Cell Phones -
More Damning Evidence

Preventive Psychiatry E-Newsletter #66

"Neither radiofrequency (30kHz-300MHz) nor microwave fields (300-3000 MHz) exist as significant components of the natural terrestrial electromagnetic environment. In consequence, our human generation is the first to voluntarily expose itself to artificial RF/microwave fields
that cover a wide spectrum of frequencies and intensities.
Typical mobile phones radiate an average power of 0.2-0.6 W. When hand-held and operated close to the head, background levels are sharply distorted, with 40 percent of radiated phone energy absorbed in the hand and the head ([Kuster et al., 1997]). In this mode of operation, a mobile phone may be regarded as a quite powerful radio transmitter. Its emission at the head surface is typically 10,000 times stronger than fields reaching the head of a user standing within 30m of the base of a typical mobile phone relay transponder mounted on a tower 30m above ground." W. Ross Adey, International Encyclopedia of Neuroscience
What is the effect of the radiation?
While industry sponsored studies have failed to show a clear link between cell phone usage and brain tumors (there are other effects which have been ignored by industry studies), independent scientific studies show that the radiation from hand held mobile phones do pose serious health risks and can increase the incidence of brain tumors. Microwave signals travel through human tissue, glass, metal and plastic. Human tissue also absorbs microwave radiation. The effect of even minute levels of microwave radiation have been shown to:
* open the blood-brain barrier
* heat head & brain tissue
* disrupt brain activity
* reverse cell membrane polarity
* alter brain waves
* alter brain chemistry
* damage DNA
The effects of the radiation can produce a wide range of physical symptoms. Some symptoms may take years to show up. Some of the effects can be short-term while other effects can be long-term or permanent. Opening the blood-brain barrier allows toxins into the brain that cause
a wide range of ailments - many of which are currently unknown or poorly understood. Some symptoms of cell phone usage:
* headaches
* memory loss
* mood swings (rage)
* fatigue
* loss of concentration
* lack of coordination
* pain in hands or arms
* nausea
* sleep disorders
The Evidence
If you use a cell phone you could be at serious risk for delibitating and life threatening illness. Following are just a few of the studies that document the risks associated with exposure to the radiation from cell phones:
Cell Tower Radiation Shown to Cause Headaches and Nausea
Three Dutch ministries recently conducted a study that found that the radiation from the next generation cell phone towers can cause headaches and nausea. The study is the first of its kind and compared the impact of radiation from base stations used for the current mobile telephone network with that of cell towers for new third generation (3G) networks. The study used lower a dose of radiation than cell phones. Hand held phones emit stronger radiation when they are used, while cell towers transmit more constant levels of radio signals, exposing everyone within range.
"If the test group was exposed to third generation base station signals there was a significant impact... They felt tingling sensations, got headaches and felt nauseous," a spokeswoman for the Dutch Economics Ministry said.
Cell Phone Radiation Opens the Blood-Brain Barrier
A study headed by Leif Salford, Department of Neurosurgery at Lund University in Sweden and published in Environmental Health Perspectives suggests cell phone use can damage neurons in the brain. A number of studies have looked at potential links between cell phone use and cancer, most finding little or no effects. This study found that exposure to electromagnetic fields emitted by certain phones was associated with the leakage of albumin through the blood-brain barrier and neuronal damage that increased in response to the amount of exposure. While the study sample was small, researchers said the combined results are "highly significant and exhibit a clear dose-response relation."
The Head Absorbs Radiation
Headaches, nausea, dizziness, short-term memory problems, fatigue, and other complaints resulting from cellular phone use are not due to low-level heating of the brain; instead, they're apparently caused by the head serving as an "antenna" and brain tissue as a radio receiver, according to two Jerusalem researchers. Zvi Weinberger, a physicist who heads the applied physics department at the Jerusalem College of Technology, and Dr. Elihu Richter, head of the occupational medicine unit at the Hebrew University-Hadassah Braun School of Public Health, suggested this in the latest issue of the journal Medical Hypotheses. Mobile phones, they explained, "broadcast specifically at frequencies at which the head serves as an antenna and brain tissue serves as a demodulating radio receiver." Thus, precaution must be taken in the use of cell phones, they wrote. Jeruselem Post 12/02/02
Mobile Phone Signals Affect Brain Activity
A study reported in the Journal of Sleep Research (Blackwell Publishing) found that 30 minutes exposure to electromagnetic fields, as from GSM mobile phones, caused changes to brain activity which lasted long afterwards. Dr Peter Achermann and colleagues from the University of Zurich, and ITIS, in Zurich, found that blood flow increased in areas of the brain on the side nearest the phone, and that this effect lasted for over half an hour afterwards. They also discovered that the brain?s electrical activity (?brain waves?) was not only affected immediately after the exposure, but that this lasted through much of the subsequent night?s sleep.
Radiation From Cell Phones Can Make Cancer Grow Faster
"Italian scientists have raised new health concerns about the safety of using mobile phones, with research showing radio waves from the handsets makes cancerous cells grow more aggressively.." Reuters, 10/23/02
Cell Phone Radiation Can Cause Brain Tumors
An epidemiology study conducted by Dr. Lennart Hardell found a higher incidence of brain tumors on the sides of heads used by mobile-phone subscribers to make and receive calls. The study was published in the August, 2002 issue of the European Journal of Cancer Prevention.
The body of evidence showing the hazards of cell phones is more than sufficient to cause alarm, yet, public health organizations continue to stall while the cell phone industry builds more towers and makes Billions selling more phones. Just as the tobacco industry was able to hold back the truth regarding the health effects of smoking, the cell phone industry has prevented the truth about cell phone safety from reaching mass media. If you care about your health and the health of your family, take the time to educate yourself and have the courage to act on what you find.
What you can do to reduce your risk:
* Simply don't use a cell phone or stand close to someone who is. Humans have survived up to this point without them. We can continue to survive without them.
* If you must use a cell phone use it only in places with a strong signal. This allows the phone to transmit at low power (up to 100 times lower than its maximum value), reducing exposure accordingly.
* Minimize the length of calls.
* Extend the antenna and hold it away from the head. Hold the phone away from your head whenever possible.
* Use a hands-free kit with an external antenna and keep the phone away from your body.
* Do not use an earphone unless it is one made of fiber optic cable. Studies have shown that a metal earphone wire can act as an antenna and direct radiation into the head from the ear canal.
