Yabbut... your examples are somewhat 'trivial' sources compared to some
others to think about.

AndÂ* they leave out the EMF source closest to home, the human body
itself. We capture those EMFs in ECGs and EEGs and use them for diagnosis.

We have to work at making use of those tiny electro-potentials.

It's significant that it's always the most recent technologies that
trigger these fears of invisible perils. We're programmed to be
suspicious of the unfamiliar: better run away from an unknown animal
than stick around and become its dinner.....

Speaking of dinner; your microwave oven has such a powerful source of
emf that we need to be shielded from its damage, by law/regulation.

And, maybe if I were a pregnant female train engineer sitting near the
generator for an diesel-electric locomotive, I might want to use one of
those measuring devices to see what my exposure was like.
