Playing Devil's Advocate, I'd like to remind you that ordinary visible light IS dangerous... if you are exposed to it at too high an intensity, you can receive horrible (sun)burns. If it is concentrated (through mirrors or lenses), you could even be vaporized. At normal levels, radio waves should be safe as well. At very high levels (feet from the transmitter, perhaps), I suppose they could be harmful (part of the reason they are high up and there are fences around the base to keep people out). My only experience with living close to a high-powered (FM) tower is that the signal overrode much of the FM spectrum, causing that one station to tune-in between all other stations and override some of the weaker ones. Annoying, but not enough to cause me to take down the tower.
