BANGKAPOS.COM – Efforts to break the chain of spread of the new coronavirus, SARS-CoV-2, which causes Covid-19, continue to be investigated. One of them is the use of far ultraviolet light or Far-UVC.
Ultraviolet C (UVC) light with a wavelength of 222 nanometers (Far-UVC) has been shown to kill bacteria without damaging mammalian skin.
The Far-UVC beam is also intended to be used by researchers from the Faculty of Engineering, University of Indonesia (FT-UI) who are collaborating with the FTUI Alumni Association (ILUNI FTUI) to develop the Rapid Disinfection Chamber (BDC) -04 as a form of UI contribution to reduce the impact of the Covid-19 transmission.
“The way BDC-04 works is by deactivating microorganisms, bacteria and viruses using the ultraviolet light known as Far-UVC, which has a wavelength of 207-222 nm, will quickly kill viruses and be safe for the human body said FTUI dean Dr. Ir. Hendri DS Budiono, M. Eng, as the launch Kompas.com.
In a trial by researchers at the Radiological Research Center, Columbia University Medical Center, New York, light was shown to kill the H1N1 virus.
In a document that was quoted from NatureOn Saturday (05/02/2020), previously, the Far-UVC investigation (207-222 nanometers) was able to effectively deactivate the bacteria without endangering the skin of the mammals that were tested.
Because, due to the strong absorption of biological materials, distant UVC rays cannot penetrate the outer layers of the skin or the human eye.
Some scientists also managed to show evidence, whether UVC light waves can have a similar effect on viruses, as described in an article in Scientific Reports published in February 2020.
Bacteria and viruses are micron-sized or very small in size, the far UVC can penetrate and disable it.
