Description
THE PATENT APPLICATION OF
JOHN CHARLES MERTZ AND D. DANE DONOHUE FOR
ELECTROMAGNETIC RADIATION SHIELDING APPARATUS FIELD OF THE INVENTION
The invention of this disclosure relates to the field of
electromagnetic wave radiation, specifically energy in the microwave
region of the electromagnetic spectrum, and the possibly dangerous
effects upon the health of human beings exposed to the radiation, a
process called irradiation.
BACKGROUND OF THE INVENTION
The present invention pertains to an electromagnetic shielding
apparatus that is dimensioned to be fitted or retrofitted to the exterior
roof or interior ceiling of a structure inhabited by human beings thereby
protecting said human beings from electromagnetic radiation from a
nearby radiation emanating component, specifically a cellular phone
transmission or relay tower.
It is well known that the popularity of cellular phones has
necessitated a proliferation of relay towers for users to enjoy reliable
service. Cellular phones are portable transceivers that rely upon
stationary reception and transmission components known as cells. The
means of wireless communication is the transmission and reception of
electromagnetic radiation usually in the 850- megahertz (Mhz) or greater
region of the electromagnetic spectrum that is known as microwave
radiation. In many applications of current cellular phone technology the
power of this signal is less than one watt to more than six watts
depending upon the location of the user and proximity to a relay tower.
Therefore, relay towers are located in populated areas and often placed
on top of or in close proximity to structures such as skyscrapers,
commercial buildings and other structures or near homes. The physical
properties of electromagnetic radiation are multi-directional, thus
enabling the user to enjoy reliable transmission and reception of the
signal.
When a relay tower is located near or, especially, on top of a
building, the inhabitants are continually exposed to the electromagnetic
radiation. This problem is so prevalent that it is now called
"electromagnetic smog". Recent studies indicate that prolonged
exposure to electromagnetic radiation causes damage to the resilient
brain blood barrier that protects the brain from toxic substances. The
effect upon the health of a human being are concentration difficulties,
sleep disorders and degradation of the immune system that can result in
cancer.
It is the objective of this invention to provide an affordable and
easily applied solution to the foregoing problem, thus protecting human
beings from needless and unwanted exposure to the potential dangers
of electromagnetic irradiation. Excellent benefits are realized for
commercial buildings, such as skyscrapers, retail establishments and
office buildings, for these structures are frequently occupied by
employees on a consistent and prolonged basis. Also, excellent benefits
are realized for educational institutions due to the extended time spent in
the buildings my administrators, instructors and students. In addition,
medical institutions realize excellent benefits due to prolonged
occupation by staff and patients.
SUMMARY OF THE INVENTION
An electromagnetic radiation shielding apparatus is disclosed that
protects human beings in structures from the possibly hazardous health
risks associated with proximity to a radiation emanating component,
such as a cellular phone transmission or relay tower. A radiation shield is
disposed between a radiation emanating component, typically on the
roof of a structure, to prevent exposure of inhabitants to emanating
radiation. The radiation shield is dimensioned to fit or be retrofitted to fit
the roof of the structure for exterior applications or uppermost ceiling for
interior applications. The shielding means effectively blocks, absorbs
and/or reflects the electromagnetic radiation. The shield means can also
be placed in building components that can be place in the building to
block the electromagnetic radiation.

DESCRIPTION OF THE INVENTION
Figure 1 teaches an elevated perspective view of the
electromagnetic radiation shielding apparatus comprising building (10)
that is occupied by human being (12) that is in close proximity to
electromagnetic radiation emanating component (14) that is attached by
a mounting means (16) to the roof (18). The radiation shield (20) is
attached with an affixing means (22) to the roof (18) thereby protecting
the human being (12) from the electromagnetic radiation (invisible)
transmitted by electromagnetic radiation emanating component (14).
Effective materials for a radiation shield 20 are substances of a
sufficient molecular structure that blocks, reflects or absorbs
electromagnetic radiation thereby substantially preventing penetration
such as steel, aluminum, nickel or other metallic substances or alloys
there of. Today there are many plastic and ceramics also have the
characteristics to be capable of blocking, repelling or absorbing
electromagnetic radiation and would be effective as radiation shielding.
Figure 2 shows a sheet of the radiation shield 20. In the preferred
embodiment this sheet of the radiation shield 20 is made of aluminum or
an alloy of aluminum and nickel. However this sheet of the radiation
shield 20 can be made of almost any metal or metallic alloy or other
substance that is of sufficient molecular structure to substantially prevent
penetration by electromagnetic radiation. Since all materials vary in the
amount of material necessary to block a given intensity of
electromagnetic radiation the thickness of the radiation shield would also
vary as to the material used. Also the amount of radiation to be blocked
would vary from one location to another and thus the thickness of the
radiation shield could vary.
The radiation shield 20 a can also be a mesh as shown in Figure
3. In this embodiment as in the previous embodiment the radiation shield
20a could be made of aluminum, steel, iron, nickel or any other metallic
substance or alloy thereof or other substance with the characteristics to
be capable of blocking, repelling or absorbing electromagnetic radiation
and would be effective as radiation shielding. This embodiment could
also be achieved through the use of perforations in the radiation shield
during the manufacturing process. This preferred embodiment is
especially advantageous for use in the attics of buildings to facilitate
aeration within the structure.
The radiation shield 20 can be sold in sheets or rolls. At the
construction site the sheets or rolls of radiation shield 20 would be
affixed to the building top and other areas that would be struck by the
electromagnetic radiation. Some forms that are possible include sheets
or rolls of the desired material and an appropriate means of affixing the
material.
In situations where a cell relay tower is located on top of a
structure, such as a skyscraper or commercial building, the radiation
shield has exterior or interior applications. The radiation shield is affixed
to the roof for the exterior application. The interior application requires
affixation to the uppermost ceiling of the structure. These applications
are ideal for retrofitting the radiation shield to existing structures. The
mean for affixing could be nails, adhesive, screws or other means known
in the art. In some structures the radiation shield 20 could be just laid on
top of flooring or insulation.
The radiation shield 20 can also be incorporated in many
components in the building industrial. The radiation shield can also be
implemented during the construction process of a structure as a roof or
ceiling substrate creating an effective shield against electromagnetic
radiation.
Figure 4 shows the radiation shield 20 incorporated into a ceiling
tile 24. The sheet of radiation shield 20 of Figure 2 or the mesh of
radiation shield 20a of Figure 3 could be affixed to the back of the ceiling
tile 24 as in Figure 4. The ceiling tile 24 then would be placed on the
building's ceiling creating an affective shield against electromagnetic
radiation.
Figure 5 illustrates the radiation shield 20a incorporated into
insulation 26 wherein the radiation shield 24a is the mesh configuration
of Figure 2. When the insulation 26 is placed in the attic of a building it
effectively creates a shield against electromagnetic radiation. Also, the
radiation shield of this embodiment could utilize perforations
implemented in the manufacturing process to facilitate aeration in the
attic of the building.
Still another embodiment is the suspension of the radiation shield
means with appropriate density within a liquid vehicle such as paint or
the like. This is taught by Figure 6 wherein an enlarged cross sectional
view shows the material of the radiation shield 20b in particulate
configuration uniformly suspended in the hardened liquid vehicle 28. A
preferred embodiment is anticipated wherein the liquid vehicle is latex
paint or the like that is easily applied to walls and ceilings of dwellings
thereby providing an effective electromagnetic radiation shielding means
for the inhabitants thereof.
Still another embodiment of this invention is in the form of a wall
covering such as wallpaper. This is demonstrated by Figure 7 wherein
the radiation shield 20 with ornamental decoration 30 is applied to a
building wall 32 with a common affixations means (not shown) such as
adhesive, tacks or the like. Therefore, an effective electromagnetic
radiation shielding means is provided.
Changes and modifications in the specifically described
embodiments can be carried out without departing from the scope of the
invention, which is intended to be, limited only by the scope of the
appending claims.
