magnetic fields

i bought a cheapo GaussMaster to begin to get an idea of the mag fields
near my place. It measures from 0-1 miligauss.
1 milligauss is equivalent to 0.1microtesla. (yes?)
1 micro tesla is what i know the Swiss say is the max allowed for
people to live in there.

The meter doesn't register at all in my general home environment, so
the mag fields in my house are at the very most 0.2milligauss. (away
from electric objects, obviously)

i'm not niave enough to think that even what the swiss say is anywhere
near a safe level from humans to live in let alone an ES. So i'm
trying to find out what a reading of 0.2milligauss means to someone
with ES.???

Re: magnetic fields

I'm suffering from what I can only guess is a reaction to magnetic
fields. I bought 2 meters from LessEMF but they picked up nothing of
note.
After further enquiries I got some infromation from a gent in Sweeden
who told me that the meters available today are not much use.

"(We used to have a good EMF-meter
for sale in Sweden that reacted more like hypersensitive individual
do, but
unfortunately it is no longer in production. It measured the rate of
change
(the dB/dt of the magnetic field = uT/s in one scale and the
displacement
current induced by the dE/dt of theelectric field in nA...)"

Also magnetic fields today come in very high frequencies which meters
do not detect. This is something that was started by (appliance)
companies about 15 years ago.

"Your Tri-Field meter is of limited use as it contains no frequency
information; for most people the 35kHz fields of a fluorescent light
is much
worse that a 50Hz incandescent lamp ( a meter like the one I
described above
would show 35000/50=700 times stronger deflection for a 35kHz field
than for
a 50Hz field of the same strength) ..."

My first post - hope it works!

The TriField is frequency weighted, calibrated at 60 hz.
So higher frequencies do show stronger readings.

An ambient field of 0.2 mili gauss is on the borderline
of being tolerable for several hours of exposure. I
can feel 3-5 mg within seconds/minutes. Unfortunately
there are fields not picked up by such meters that
the ES can sense.

Not the very high ones. Modern equipment uses frequency converters to
change frequency from 50 or 60 cycles/second to thousands, millions and
beyond c/s.

Correct, the magnetic and electric modes of the Trifield meter measure
up to 100k hz, and the RF mode of the TriField meter is rather impotent.
That's why it's important to have a quality RF meter to complement the
general purpose TriField meter.
