The CEO of Xenex Disinfection Services explained to Fox News on Wednesday how ultraviolet light can disinfect the coronavirus on masks in “about two minutes.”
“Different germs are vulnerable to UV light at different wavelengths,” Morris Miller told “Fox & Friends First.”
Cedars-Sinai Medical Center in Los Angeles said Monday that a research team is in the "pre-clinical stages" of developing ways to harness UV light to treat viruses and bacteria, though such technology has not been tested on patients.

It must be banned because orange man bad.
Every ER in this country has UV lights BY LAW. Required to prevent the spread of TB many decades ago.
UV kills the virus, the media forgot to report this as they were too busy twisting Trump’s words.
Here’s a tip, if you are visiting an ER and you see a “blue light” pointed up at the ceiling, don’t climb up there and look into it. It will quickly burn your cornea like a welder.
You will not see anything about experimental technologies to use UV light in treatment, on youtube or twitter because...orangeman bad
Don’t ask how I know but I seemed to have learned far too much from “experience”. I really did spend far too much time in ERs as a young guy.

Interesting local custom?
well, sometimes spell check is not our friend.
If I remember correctly, hospitals were using robots to go around rooms and surgery suites and flood them with UV light years ago. Did they stop doing that?
UV light great for sterilizing surfaces, however not great for shining on skin or eyes

Just think sunburn from hell
“Big, bright beautiful light”
For UV, the shorter the wave length, the less depth of penetration. The newer UV light source of 222 nanometer wavelength does not get past the dead cell layer of human skin, nor through the tear layer of water coating the cornea of the eye.
An extreme example of frequency dependent property would be Extreme Ultraviolet Light (EUL) used for lithography of semiconductor chips (etching with light.) In air the free path for absorption is about a tenth of a millimeter (forty-thousandths of an inch.) By necessity, the processing is conducted in a vacuum chamber. Only front surface mirrors are suitable as the focusing optics. Wavelengths shorter than about ten nanometers reverse the trend and become more penetrating, the so called Soft X-Ray.
The other end of the UV spectrum, UVA, is the more penetrating frequency of light within ocean water (if free of microscopic life.) If bacteria and/or plankton are present, then blue light wins. We can’t perceive UV light and only see the color shift to blue with depth—some ocean life is sensitive though.
Good to know, previously trained to treat UV with caution
I’ve been installing the UV systems in HVAC units since the late 1990s
Not for expensive but the tubes need to be replaced every couple years
