5G is qualitatively and quantitatively different from 4G
The idea that we will tolerate tens to hundreds of times more radiation at millimetre wavelengths is based on faulty modelling of the human body as a shell filled with a homogeneous liquid. The assumption that millimetre waves do not penetrate beyond the skin completely ignores nerves, blood vessels and other electrically conducting structures that can carry radiation-induced currents deep into the body. Another, potentially more serious error is that phased arrays are not ordinary antennas. When an ordinary electromagnetic field enters the body, it causes charges to move and currents to flow. But when extremely short electromagnetic pulses enter the body, something else happens: the moving charges themselves become little antennas that reradiate the electromagnetic field and send it deeper into the body. These reradiated waves are called Brillouin precursors. They become significant when either the power or the phase of the waves changes rapidly enough. 5G will probably satisfy both criteria.
Full implementation of 5G will bathe all of us in a continuous bubble of cancer-causing microwaves. Please sign petition.
