For Your Safety |

|
There are many radiation shielding products to choose from and it can be confusing trying to understand if any are effective. It can also be dangerous if you select the wrong product for protection. It
make sense to protect yourself by using #1 doctor recommended
AegisGuard™ LS Radiation Shields,
the same personal protection radiation shields use worldwide since 2006 for
hundreds of Shielding Applications by the military,
industry,
hospitals, and individuals suffering from the effects of
electrosensitivity. |
Safety Standards And Tests |
SAR Safety Standards Think about the following paragraphs when considering low SAR phones or shielding products tested using SAR thermal measuring procedures or test instruments, and you will understand why Aegis was the first company to publicly announce that thermal measurements (SAR) should not be used as the criteria for determining radiation safety. Aegis is also the only manufacturer of radiation frequency shielding products that deflect, or reflect, the frequencies away from the body at an angle opposite of the originating source, and the only products tested at actual radiation frequency levels for extended time periods. Click here for additional SAR information. SAR safety standards are used to determine the "estimated safe levels" of cell phone and other radiation that a person can be theoretically exposed to without harm. The standards accepted and referenced by the U.S. FCC and other regulatory agencies worldwide are based upon the results of a study conducted by the United States Air Force Research Laboratory (AFRL) in 1986. Simply stated, the
scientific methods used by AFRL to define "estimated safe" temperature (thermal)
absorption rates for body organs exposed to cellular phone radiation
frequencies are based upon measuring the rectal temperature of an adult
male positioned in direct sunlight for 30 to 60 minutes. You can download the
study in pdf format (5.8 MB) by clicking

information, or concentrate on Chapter 10 to learn how the current SAR
safe thermal standards were determined. |
Product and Structure Shielding |
Shield Testing 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. AegisGuard™shielding tests are conducted by Aegis and three independent testing laboratories using products, homes and offices for the amount of time they are used by people and businesses. Each AegisGuard™ LS shielded handheld and body worn product is tested for at least 8 continuous hours, washable clothing and fabrics shielded with AegisGuard™ LL for 24 hours, and homes and offices shielded with AegisGuard™ LP for 1 year. SAR safety standard deficiencies are why AegisGuard™ Radiation Shields are tested measuring actual radiation frequencies using globally accepted testing standards and procedures, instead of temperature (SAR). Frequencies between 5 Hz. to 2.6 GHz. at power levels between 1 milliwatt (0.001 Watt) and 25 Watts are tested using ASTM D4935-99 procedures, Higher frequency tests between 5 Hz. to 1.1 THz. are conducted using MIL-STD-285, IEEE-STD-299, MIL-STD 285, IEEE 802.11 (current & proposed), and ETSI EN 302 567 standards. If standards do not exist, CPE (Customer Premises Equipment), PSG vector signal generators, and network analyzers With millimeter-wave controllers and frequency extenders are used. Deflection Versus Absorption Technologies Pendants, Chips And Other
Magnetic Field Shields 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 EMF they may possible address is magnetic fields, rather than radiofrequency RF, electric fields or near field wireless operating frequency radiation which has been linked to more than fifty adverse health effects attributed to wireless exposure from antennas, networks and devices. Click here for additional information about magnetic fields. 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 frequency emissions. Small Adhesive Phone Speaker Shields
Antenna
Shields And Signal Boosters Any device (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. These 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.

Pocket,
Pouch And Purse Shields Excluding AegisGuard™ LS and XP Radiation 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.

Headset Shielding |
Air Tube
Headsets
Ferrites
Ferrites are not designed, or intended, to be
near the body and are never used for shielding people because their electromagnetic absorption properties are
significantly affected by environmental and operating conditions,
including
temperature, pressure, field strength, frequency and time. They
do not provide any protection whatsoever from cellular phone radiation when using a
headset because they can only prevent radiation frequencies between 1 KHz. to
1 GHz. from entering the
wire, thus having no effect upon the frequencies traveling up the wire from
a cellular
phone.
