1G, 2G, 3G and 4G use between 1 to 5 gigahertz frequency. 5G uses between 24 to 90 gigahertz frequency. Within the RF Radiation portion of the electromagnetic spectrum, the higher the frequency the more dangerous it is to living organisms. …Sounds like hype. Those frequencies are far lower than visible light (385-750 terahertz). Ionizing radiation has higher frequency than visible light, although a larger infrastructure of RF transmission can produce heating effects. (X ray frequencies are between 30 petahertz and 30 exahertz.)
It's basically mandatory to use some form of lead shielding for areas of the body not being xrayed, even with seconds exposure to xrays.
The 5g network, presumably, will be emitting 24x7.
At what point do those increases of frequency and constant exposure become a concern?
