Re: The Biological Effects of Weak Electromagnetic Fields

SArjuna
I would like to hear from people who think they are affected by the
lights in their flat screens re. what happens if they use their computers on
battery only, which does away with the frequencies created by the transformer as
well as those in the electricity provided by lthe electric utility company.

As I am extremely sensitive to high frequencies but am able to use my
laptop for hours as long as I use it on battery only, I am sure that many other
ES folks could do the same.

Flat screens and flat screens are quite different.

I have measured a number of flat screens (TV) in stores, where they are
running the same TV-program.

Even in the same brand (f.i. Sony) but in different size, there are great
differences.
F.i. a 37" gives more elektrosmog than a 42", measured on the screen.

And what you see on the screen may give differences also.

I have found, that on a Philips 42" flat LCD screen, the elektrosmog is
less, but when a satellite tuner is connected, it gives a little bit more,
but when the menu of the satellite tuner is displayed on the screen, there
is a lot of elektrosmog.
Mostly signals between 5 kHz and 150 kHz, and mainly around 30 kHz.

Some TVs and computer monitors may work like a secondary antenna, and they
transmit signals, even when they are not *on*. (I found this also with LCD
monitors of f.i. Compaq.)

I have placed the sound of a starting Dell Notebook on:

So, there may be differences between several notebooks.
And perhaps the programs you are running on them!

PAUL UK REPLIES -
Having tried numerous LCD tvs, set top boxes etc.. I have long since
realised that chosing one based on size, power consumption, is futile its a trial
and error feild test that reveals wether it will give negative reactions and
of course this brings terrible inconvenience to all concerned, refunding
worries, transportation of equipment etc..

What is the general concencus of oppinion on Plasma Tvs, my brother has a
42inch plasma and surprisingly it does not give me a rapid reaction despite the
size and proximity ? that said I have never been around it for more than 5
mins.

I think that Charles is near the mark with the secondary transmitter thingon
LCDS etc its probably the same for all similar technologies. I think that
the boxes on many appliances are not so very well RF sheilded certainly not
from a machine to human interface, maybe machine to machine, ESSERS are not
part of the equation yet.

As far a Laptops on batteries are concerned I get a reaction wether its on
battery or mains. I have a Dell Inspirion 1300 with 3 pin transformer, so its
suppossed to be better due to the earthing.

Yes, I do as well. While Shivani is correct that using it with a battery
avoids bringing in noise from the AC power lines and the laptop's AC/DC
transformer, you still have the noise from inverter which powers the
florescent backlight.

These days, there are an increasing number of laptops which replace the
florescent backlight with LEDs. These laptops (presumably) don't have
an inverter, and may be (or may not) be easier to tolerate.

I'm not so sure.
The laptop I got, (an IBM Thinkpad 2628 I got for datalogging from the
Spectran),
I can still feel from across the room. On battery too.

However, I do know SOME transformers are very annoying, perhaps that
might be the case for your AC-DC converter?

For example, 7 years ago I got a composite-to-VGA signal converter to
watch vcr tapes on VGA monitor because I could not stand the TV. It was
a spectacular failure, because the converter was a loud broadcaster of
electrosmog, but it was not as terrible when I swapped the 9V
transformer for the 9V transformer with my USR modem.
The same happened with a different device, brand forgotten, that had a
bad transformer.
