Risk is Virtually Non-Existent, and ONLY THEORETICAL...
<1 in Quadrillion = .000000000001% -
When Tested at 10X Limit = Zero Harm

We Don't Need Any MORE Long-Term Studies as Krypton Light Simply Can NOT Penetrate Your Skin! What Exactly Would You Be Looking for When it Physically Can't Enter the Body?
UV Light That Can NOT Hurt You!
Graphic: CBS News Covid-19-Pandemic-UV-C-Light (May 22,2022)
"Far UV... should be extremely safe for occupants for prolonged periods of time. The reason is physics. The amount of UV light simply does not penetrate human tissue sufficiently to cause serious health concerns."
