Far UVC is not carcinogenic (most UV is, this is just a specific wavelength that isn't).
Ideally you'd want to use these lamps in environments that our immune systems didn't evolve for, like crowded conference rooms and school classrooms.
Far UVC is carcinogenic when it reaches living tissue. However, it has a very short mean free path so it doesn't, generally, reach the growing layer of skin. It's less obvious whether exposed mucus membranes (lips, nose, tongue) or the eyes are affected. It probably doesn't reach the lens of the eye, which is good.
I think that is the same thing as saying that Far UVC is non-carcinogenic.
I actually read it as saying far UVC is probably carcinogenic for specific areas of your body (lips, maybe eyes).
I don't know if that's true, but it's what GP suggests to me.
