Radiation is the emission (sending out) of energy from any source.

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. Ultraviolet (UV) radiation is a form of electromagnetic radiation that comes from the sun and man-made sources like tanning beds and welding torches. 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.
