While mobile internet is becoming faster and faster, I still hear a lot of people complaining about mobile network coverage. A lot of those problems could be overcome by placing more cell towers, but olso by bumping up the strength of the waves they emit.

There's been a lot of protest a couple of years ago, when in Belgium (where I live), there were plans to build a cell tower close to a primary school, many parents were concerned about the helth risks for the children. Personally, I'd like to get more clarity on the effects of radio waves, so that we can take precautions if necesary, and otherwise stop inexistant risks from hindering the advancement of technology.

Smaller cells means lower transmit power, and thus lower human exposure.
This is because radiation power follows an inverse-square law with distance (at least for longer distances beyond a few wavelengths), so you need higher power to reach a more distant base station.

As I understand it, any potential danger comes not from the cell tower, but from the mobile phone, which is held very close to the head, and its field there will be orders of magnitude stronger than you'll get from the cell antennae. The phone also may boost its signal to communicate with distant towers, so as evan_au says, more towers with smaller cells will mean less signal boosting by the phone, and therefore less potential harm. More modern systems are more energy efficient than older ones, so should be potentially less harmful.
