I can't speak about power levels however, most of you likely have 5G in your house already. Dual-band wi-fi routers? Yep, 5G. I would say that at least for now, you are more in danger from holding your cell phone to the side of your head. I would mention that I am a Ham Radio operator so I've learned a few things about radiation safety. Doesn't make me an expert and I am by no means dismissing any possible danger. If you could actually see all the radio frequency signals that have been flying around for decades you wouldn't believe it.
