Reply to comment by CarneDelGato in If UV radiation is used to disinfect and sterilise things then why isn't everything the sun touches (your skin, the sidewalk etc) sterile? by Critwhoris

For the sake of anything

U.V from the sun is inherently filtered out to a very large degree by the atmosphere, you cant get around that on the ground.

U.V we generate with whatever technology is only subjected to what we decide it to be.

Okay, sure, but we generate a heck of a lot more radiation that isn’t actually harmful. You won’t get burned by a wireless router.

Yes, but if you stand inside a hospital air handling unit with UVC sterilization lamps with exposed skin you'll have severe burns in a few minutes.

Right but this is specifically about the radiation we create specifically for sterilization. We're not talking about all human made radiation, just the kind we use for disinfecting.
