2.  1.MAGNETIC RADIATION
 Computer and television screens, function on the principle
where a beam of fast electrons sweep the fluorescent surface of the
screen, where, point by point, it draws a luminous image. This would
not be a problem if the energy from the electrons was limited to
providing the image. But some of this energy escapes in the form of
radiation at various frequencies, in particular VLF and ELF (very low
frequency and extremely low frequency) fields.
The spot of electrons which sweep the screen generates what
scientists call PEMR (Pulsed Electro-Magnetic Radiation) which, at
close range, disturbs the balance of all living cells. It has been
established that the harmful effects of PEMR exist all around the
screen, especially in front of and behind the tube, effects which
persist several hours after the computer or TV set has been turned
off.

3.  magnetic radiation-around the computers or
laptops on batteries is arround 300-350
while on mains it increases from 1500-1900
electric or magnetic radiation.
 only way to know this emit higher levels of
radiation is to measure them with an EMF
meter. The problem with laptops is improper
use.

4. 2. radio frequency radiation, or RF radiation. More and
more computers, particularly laptops are equipped
with WiFi. This means we are being exposed to
another layer of electrosmog from two sources.
Firstly from the laptop itself; most laptops are
configured by default to be in WiFi mode, so even if
you are on a hard wired Internet connection your
laptop is still emitting and receiving RF radiation.
Secondly there is the RF radiation from the
modem/router.
3.Artificial light from computer screens are another
problem which effects the person generally.they
tinker with brain chemicals that promote
sleep.artificial lights lowers the levels of melatonin
hormone which regulates our internal clock and plays
a role in sleep cycle.
It also raises the risk of obesity,diabetes mellitus.

5.  stress, disturbances.
 headaches,  abnormal general fatigue,
 irritability,  neuropsychological
 insomnia, disorders,
 eye strain,  increased absenteeism,
 eyesight decline,  loss of productivity,
 abnormal general fatigue,  declining ability to
 decrease in productivity concentrate and to
and in the natural memorise,
resistance of the immune  aggression and scholastic
system, problems in prepubescent
 decline in libido, children,
 disorders in the  predisposition to
menstrual cycle dyslexia, and
 , and hormonal  lowered spermatogenesis

6.  the best way to cut down on your exposure to magnetic radiation
from your laptop is to use it on the battery instead of the mains
power supply.
 to replace your WiFi installation with a hard-wired
connectionand make sure the WiFi function is disabled.
 Not to use on knees or laps.
 The monitor is usually the biggest problem, not the CPU, so sit a
bit further from the computer screen. This will mean that you are
exposed to less radiation, especially if you sit at least two feet
from the screen – electromagnetic radiation exposure decreases
significantly with distance.
 Limit computer use before sleep.
 dimming your computer screen as much as posible.

7.  If you are using a desktop you can use a radiation filter over the
screen or better still purchase a degaussed screen.
 NASA who discovered that cactus plants have the ability to
absorb the electromagnetic radiation coming from the computer.
 Salt crystal lamps supposedly help cancel out
 the electromagnetic radiation
 By simply washing your face after using the computer can
remove the radiation that has settled there. Our faces are
usually the closest part of our bodies to the screen, and the
particles of radiation will attach themselves there.
 Go wired; wired mouse, wired keyboard and wired peripherals.
Even if you are using a laptop using a wired external keyboard
will significantly reduce your exposure to the EMFs emitted by
the electrical components situated under the keybaord of the
laptop.
 If you work in an office where there are several computers, make
sure you are not in close proximity (a meter or two), to the back
of someone else’s PC screen.

8.  The EMF-Bioshield® system, consisting of two mini-
spheres of white polypropylene to be attached to the
screen, uses the properties of electromagnetic resonance
of rare earth elements (lanthanum, positions 58 to 71 of
the Mendeleiev Periodic Table of Elements). As in
acoustics, where it is easy to create silence by recycling
the same sounds to be cancelled but reversed in
phase, the elements contained in the EMF-Bioshield®
mini-spheres oppose the biologically harmful screen
frequencies with frequencies or the same form and
amplitude, also reversed in phase. The result is called a
counter-phase resonance, which eliminates all harmful
biological effects. EMF-Bioshield® is thus the only
protection system that works globally - guaranteeing the
respect of the screen user's health at work or at
home, irrespective of the position or size of the screen.

9.  In 1984, Professors Johansson and
Aronsson (Sweden) established that
after four hours in front of a
cathode-ray tube screen, the
normal curve of adrenaline (the
stress hormone) excretion reverses
itself Almost as if the body, under
attack by the PEMR, was retaining
its adrenaline to better face it.
These researchers discovered that
after several hours, a screen user is
placed “under stress” by his screen
and experiences a hormonal
malfunction from the saturation of
adrenaline. These studies were
published by the WHO (World
Health Organization) back in 1987.

10.  In 1986, Professor Mikolajczyk (Poland) established that
the female personnel of the Polish airline company LOT
exposed to the PEMR of VDTs had a 125% increase in
miscarriages compared to the female personnel who were
not exposed to the radiation generated by computer
screens.
 In 1988, the French magazine Le Point published a report
on the work of Dr Marilyn Goldhaber from the Kaiser
Permanente Institute of California. Her study followed
1,783 women for three years and observed a 100%
increase in miscarriages in those who spent more than
twenty hours per week in front of a computer screen or
television. The article added that their children had 40%
more genetic defects than the “normal” average of those
who did not work in front of a VDT.

11.  In July 1990, the American
magazine Macworld published 19 pages on the
subject of Pulsed Electro Magnetic Radiation
emanating from cathode-ray screens in the
articles “Is Your Computer Killing You?”, and “The
Danger of Magnetic Fields”.
 More recently in August, 1998, a group at NIEH
(National Institute of Environmental Health) in the
USA studied the effects on health of very low
frequency electromagnetic fields (PEMR ELF/VLF
50/60 Hz) at the request of the American
Congress. They concluded that there were
possible carcinogenic effects for human beings
