Electromagnetic fields, 5G and health: what about the precautionary principle?

New fifth generation (5G) telecommunications systems, now being rolled out globally, have become the subject of a fierce controversy. Some health protection agencies and their scientific advisory committees concluded that there is no conclusive evidence harm. Several recent reviews by independent scientists, however, suggest significant uncertainty on this question, with rapidly emerging potentially harmful biological effects from radio frequency electromagnetic field (RF-EMF) exposures, at levels 5G roll-out will entail. This essay identifies four relevant sources concern: (1) lack clarity about precisely what technology included in 5G; (2) accumulating body laboratory studies documenting disruptive vitro vivo RF-EMFs—but one many gaps it; (3) an almost total (as yet) high-quality epidemiological adverse human EMF exposure specifically, but such past generations RF-EMF exposure; (4) persistent allegations some national regulatory authorities do not base safety policies latest science, related to unmanaged conflicts interest. The author, experienced epidemiologist, concludes cannot dismiss growing concerns RF-EMFs, especially era when higher population are occurring widely, due spatially dense transmitters which systems require. Based precautionary principle, author echoes calls others for moratorium further pending more research safety.
