There's a small fence around each tower with signage indicating the RF danger. Then around the whole property there's a horse-height fence, with a locked gate. And around that there are a few miles of soggy farmland, so it's pretty low risk.

Site plans have to include certain safety precautions, and fence type, placement, height, etc. are all submitted to the FCC when a tower site is designed or rebuilt.
