Is 100 milliwatts a good typical figure to use, then for cell phones? Just
on a knee-jerk basis, it seems a little low.
Anyway know the power output on cordless phones?
Thanks, Max

No, What I was saying was that as a microwave engineer, one
of my red flags
was the eyes. The eyes are the most sensitive to microwave
radiation.
Now, to apply my statement to cell phone use is not correct.
The typical
levels and frequencies of microwave radiation are much
greater than cell
phones.
I knew an engineer who worked with big dish antennas. He
was responsible
designing and testing the antennas, so he was in strong
fields for years.
These antennas had 26 dB gain with a narrow beam, far
stronger that a cell
phone. He worked over 20 years with this exposure on a
daily basic. At age
43 he had cataracts, about 25 years sooner than general
population. Now he
is fine today, retired a few years back.
What I am saying is that at that level of exposure it took
over 20 years to
damage the most sensitive part to the body. Were talking
about 5 watts of
power at 6000 MHz. which is far worst than a 100 mill-watts
at 800 MHz.
In summary: I think a lot of "Bad Science" has been applied.
The levels and
frequencies are too low to cause the kinds of brain damage
being reported.
P.S. I'm an old microware engineer of 51 who used to work
with 3.5 Kilowatt
microwave transmitters for years and I don't have cataracts.

Al,
You've posted a very intriguing statement. Why "the eyes go
first? (In the
past, I got watery eyes and a headache while doing immunity
tests).
"microwave engineers understand the risks" - than what the
fuss is all
about? Or are you saying that since one has not got
cataract, he/she is
safe?
Regards
