When I was in radio, and we were doing transmitter readings, we were always told to limit our exposure to RF.

If that's true, then we are all dead. Think about the EM emissions a modern civilization puts out as a matter of course: AM and FM radio, microwave communications towers, cell phone towers, satellite transmissions, shortwave radio, radar, VHF and UHF signals, and wireless networks just to name a few. All this artificial EM energy is floating around pretty much all the time.

Yup. But you're not putting it next to your head pretty much all the time.
