Apparatus of shielding
against the biological effects of nonionizing
-- The disclosed
device comprises a container (1) intended to be placed in the
vicinity of the source of said radiation and containing a medium
(6) which has been subjected to prior irradiation and a metal salt
or a combination of metal salts in said medium at a maximum
concentration of 20 mg of salt(s) for 100 l of medium, said
container being made of a non ferromagnetic material which is
chemically neutral with respect to said medium and salt.
Preferably, the salt is a salt of an alkaline metal or of an
alkali earth metal, and the medium is an aqueous liquid medium.
The invention relates to an apparatus of shielding against the
biological effects of the nonionizing electromagnetic radiations,
in particular those emitted by the domestic, office automation or
industrial electrical apparatuses or electronic.
In particular, the display screen apparatuses (which they are
especially computerised monitors, television sets or terminals
videotex), are considered to produce, because of the
electromagnetic radiations which they emit, a certain number of
biological harmful effects revealed by various organic disorders
such as tires ocular, evils of head, states of stress, etc
One indeed could show that the light radiations from the screen
(embarrassment due to the light intensity, contrast, the
concentration on a fixed image or to the frequency of scanning)
are not the single causes of these organic disorders, but that the
electromagnetic radiations (nonionizing) emitted by these ap
similar also have proven biological effects.
The invention has as an object an apparatus making it possible to
protect itself against these last effects biological, suitable for
the existence of a field of prevailing relatively intense
radiation in the environment of use of these display screens or
other generating similar elements of electromagnetic fields. In
particular, the invention is not limited to the particular case of
the display screen apparatuses, but is also intended to be used
against the electromagnetic fields of all natures, created for
example by the furnaces with microwaves, the lines with high
tension, the cordless telephones and cellular telephones, the
plays video, etc
Various apparatuses were proposed to mitigate the effects of these
radiations, but they proved in practice somewhat effective, and
sometimes same hazardous because some propose to use elements
which produce themselves of the nonionizing radiations, for
example using ferrous webs forming bipolar, technical emitter
whose harmlessness is far from being certain.
In addition, the presumption of effectiveness on the human being
or the animal of the majority of the apparatuses proposed up to
now was not checked by biological experiments or biophysics.
The apparatus of shielding of the invention, on the contrary, does
not emit such nonionizing radiations and it made the biological
test object and biophysics of effectiveness and harmlessness.
N is characterized in what it includes/understands a container,
intended to be laid out near the source of the aforesaid
radiations, containing a medium having undergone a prior
irradiation and a metal salt or a combination of metal salts
carried by this medium with a maximum concentration of 20 salt mg
(S) for 100 1 of medium, the aforementioned container being in a
nonferromagnetic and chemically neutral material by respect to
that the medium and salt.
Preferably, the aforementioned salt is an alkaline salt of a metal
or alkaline-earth and the aforementioned medium is a liquid
medium, especially an aqueous medium.
The aforementioned prior irradiation of the medium can be
beneficial lies realized by use of an antenna To lick placed above
a volume of the aforesaid medium and held with the hand by one of
its branches, or by use of a radiation source coherent associated
means to cooperate with the hand of an operator.
The aforementioned container can especially have the shape of at
least a closed elongated tube at its two ends, for example of two
parallel tubes laid out coast at coast, and length ranging between
10 and 25 cm.
One now will describe an example of performing of the apparatus of
the invention, in reference with the annexed drawings.

another form of implementation of this same method.
Figures 6 and 7
diagrams showing the clinical results of studies carried out to
show the effectiveness of the apparatus of the invention.
On figures 1 and 2, one represented an apparatus of shielding in
accordance with the invention, which is carried out in the form of
two hollow parallel tubes similar 1, sealed with each one of their
ends 2 by an appropriate means (for example a depressed steel ball
3 with force as illustrated on the figure, or by plugging by means
of a crosslinkable elastomer, or by mechanical crimping, etc).
These tubes are maintained, for example in a central region, by a
common carrier 4 allowing moreover the fixing of the apparatus on
an appropriate place of the apparatus which one wants to protect
oneself, for example by means of a pellet of adhesive dual face 5.
Figure 3 illustrates an example of apparatus in accordance with
the invention placed against a lateral wall of a computerised
monitor, therefore near the radiation sources of the display
screen of this one.
The tubes 1 are filled with liquid appropriate 6 which one will
describe the composition further. Tubes 1 must be in a
nonferromagnetic and chemically neutral material (not reagent)
compared to liquid the 6; it can be in metal, for example in
landed nium or an aluminium alloy, or in a synthetic material such
as a polyamide or a polypropylene. In the illustrated example,
each tube has an inner diameter of 4 mms and an outer diameter of
6 mms, with an overall length of 17 cm for an inner length useful
of approximately 15 cm, which gives to each tube a capacity of
about 1,5 to 2 Cm3, value (nonrestrictive) corresponding with the
amount of liquid required to ensure a shielding against the
typically emitted radiations by an apparatus of type monitor to
computer or television set.
It will be noted that the form and the dimensions illustrated on
figures 1 and 2, if they are beneficial, are not essential for the
implementation of the invention, whose essential principle lies in
the nature and the treatment from liquid the 6. Thus, other forms
can be considered, for example spiral, ring, hollow sphere
defining an interior volume having a capacitance of the same order
of size. Moreover, if one envisages two tubes (or two rings, etc),
the materials of the two containers can be different, since they
are nonferromagnetic and neutral with regard to the liquid one
that they contain.
One now will describe the manner whose the active liquid medium 6
is prepared. One will note in this respect this active medium is
not necessarily present in liquid form, but can be it in form
solid, gaseous, gelled, etc
One takes an aqueous medium, for example purified water, and one
subjects it to a pretreatment nonionizing irradiation, for
example, like illustrated figure 4, by means of an antenna of
To lick: this antenna 7 is placed above a container 6 tells nant
the aqueous medium, and it is held with the hand by one of its two
branches (magnetized stems 8), while the dimension of the resonant
loop 9 is adjusted by the movable web 10 at a frequency of
resonance ranging between 0 and 10000 MHZ; the antenna is
maintained by hand 11 of the operator above it container 6 in
order to to realize, of manner in itself known, a resonant
coupling between the operator and aqueous medium 6 and to thus
operate a nonionizing irradiation of this last.
A variant of implementation of the irradiation can be carried out,
like illustrated figure 5, by application of an emitted coherent
radiation 12 by a laser 13 associated means to cooperate with hand
11 of the operator, for example a formed loop 15 in line of supply
14 of laser 13 and in which ltopéra- tor will pass his hand, so as
to still ensure here a coupling between the hand of the operator
and aqueous medium 6 contents in the illuminated container by the
The aqueous medium thus prepared is added with a metal salt or a
combination of metal salts, with a maximum concentration of 20
salt mg (S) for 100 liters of aqueous medium.
It will be noted that the adding of salt can indifferently be
carried out before or after the nonionizing prior irradiation
which one has just described in reference on figures 4 and 5.
The selected metal salt is preferably a salt of a metal belonging
with the formed group by Li, Na, Rb, K, Cs, Mg, Ca, Sr, Ba, Fez++,
Co, Ni, Mn, Zn, Cd, Pb, Cu, Fe++, Ag, Hg, by excluding rare earth
salts preferably and by choosing an alkaline or alkaline-earth
salt of a metal preferably.
In addition, it will be noted that the maximum value of
concentration of salt (or salts) indicated higher is substantially
indépen- dante of the nature of selected salt.
One now will give a certain number of clinical test results
showing the results gotten by the apparatus of the invention.
Previously, it will be noted that, with the apparatus describes
higher, the effect of shielding is obtained until several tens of
centimetres, typically up to 3 to 4 metres of ray, thus allowing
to completely protect the user whatever his position compared to
the source of electromagnetic radiation and whatever the place
where the apparatus of the invention near this same source is
placed (this last positioning not being a critical parameter for
the obtaining of an effective shielding).
1) Posturologic study
One studied the position and the evolution with the floor of the
projection of the center of gravity of an individual placed on a
platform of clinical stabilometry standardized (for example of
type Dynatronic Don50) giving in particular an indication of the
stability of the individual and of his laterality by analysis of
the surface (stability) and the off-centring (laterality) of the
trace of the projection of the center of gravity on the
An excess of surface and/or an excessive laterality are usually
correlated with pathologies such as strabism, disorders of ocular
convergence, lumbagos, cervicalgies, sensations vertiginous, etc
On a sample of 35 persons, the posture of each individual was
analyzed pendent one duration 50 seconds: initially without
computer with proximity, then with computer placed at 70 cm but
without apparatus in accordance with the invention (situation
which one will call thereafter “nonprotected screen”), and finally
with the same computer provided with an apparatus in accordance
with the invention (“protected screen”).
It is observed that in 73,3% of the case (of including 63,5% in a
statistically significant way, i.e. introducing to a deviation of
laterality of at least E 7,1 mms), the individuals in front of the
protected screen improve their postural balance and thus eliminate
a factor of tiredness and disorders organic or psychological being
able to be bonded with the working on screen.
This study watch moreover that:
- a third of the persons having presented the aforementioned
change left/right laterality,
- 46,5% of the persons improve their balance in front of the
protected compared to the initial measuring carried out without
-40% of the individuals worsen their imbalance in laterality
when they pass from the initial situation without screen to
tion with nonprotected screen, and
- it noted forever of aggravation statistically signi
ficative of laterality because of addition of the apparatus
in accordance with the invention.
2) Immunologic study
This study, carried out on five subjects, takes into account the
respect Thelper lymphocytes/Tinducteur lymphocytes, especially the
rate CD5/CD20 which, when it increases, is an indicator of the
tendency to develop autoimmune diseases and, when it decrease,
indicates an improvement of the immune potential. A normal rate is
around 10%, a deviation between two analyses being regarded as
significant for a variation from at least stupid 15% compared to
the initial digit.
The persons all tested were users of computerised screens pendent
several hours per day.
The blood analyses were carried out as follows:
Subjects 1, 2, 3: first analysis with nonprotected screen, deuxiè
me analysis with pendent protected screen 14 days,
Subject 4: first analysis with nonprotected screen, deuxiè
me analysis with pendent protected screen 7 days,
Subject 5: first analysis with protected screen since more
of 3 months, second analysis after 14 days of
blanking of the shielding.
The results given on graphic are referred the # 1 with #5
of figure 6, respectively for the five subjects considered; the
single hatchings correspond to a situation with nonprotected
screen and the crossed hatchings, with a situation with protected
screen by the apparatus of the invention. One can see that, except
for subject N 4 for which the variation of rate CD5/CD20 is not
sufficiently significant, for the other subjects the passage of a
situation of nonprotected screen to a situation of protected
screen watch a significant improvement of the immune potential of
Inversely, in the case of the subject n0 5 the blanking of the
shielding showed a degradation of the immune potential.
3) Energetic study of medicine
In this study, one has measured, by the auriculo-cardiac reflex
according to the Nogier method, the quantitative variations of the
energetic fields, expressed in-depth of penetration, corresponding
ones to a superficial tissue, an average tissue and a deep tissue;
the respective values considered as normal are typically 6 cm, 8
cm and 10 cm, a value lower corresponding one with a degradation
of the potential of the individual.
Measuring was carried out on ten patients, successively in a
situation without screen, with nonprotected screen and protected
The results are illustrated on figures 7 (has) with (c),
respectively for a superficial tissue, an average tissue and a
The absence of hatchings corresponds to the situation without
screen, of the single hatchings correspond to a nonprotected
screen and crossed hatchings with a protected screen. The values
spans on the graphic ones are the average values of given
collected for the whole of the sample.
As one can very clearly see it with the examination of graphic of
these figures, one notes that the potential capacitances of the
individual, highly degraded by a situation of working on
nonprotected screen, are, according to case's, integrally or
nearly completely restored by the use of the device of the
4) Neurophvsiologic study
One studied the neurophysiological parameters of a sample of
patients working daily on computerised terminal.
These patients work first of all on nonprotected monitors; at the
4th day, one carries out a first neurophysiological study, at the
7th day one place the apparatus of shielding of the invention and
at the 18th day one carries out one second neurophysiological
One notes between the two observing a net improvement of the
response to the light stimulus for the sequences closed eyes/open
eyes and, especially, to the light pacings with 20 Hz, on the one
hand for the whole (0,5-31,5 Hz) of the band recorded by the
electroencephalograph, on the other hand for the bands alpha (7,5
to 13,5 Hz) and beta (13,5 to 31,5 Hz). As a whole, this increase
goes from single to the dual one.
