Just because it doesn't ionize atoms doesn't mean it can't have biological effects.

Some bacteria secrete small iron oxide crystals and are able to use those to sense magnetic fields[1]. Our guts are full of bacteria. Wonder if a nearby RF emitter can cause some of them to run amok. They surely tested the effects of cellphones in human tissues, but I doubt the same was done to bacterial cells.

There is preliminary evidence "that MTB in the gut are associated with grey matter volume in magnetite-rich brain regions related to orientation and navigation" [1].

This was explored (and dismissed) in the early noughties [2], when cell-phones-cause-cancer was enjoying a halcyon. (I think it was radiation from CRTs before that. Probably non-organic vegetables today.)

All electromagnetic radiation that encounters some conductive material induces (tiny) currents. Cells are full of conductive materials.
