I kept wondering “how does this compare to sunlight” in terms of radiation that reaches the living layers of your skin, etc. Might be worth including that.
Far-UVC’s strongest effect on viruses and bacteria is to damage their proteins, so they can’t infect us. This same protein absorption is what makes far-UVC safe for humans: unlike the UVA and UVB in sunlight that penetrate deep enough to cause sunburns and skin damage, far-UVC is so strongly absorbed by proteins in the dead outer layers of our skin and eyes that it doesn’t reach the living cells beneath. Because of this shallow absorption, far-UVC has minimal effects on the human body, and is safe to install in our homes, schools, and workplaces

Good question! Reworded a bit:
