uv reactive is scientifically harmless. The meaning by that is, all things that are visible reflect/asborb light accordingly...so on a low level, if you can see it you will get some radiation.
But don't freak out, it's the same harmless radiation you get from everyday visible objects....like fruit, books, trees...cat
to better understand it, in natural observation sense...go get yourself a scorpion...they are uv reactive.
and the uv wouldn't really be drowned out...it gives a different spectral resonance, kind of like looking through 3d glasses, either the grey smokey kind or funky blue/red kind
