Subject: RE: Pace makers, speakers, magnetic fields
Just to note a personal experiance -- took a field meter home and
looked everywhere for fields -- worst was next to an old bedside clock radio
with a motor that flipped the numbers on a mechanical display -- next was
within about 6 inches of the TV face, but nothing anywhere else...........

I know that there are entire websites out there devoted to exposure to
60Hz fields and their possible health ramifications. It has been
debated in local newspapers around here because of the "Marcy South"
line that runs through our area on its way to New York City.
My EMC professor (yes EMC is a class at SUNY Binghamton) showed us a
graph of a common household. The 60Hz fields near your average kitchen
stove are much higher than the fields that you would experience under a
large power line. Many people forget that proximity can make up for
raw
field strength.
It would be interesting to know how much 60Hz I'm bathing in right now
as I type at my computer.
Dave, do us a little experiment. Measure the 60Hz fields right at
your
chair where you sit all day in front of the computer. How would that
compare to a power line?

Interesting. A friend and I drove to a house he was interesting in
buying so that we could measure the 60 Hz magnetic fields (it is near
some big power lines). While driving I switched on the equipment and
was
surprised to measure such a strong mag field from the dashboard. I
can't
remember the actual magnitude but it was high.

How many gigatesla are these 'huge' fields?

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.
