The height of most adults would make them resonant somewhere near, or in, the FM broadcast band. I'd expect energy transfer to be more effiecnt from the FM broadcast antenna to the human body than it is in the AM broadcast band. I'd sure think so. On the other hand, the FM signal is radiated from an antenna atop the tower. Stand at the base of a 300' FM tower, and you're 300' from the thing that radiates. At an AM station, the entire tower radiates. One of the issues with most FM arrays with gain is that, for many, the spacing which results in the array having gain also results in a fairly pronounced hot-spot directly above the antenna, where few people would be expected to be, as well as directly below, where technical personnel might spend a substantial amount of time. Personally, I think that the AM radiation hazards are overstated in this study, and that the issue comes more from environmental circumstances by virtue of the fact that many AM transmitter installations share the same area as other industrial concerns. -- ----------------------------------------------------------------------------- If there's nothing that offends you in your community, then you know you're not living in a free society.
