As far as I know the exposure is a bit like a bell curve.
Right besides the tower you're in a blind spot, then it gets more intense as you move out of the blind spot and then it gets lower as you move further away.

> 5G will require cell antennas every 100 to 200 meters, exposing many people to millimeter wave radiation. 5G also employs new technologies (e.g., active antennas capable of beam-forming; phased arrays; massive inputs and outputs, known as MIMO) which pose unique challenges for measuring exposures.
It can use more towers at higher frequencies in really really crowded areas or industrial setups, but those work at lower power outputs, and penetrate the body less (due to higher frequencies).
Now compare to AM/FM transmitters that cover a huge geographic area. Those can be scary. FCC allows up to 50000 W transmission power. It's required because the antennas are spaced so far apart.
