I agree, but they still ARE a problem. I was mostly talking
about magnets more than stray EM fields from electronic
devices, and the only way to fix that is to make products
shielded from them, or make products that's not sensitive to
them. In the USA, all monitors now are "Energy Star" compliant
which also might reduce radiation. http://tinyurl.com/6ptk9a

Electromagnetic fields do not have to be a problem.
About 20 or 25 years ago, CRTs emitted a great deal of
radiation, causing
pregnant mommies who were exposed to the radiation for many
hours a day to
spontaneously abort their babies. The fledgling computer giants
were
terrified that a wonderful industry with a great future would
go belly up
(perhaps I should have used a better expression!) and they were
determined
to find a solution. They did - and the resulting and
ever-increasing
Scandinavian TCO standards are so stringent today that there is
nothing to
worry about. Granted, flat screens largely replaced CRTs today,
but that's
not the point - and even flat screens have to comply with TCO
standards.
The industry reacted and solved the problem with one kind of
radiation
because they had no choice. They proved that with determination
it is
possible to practically eliminate the threat of dangerous
radiation.
When it comes down to it, electromagnetic fields are just
another kind of
radiation. The industry solved the problem with CRTs, and they
CAN solve the
problem with solid state media.
It's just an issue of determination and will-power.
