Non-ionizing radiation is electromagnetic radiation, like HF - UHF radio
waves, that doesn't have enough energy to knock electrons off of atoms.
X-rays, Gamma rays, ultraviolet light, etc., is ionizing radiation. We
know ionizing radiation can be dangerous.
Some people think that non-ionizing radiation is dangerous too, so for
example they tell you not to hold your cellphone to your ear for 20
hours a day. In Israel, in response to national hysteria about the
'danger' from cell towers, the government passed laws requiring approval
of all transmitting antennas.
A ham is supposed to file an application, including calculations of
field strength at various points around his antennas, and it has to be
approved before he can put up an antenna (or even request planning
permission for an antenna).
In the US, the FCC has an "RF safety" requirement but it's just pro-forma.

I shudder to think, but must ask: What is a "non-ionizing radiation
permit?"
