......Jim Beal has invited me to review his recommendations below....
In keeping with the spirit of the message I just sent to Mariana Tupper --
I do not consider that I can improve upon what Jim has offered..... He,
too, as I would, is speaking from the perspective of an educated guess....
And he is as well informed as I about this matter.....
Others who might want to refine Jim's suggestions are encouraged to do
so......
We (who are not really qualified) are trying to fill a gap that has been
left by governmental (and professional) agencies that are not doing their
job...... So, please allow for that fact.....
Cheerio......

>From what I understand about emf from computers and shielding it would seem
the best approach would be for you to purchase a laptop with the largest
screen you can afford.....(but don't use it in your lap!) PLUS a transparent
glare screen with electric field (EF) ground capabilities...Almost all
computer stores and large office supply stores carry these screens in various
sizes for anywhere from $40-60, depending on size. These screens are for
regular VDT monitor screens from 15"-21", but are especially useful on laptop
screens. Laptop screens use liquid crystal display (LCD) technology. LCD
Screens are activated by strong electrical field gradient changes and have
practically no EMFs (you still get some EMF from the hard drive motor
(that's why you don't want the laptop in your lap). Also, it is VERY
important that the laptop and EF screen be well grounded. You could still
keep your old computer if it is still useful and switch the glare
reduction/EF ground screen back and forth betwen monitors.
BTW, if you are using an external stand-by power supply with your computers,
to avoid losing data during a power failure, keep it as far away from your
disk files and your body as possible......many of these systems have the
strongest fields around them of any computer accessory! (plus a lot of
square wave output....which can affect your floppy disks if you put them in
the vicinity....and there is some evicence that pulse-type square wave a.c.
may have biological long-term effects on your health).
As far as excessive EMFs around your apartment, you can get a rough estimate
of intense areas using a cheap a.m. radio (less than $20 from Radio
Shack)...Just set the dial where there is no station, turn volume up halfway
and start with the field around the transformer in back of your TV or VDT.
Turn the dial until you get the loudest interference noise and then use that
rough calibration to find other places around your apartment where intense
fields exist......Be especially careful about strong fields around your head
where you sleep...pull bed out from wall and keep electrical items at least
four feet away from your head and body (rule-of-thumb). Use incandescent
lamps to read by with bodies entirely of wood, glass or ceramic.
Hope this advice helps a little.
