If it's any type of EM field, think about the MRI scanners in a
hospital. The personnel that run those things sit in a HUGE field all
day long. When the MRI runs that field is shifting tremendously. At last
look they wear no monitoring devices of any type. That would tend to
discredit any type of adverse physiologic effect due to those types of
fields. However, you will always find a few who disagree.

Then there is public perception of a risk that may or may not be there.
Remember the big craze about having to have a low radiation monitor a
few years back?

If you owned a computer store you couldn't stock enough of them to sell
to people until one of the local government agencies did some testing
(later confirmed by others) that there was no discernable emf emissions
from the monitor past about 8cm from the glass (if I recall correctly).
The low rad monitors were almost identical (except you could sell them
for more).  I've only ever seen one person who had sight problems
(legally blind) who would have to read text with his nose touching the
glass. Everyone else sits a good arms length away.

I've seen a similar test of the em fields around the hi tension towers.
The field was quite a bit bigger but they claimed to extend only a few
meters around the wire. Ask any farmer who has milk cows if they react
or behave differently when pastured next to towers and they will claim
they do. I had a friend who lived with towers in the backyard. He was
pretty weird so O'm convinced ;-]
