    If it only takes 30 seconds to disinfect maybe you could do it a couple times an hour in an occupied room. That’s not much exposure, I’d think. We don’t put on sunscreen every time we go to check the mail, for example.

    How about a UV light that comes on periodically when no one is in the room? It couldn’t just be a reverse motion detector because you wouldn’t want a stationary person (possibly sleeping) to be exposed.

    UV-C radiation is very dangerous and not practical for use outside of controlled environments like laboratories, hospitals, sewage treatment plants, etc…

      Yes, AND it will only disinfect areas actually touched by the light. Example would be any 3 D object where light touches the top surface, but not the rest. Light would have to stream from multiple angles. Anything not touched would still be contaminated.

      I see this as a tool, but part of an arsenal and not for generalized usage.

    There are certain skin conditions that can be treated with UV radiation. With modern phototherapy, successful treatment of eczema, dermatitis, rickets, atopic and localized scleroderma, jaundice, psoriasis, and vitiligo is now possible.
