Inverse square law makes your idea not so practical, aside from the
inherent dangers of exposure to raw UV light!

I'm well aware of this after having used such lamps in the past.


Better to wash the room down with a disinfectant, or simply air it out
for a while...

The problem is that there are dogs and cats present and the room I want
to sterilize is in a relative's house. They own the pets, but I haven't
had a pet in over 40 years. If I were disinfecting my own room, I might
use 70% iso rubbing alcohol in sprayer format or even a weak bleach
solution, but animals pretty much rule out either chemical. At least
with the lamp, there are no residuals other than perhaps weak ozone that
can be aired out quickly.


If the person was very contagious then look up the procedures for
dealing with that rather than making up your own potentially dangerous
ones.

Trying not to make this complicated. All I wanted to do was see if the
lamp was in fact still producing the necessary UVC spectrum. Surely,
there should be something on the market that perhaps fluoresces only
when UVC illuminates it. Or something similar and relatively simple.
