Are wireless phones a health threat?

As a company involved with the radiation issues associated with wireless and laser products since 1984, and just like the scientists and engineers around the world who are debating this important question, we know that wireless radiation frequencies penetrate the head and body, and increase the temperature (SAR thermal level) of the brain and other body organs while the phone is in use. Discoveries published since 1999, however, confirm it also affects protective biological mechanisms in the body far below the thermal level, and it is extremely important to recognize that none of the numerous health risks attributed to wireless phone radiation are thermally induced. See Computer Generated Images for illustrations of phone radiation entering the body.

While some have categorically stated there is no danger if phones are compliant with the SAR standards being disputed, others have referred to specific cases to illustrate the hazards and justify their conclusions. The number of phone radiation related incidents being reported and manufacturers applying for patents that include components designed to reduce the health risks clearly indicates there is a risk.

As a manufacturer of laser products, we know that laser warning labels are mandatory in many nations when the output power exceeds 1mW, and in November, 1997, the United Kingdom banned class 3a laser pointers (above 1mW) from commercial sale. Yet mobile phones, all of which have an output power hundreds of times greater than our laser products, do not require warning labels.

What health problems have been reported by wireless phone users?
Frequently symptoms and diseases reported to physicians and mobile phone manufacturers include several types of cancer, headaches, vision and hearing difficulties, increased ear and facial temperatures, nausea, dizziness, tingling sensations on the skin, and numbness or irritation to the face and neck. Some studies have presented evidence that blood pressure increases when a using a mobile phone, and there has been litigation over cancer and brain tumors allegedly caused by mobile phone radiation. Click here to see a list of more than 50 heath disorders attributed to wireless phone radiation.

Do government authorities and mobile phone manufactures say they are safe?
Regulatory agencies, phone manufacturers and manufacturers have never said they are safe, and although the FDA was the first regulatory agency to admit they did not know if wireless products are safe, it appears they actually knew otherwise. All regulatory agencies state wireless products are compliant with published safety regulations and specifications, however the specifications and associated test procedures have created many debates. These organizations continue to spend millions of dollars testing the effects of mobile phone radiation, with many studies funded by phone manufacturers.

Wireless phones are unusual because they are the only radiation producing consumer product that people intentionally place against their head and body for an extended amount of time. Since adequate testing and research typically requires years to complete, the rapidly changing technology makes it impossible for these organizations to publish their findings before the products being tested become obsolete. Moreover, there is no test equipment available that can measure the effects of radiation frequencies upon the body, including those generated by pulsed frequency modulation schemes incorporated into newer technologies.

We contacted many mobile phone manufacturers for information about the radiation levels and overall safety of their products. The responses from those that responded were similar to the one presented below, which was received from an American manufacturer on March 17, 1998. The manufacturers name (xxx), model number (yyy), specifications (zzz) and sales information are omitted.

"Thank you for you inquiry regarding xxx's zzz digital subscriber products. The current zzz MHz yyy phone operates at zzz mW.

Your wireless telephone is a radio transmitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) energy. When you use your phone, the system handling your call controls the power level at which the phone transmits.

Exposure to Radio Frequency  Energy: In 1991, the Institute of Electrical and Electronics Engineers (IEEE), and in 1992 the American National Standards Institute (ANSI), updated the 1982 ANSI standard for safety levels with respect to human exposure to RF energy. Over 120 scientists, engineers and physicians from universities, government health agencies and industry, after reviewing the available body of research, developed this updated standard. In March, 1993, the U.S. Federal Communications Commission (FCC) proposed the adoption of this updated standard.

The design of xxx wireless phones comply with this updated standard. Of course, if you want to limit RF exposure even further than the updated ANSI standard, you may choose to control the duration of your calls and operate your phone in the most power efficient manner possible.

Should you have any questions about our phones used in conjunction with any personal medical devices such as pacemakers, hearing aids, etc.), please consult the manufacturer of those devices to determine if they are adequately shielded from external RF energy."

What is SAR and SAR testing?
Regulatory agencies have established Specific Absorption Rate (SAR) guidelines, standards and test procedures to define radiation levels that can be safely absorbed by the body. Many of these agencies are also responsible for encouraging telecommunications industry growth.

SAR guidelines require testing distances less than 20 centimeters (approximately 7.8 inches) for compliance. SAR is measured in Watts per Kilogram (W/kg) of body mass, which represents the estimated RF absorption rate in body tissues. It varies, among other things, according to a users body size and the phones frequency. See The SAR Fallacy for information about why the

SAR tests only measure the thermal effects (heat) of radiation for a brief amount of time and probes would literally have to be inserted into the head of a person while they are using a phone to derive accurate results. For obvious reasons, SAR test results presented to the public are based upon human head models with thermal tissue simulations, computer models or by other means where the results are estimated. According to Mobile Phone News, the President of Arpel Laboratories, a well respected and leading independent SAR testing laboratory, said "the methodology is very ambiguous," and their Chairman stated "computation may provide a different outcome than real measurement because it involves simulation of the handset".

SAR test results for radiation shielding products are normally presented as a percentage of shielding effectiveness compared to the standards adopted by the FCC and other organizations. These standards remain controversial and continue to be the basis for many debates, particularly when one considers that SAR tests do not measure or otherwise consider the effects of radiation below what can be measured at the thermal level. Many mobile phones emit radiation close to the maximum approved SAR levels when used in environments without obstructions, and the radiation increases in poor reception areas. See The SAR Fallacy for additional information.

There has been considerable public disagreement about the effectiveness of SAR exposure limits and guidelines proposed by the FCC in 1993 and adopted in 1996. These guidelines are used to regulate phone radiation levels and incorporate many of the standards adopted by the Institute of Electrical and Electronics Engineers (IEEE) in 1991, and the American National Standards Institute (ANSI) in 1992. When the proceedings were held in 1996 to review the FCC guidelines, agencies such as the FDA did not agree that the proposed guidelines "for radiated power were sufficient to guarantee compliance with SAR limits." The FDA findings were presented in a letter to the Subcommittee on Telecommunications, Trade, and Consumer Protection of the United States House of Representatives on May 5, 1997.

These considerations, combined with evidence that phone radiation affects protective biological mechanisms in the body far below what can be measured at the thermal level, clearly demonstrates that SAR test procedures do not reflect the actual effects of radiation on the human body. For these reasons, all AegisGuard Tests measure actual radiation frequencies with, and without, AegisGuard Shields installed using globally recognized ASTM (American Society of Testing and Materials) D4935-99, Mil-STD-285 and IEEE-STD-299 test standards and procedures.

What about Hands-Free headsets?
Headsets allow you to use a phone without placing it against your head, and most people attach the phone to their belt, briefcase or purse using a belt clip or other mounting device. Radiation penetrates areas such as the liver, kidneys, waist, groin and hip when using a belt clip and enters the ear canal directly from the headset. 

The media published studies in 1998 advising that pregnant women should not use cellular phones because of the risk to unborn embryos. During May, 1999, similar reports were released citing increased risks for men and women who use hands-free kits. These reports addressed concerns about the radiation emitted by the wire between the phone and headset, and emissions from the earpiece directly into the ear canal. Wireless headsets use a technology that replaces the headset wire with an additional transmitter and receiver and may prove to represent a greater health risk than wireless phones.

In July, 1999, the London Sunday Mirror published the results of a study they commissioned about hands free kits, and a new element was added to the phone radiation controversy. The study revealed phones operate at higher power levels when they are held lower than the head, thus generating more radiation. Tests performed on a dummy torso filled with chemicals designed to imitate the human body displayed areas surrounding the liver and kidneys being flooded with energy. 

During December, 2000, the British government distributed leaflets throughout the United Kingdom addressing the health risks of mobile phone radiation and reversed their health approval  recommendation advising consumers to use hands-free headsets after a number of investigations revealed they channeled radiation into the head. The headset recommendation reversal occurred after the British government commissioned SAR tests showing headsets reduce radiation and provided credence to the debate over SAR standards and test procedures being flawed.

Does cell phone radiation exposure increase in an automobile?
Yes. Studies have demonstrated the cocoon-like, metal structure of an automobile increases radiation exposure when the phone's circuitry increases its signal strength to compensate for poor reception, and that the metal structure reflects radiation, creating a 'ricochet' effect. Some automobile manufacturers now include warnings in their instruction manuals that cell phone users should add an external antenna, however this may be more out of concern about interference with the vehicles electronic systems.

One of the greatest dangers in an automobile is when a driver pays more attention to the phone than their driving. Many nations require hands-free car kits for mobile phone usage in automobiles, and it expected that other countries will pass similar legislation over the next few years. Ironically, headsets can be more dangerous than using a phone.

Are other people exposed to radiation from my wireless product?
A person within 3 inches (7 centimeters) from you is exposed to the same amount of radiation emitted by your wireless product that you are. Although the amount of exposure significantly declines over distance and a 12 inch (30.48 centimeter) distance is considered safe by some scientists, it is impossible to avoid radiation frequencies in the air that surrounds all of us or reflected off surfaces within close proximity to wireless products,

Are all cell phones, and other wireless products and networks, including IoT, a health risk??
Yes. The proliferation of wireless devices, and their networks, increasing at a rapid rate has resulted in a corresponding increase of reported adverse health effects, particularly among individuals who are electrosensitive (
IEI-EMF, EHS, and ES)

Do radiation levels vary between different parts of a cellular phone?
Radiation frequencies are emitted from the entire phone, with the highest level being generated by the radio system (transmitter and receiver), the internal antenna system, the earpiece, display and keypad. This is why shielding devices that are designed to cover only a small portion of the phone are ineffective. Click here for additional information.

What should I consider when buying a radiation shield?
The World Health Organization says you should not use shielding products that claim to absorb radiation. This includes conductive products, products containing metal, such as silver, gold, copper, nickel, etc., or any product that requires grounding. AegisGuard Radiation Shields are the only personal shielding products that deflect radiation frequencies
away from the body at an angle opposite of the originating source. Click here for additional information.

Carefully review the test results and claims made by the manufacturer or supplier, paying attention to the frequencies tested and the duration of the tests. Most claim to absorb radiation and present SAR or other short duration test results performed using lower frequency phones than those currently sold in most nations. You will also discover most other shielding products are ineffective at frequencies below 50 Hz. or above 1 GHz. Most phones operating in Europe, Asia and the United States operate at frequencies above 1 GHz.

Shielding products covering one part of a wireless product, such as the screen, speaker, ear piece, etc., offer little, if any, protection. An effective shielding product must deflect radiation frequencies away from the user. Click here for additional information.

Products including pendants and chips claim to provide magnetic field shielding benefits using a variety of techniques, however magnetic fields have not been linked to the health effects associated with the cellular phones. Click here for additional information.

Some companies claim their shielding products improve reception. Many scientists believe the few shielding products that might improve reception actually do more harm than good, because the phone, or other wireless product, must increase its signal strength and corresponding power output to compensate. This is easily confirmed by noting the increased battery consumption when using these types of products. Click here for additional information.
