Is any agency using UV Lighting as a way of disinfecting the buses?
John Gasparine commented
I would not recommend this. It is not as effective as chemical disinfectants (UV light does not work in shadows), there is no good guidance on the "dose" of UV that's needed... it depends on reflectivity of materials, ambient temperature, wavelength of light, intensity of bulb, etc... this makes it really hard to know how to EFFECTIVELY use the technology. Dirt/dust on the surface will also effectively create a "shadow" which reduces the light's ablity to disinfect surfaces under the grime. You may have also heard that the light is harmful to human tissues, skin and especially eyes.
