I think the main concern comes from the mM-wave frequencies from what I've read. The others are more of the same, but a lot of what I've seen--and I can't remember where at the moment--focused exclusively on the high frequency nodes that would (theoretically) be deployed in urban areas.

People don't realize they're exposed to mmwave already. If you're on a jet or ship, in sight of a jet or ship, near an airport (not just going through a body scanner), near a weather radar station, within line of sight of a microwave relay tower, walking through automatic doors, or driving, your body is absorbing mmwave RF from something. All of those sources are from radar, which is a lot more common than one might think.
