If you were to travel to Lodi, NJ and found WABC AM's transmitter site, you could take an 8 foot fluorescent bulb, hold it in your hand (touching ONLY the glass of the tube) and the bulb would be completely illuminated. Of course, YOU would also be exposed to this VERY high RF field. It's an "eye-popping" demonstration of just how much RF energy is radiated at an AM transmitter site like WABC's.
While the current "conventional wisdom" states that this RF field is at a low enough frequency to be "harmless" to humans, *I* wouldn't feel *completely* secure being exposed to such a field on a constant basis.
Back when technicians were manning the DEW Line in the frozen North, some technicians would stand in front of the antennas and be "warmed" by the RF radiation. (The frequencies involved are MUCH higher than AM Broadcast Band frequencies.) It was only later that some discovered they were sterile, or had a higher incidence of cancer rates. In effect, they were microwaving themselves.
I am NOT one of those people who fears cellphone use causing higher brain cancer rates. Nevertheless, I DO feel it is better to err on the side of caution whenever RF fields are involved.

Europe has stricter RF exposure standards than the US. I would not live next to a powerful AM, TV or FM broadcast station.
