There is a lot of media coverage about the possible
dangers of cell phones. I think that the real public
health issue is cell towers and workers being exposed
to very high levels of RF radiation (higher than
the fcc IEEE/ANSI standard). A cell phone may put
out 300 milli-Watts, but a tower may transmit at
several hundred Watts continuously. Think of the
roofer, the HVAC repairman, or the firefighter who
unknowingly stands in front of an antenna head.
I think this is very big issue for the Cell companies.
Any thoughts?

Greetings Nathanvoite:
I get quite a few calls from strange people
looking for information. One not too long ago was
from a lawyer in Brooklyn who claimed to be representing
a client - a septegenarian - who was suing a cell
tower company for installing a tower on the roof
of his appartment building. He lived on the top
floor, directly under the tower, and claims to have
been experiencing severe medical maladies ever since
it was installed. Symptoms included headaches as
well as skeletal joint aches. I kind of dismissed
it as some huckster with his reptile lawyer just
looking to make a quick buck - even suggested that
the next doctor his client saw might want to be
a psychologist
Maybe the poor guy really was being cooked
by the tower. I can believe that a poor installation
would possibly direct some of that energy in his
direction, but you would think that if it were enough
to turn him into a crispy critter, that the service
company would detect the loss in power (i.e., customer
complaints about call quality). Hmmmm......
The lawyer pestered me for two or three
days looking for references and resources. After
spending quite a few hours of my time talking to
him on the phone and providing a lot of information,
I never heard from him again. Never once did he
even thank me for my effort. That's why I generally
detest lawyers (and most headhunters).

Hi Kirt Because I claim to be a telecom consultant,
not surprisingly there have been many attempts to
drag me into this controversy. I only resist
doing this "ProBono" by remembering something a
rapacious CEO once brazenly claimed to my very face:
"Since the abolition of slavery, the most easily
exploited human being is the engineer."

I think it all comes down to the standard.
If a worker can prove that he was exposed to
RF Radiation above the standard set by IEEE/ANSI
and FCC
http://edocket.access.gpo.gov/cfr_2004/octqtr/pdf/47cfr1.1310.pdf
Then that worker has claim on the FCC Licensee
and/or property owner. I don't take claims
of people "Feeling" the RF hurting them very seriously.
Third party workers however, frequently come into
close proximity to antennas. Since they may have
zero RF training, they may not even know a hazard
exists.

This is an Alaska Supreme Court case where a worker
was awarded full disability because he was exposed
to RF slightly above the FCC limit.[/url][url][/url]

That's pretty sad, and totally believable.
Just remember that a lot of the fodder for Dilbert
comics are provided to Scott Adams by real-world
engineers. Regarding serious exposure to
RF, I told this story in more detail somewhere before,
but here is the short version. Back while
in the U.S. Air Force as a radar technician, the
Sgt. assigned as my trainer was giving me instruction
on how to align the circular polarizer on our S-band
search radar system. The guy was a stickler for
safety and doing things by-the-books. After setting
all the safety switches and hanging warning signs
all over the place (no actual lock-outs), we climbed
up to the antenna on the roof. He threw the safety
switch at the top of the ladder to disable the antenna
rotation motor. Aligning the circular polarizer
involved using wrenches and some feeler gauges.
Adjustments were made from the front of the feed
horn. He sat down, spread out the tools, and after
give me some verbal instruction, set about taking
the cover off the feed horn. A moment after getting
in front of the feed horn, he pulled back quickly
and asked me if I heard a strange sound. No, I hadn't
heard anything. He swung back into position and
immediately pulled back again. Sarge was shaking
his head and commented about the loud noise he had
heard again. Suddenly he got up and rushed down
to the transmitter and discovered that it was still
powered on. That was not a happy sergeant. No one
else was around, so he must have been responsible
for the Tx being on. Poor guy, he was really freaked
out for a few days - probably expecting to die suddenly
at any time. I know that he lived for at least three
more years until I got out of the service.
It is scary what we are all capable of doing
to ourselves, regardless of how careful we are.
