Again, no quotes. But even as-is the idea of using ultraviolet to disinfect internal surfaces is not bonkers to any degree. Like I could see it working for nasal disinfection.
In fact that's so obvious, that given you get very sad that someone else could even consider that tells me that you don't really know what you are talking about. Ironically, unlike Trump.
Won't comment on the bleach one without a quote though.
have a read for yourself:

As for me, I don't think you need a phd to read the warning stickers on bleach and isoproponal which say "do not injest" [2] [3] or warnings on germicidal lamps that say "do not expose to eyes or skin" [4]. If you do or have otherwise hidden knowledge why these should be ignored, say so.

Next you will tell me that he isnt talking about UVC lamps, and I'll have to admit he speaks so vaguely that you can interpert his own words as almost anything.
It is absolutely bonkers to think about using UV to disinfect human skin, let alone the inside of the human body.
Any UV radiation strong enough to destroy the cells of bacteria is strong enough to destroy human cells. We know that UV-radiaton that's not strong enough to kill bacteria is already harmful to human skin (we call the phenomenon sunburn).
