Don't be misled when reviewing shielding effectiveness claims,
particularly when a product's test results are presented as a SAR thermal
reduction based upon tests using equipment or low cost meters designed to
measure temperature (you can easily determine this if the test results are
expressed as mW/cm2). Equally as important, find out how long the tests
lasted, the number of products tested and if the products were tested at frequencies above 1 GHz.
LS 5Hz. to 30 GHz. shielding tests were conducted by three independent testing
laboratories. More than
50 products, including
multiple cell phones and other wired and wireless products. Each product
was tested in house, and by 3 different testing laboratories, for 8 hours, instead of a few seconds or minutes
like other shielding products. If you are
considering a shielding product, this is an extremely important
consideration, as is confirming that a shielding product was actually
tested at the frequency and power level of your wireless product. For
Headset and XP Radiation Shields are the only
radiation frequency shielding products for
cellular and cordless phones tested at frequencies and power levels at,
above and below what is required for wireless communication.
SAR safety standard deficiencies are
why AegisGuard™ Radiation Shields were, and continue to be, tested measuring actual radiation
frequency emissions using multiple test procedures, instead of temperature (SAR).
For frequencies between 5 Hz. to 2.6 GHz. and power levels from 1 milliwatt (0.001 Watt) and 25 Watts,
globally accepted ASTM D4935-99 procedures were used by the independent
testing laboratories. This frequency range was also included for higher frequency
tests at the identical power levels in house, the
3 independent laboratories, and are the same tests used by cell phone
manufacturers and carries.

Deflection Versus Absorption Technologies
Aegis was the
first company to advise its
employees and customers about the
risks associated with using wireless radiation shielding products claiming to absorb radiation, and
Shields are still the only shielding products
available to consumers proven to deflect radiation frequencies. In 1999, the
World Health Organization advised
consumers not to use cell phone radiation shields incorporating absorption
technologies, as does every phone manufacturer. Click

Pendants, Chips And Other
Magnetic Field Shields
The foundation of the
Wireless RF Controversy is the effect of
the non-ionizing radiation frequency element of electromagnetic radiation emitted by
these products upon our health.
Available as chips, pendants or small adhesive devices attached to
wireless phones and other electronic devices, these products claim to
“harmonize” or “neutralize” the negative effects of electromagnetic
radiation upon the body by generating a resonant frequency which is either
permanently infused in the product or powered by the human body. A review
of the available product information clearly indicates the only
portion of electromagnetic radiation being addressed is the magnetic field, rather
than the electric field or non-ionizing
near field wireless operating frequency radiation which has been
linked to more than fifty health effects attributed to cellular phone use. Click

Stress level reduction, improved
concentration and enhanced energy are benefits these products claim to
provide and while some studies suggest altering a magnetic field using
therapy, magnets or other devices may improve how a person feels, none of these
claimed benefits any correlation with the health effects attributed to
wireless or wired products. Several studies have confirmed cellular phone
use actually improves cognitive functions and while there have been many
studies linking long term power transmission line and transformer magnetic
field exposure to diseases such as leukemia, it has never been determined if
these occurrences are due to magnetic fields or non-ionizing radiation
Small Adhesive Phone Speaker Shields
The U.S. Federal Trade Commission filed
charges on February 20, 2002 against two companies selling these types
of products, stating "the
vast majority of electromagnetic energy emitted by cellular and cordless
phones comes from parts of the phone other than the earpiece."
In May, 2003, two companies
from selling these types of products
in the United States, and it should be noted these types of products were
previously banned in many nations.

Shields And Signal Boosters
Every cellular and cordless phone manufacturer warns consumers not to
interfere with a phones antenna.
It should be noted that
AegisGuard™ LS Radiation Shields does not affect, or interfere with, an antenna's
(including flashing devices for children) designed to interfere
with an antenna will cause a phone to increase output
power and, some products including signal boosters, are a health risk.
products normally consist of one or more pieces of metal that may be
enclosed in a phone case, attached to the battery, or back of a phone. When a phone
is in use, the metal used in these products absorbs radiation and
emits a radiated field the same size as the device towards the point of
least resistance; specifically the head or body. Click

Pouch And Purse Shields
With increased frequency, reports have been published since mid 2001 addressing concerns about
low level radiation emitted from a phone's components, such as the battery
or display, which are not required for cellular communication.
support an extremely wide range of frequencies and power levels
were initially developed for a wide frequency range of military
applications and they are perfectly suited to provide protection from
operating frequencies between 5 Hz. and 45 GHz. if these concerns are
proven to be justified.
Shields, body style and personal radiation shields promoted for these applications by
other companies contain an absorbent or conductive shielding material
which is not designed by the manufacturers to protect against cell phone
radiation, particularly at frequencies above 1 GHz. Click
