Hi Dave,
Two (at least) factors have to be considered. One is how far you are
from the source, but the other is how *strong* the source is. Years
back, before my sister appropriated my EMF meter
I went thru the
house measuring the fields put out by this, that and the other. What I
found was that the laptop's field was very small, not a strong one.
Our desktop at that time was a CRT type, which had a HUGE and very
strong field. Then our newer, flat-screen desktop was somewhere in
between, tho I don't remember exactly where along the continuum, except
noted that face about 18 inches away is pretty much "in the safe zone",
but the way my son liked to work, with his face much closer to the
screen, appeared to be pretty much cooking his head. (Well,
tongue in cheek...)
If the laptop is *in the lap*, then yes, your thighs are probably
getting a good dose of magnetism (that's all I was measuring). Even
putting it on a pillow should make a big difference from that
standpoint. And if you have your laptop sitting on a table, then the
field is pretty negligible--at least according to my measuring and
understanding.
The strength of the magnetic field is directly proportionate to the
strength of the electrical current running the machine. So a computer
(or refrigerator or whatever) which uses a lot of energy to run, will
put out a stronger (and therefore larger) magnetic field than will one
that draws only a smaller current--such as a laptop. (Dave, I know
you're familiar with this, but perhaps someone else will find it
useful!)
