Dear Jason,
While on rooftops and on towers working with the cellular BTS
antennae we are required to wear NARDA RF detectors that
beep when the radiation gets to them.
In training to qualify for RF radiation "hot work," we are told that
a field of 50 milliwatts per cubic meter is the threshold for out
personal alarms.
In the three years that I've been on the project my radiation detector
beeped once when I was on the Alpine Tower on the banks of the
Hudson (there are over 200 RF sources on this tower) and one
other time when I climbed near an AT+T transmission horn.
Now I never tempted fate to put myself in direct line with any of the
850MHz or 2GHz radiators to see if the alarm worked, but I remember
someone aboard ship, some thirty years ago, throwing a raw egg up in
front of the rotating radar antenna and it blew up.
We are warned to stay a minimum of ten feet ( ~3m ) from radiating
sources at V, U, and SHF frequencies.
However, I cannot advise you on HF radiation Craft as our discipline
was way above.
Respectfully,
Hal Mandel
