This article on Far-UVC wavelengths preceded the Sars Cov2 virus by more than a year. This is the first truly scientific experiment that talks about this 222nm wavelength and its properties against exposed viruses and why Far-UVC is not problematic to humans. I do a bit of UV photography and find it fascinating. I know that there are spectral and UV experts out there that might find this translational science of value.
