For example, surfaces of door handles, handle bars, or toilet flushes that are not directly in the line-of-sight will not be disinfected.Ģ. High-touch points that are obscured may be missed.

The efficacy of UVGI against a range of microbes has been demonstrated in numerous studies. UVC sterilisers which use UVGI have been applied in the healthcare sector and in research. This method of disinfection has been applied in the disinfection of surfaces and sanitisation of drinking water.

Ultraviolet Germicidal Irradiation (UVGI) is a disinfection method that uses UVC. Ultraviolet-C (UVC) radiation has wavelengths of 100nm - 280nm and is in the spectrum of the sun’s radiation that we are rarely exposed to, as the ozone layer in the stratosphere prevents UVC rays from reaching the surface of the earth.
