This sort of thing is the result of the mass hysteria whipped up by the news media and other groups that fail to understand the theory behind radio waves, sometimes conveniently.
To merely call the EM field that is transmitted from an antenna such as that used on a cell-phone tower "radiation" is missing the point.
It is not the same sort of thing as the radiation that comes from uranium or other radioactive isotopes.
References have also been made to microwave ovens, in the debate about cell-towers, however you have to remember that a microwave oven uses power levels in the hundreds of watts, not the micro-watt levels associated with cell-towers.
Radio waves are all around us and have been since Marconi started his experiments in 1895.
Now, the reason these cell antennas are installed so high, is not because of the perceived health risk to people, it is because they use such low powered transmitters and coupled with the fact that they use extremely high frequencies, they need to be high to transmit signals that are by nature line of sight.
