Grave Cell Phone Dangers Revealed

“Though intended for renovations, Chris Anderson would like all visitors to deposit their cellular phones in the cement mixer by his front door. This sounds excessive – until you step into Anderson’s orchard, where the pegged needle of a shrieking electromagnetic radiation (EMR) meter placed beside a connected cellphone still shows significant exposure 100 feet away.”

“Much to the chagrin of this certified EMR-mitigation specialist, every day some 300 million cell phone users are “reaching out and touching someone you love. Yourself, and anyone else within range of the microwaves emitted by your cell phone.”

“Mesmerized by magical gadgets, we have yet to count the costs of miniature radio transmitters that are transforming Marconi’s invention into new possibilities for portable personal pollution. As entire nations reach for pocket communicators, the explosively emergent $40 billion a year cell phone industry is poised to deliver a “Wireless Revolution” which, over the next five years, is expected to double the one-billion people connected by telephone lines over the past century.”

“Silicon sensors are already calling to each other. Soon, countless communicating microchips embedded in everything from bumpers to brooms will be sending streams of encoded electrical energy through glass, steel, concrete, bone and flesh. Exquisitely sensitive to subtle electromagnetic harmonies, human brains and bodies as intricate as galaxies depend on tiny electrical impulses to conduct complex life-processes – including the ability to read, recall and respond to these words. Acting as antennas, our anatomies just as easily tune into spurious signals from radio and microwave transmissions. Blake Levitt, author of Electromagnetic Fields, says that when it comes to cellphones, “a worse frequency could not have been chosen for the human anatomy.”

“As cell phones conquer consumer minds and markets, researcher Carolanne Patton notes that “the brain reaches peak absorption in the UHF bands, right where cellular telecommunications operate.” British military scientists have discovered that cellphone transmissions disrupt the brain sites for memory and learning, causing forgetfulness and sudden confusion.”
….”Instead of just another dangerous distraction, tests conducted by the U.S.Department of Energy found that using a cell phone severely impairs memory and reaction times. “Hands-free” mobile speaker-phones cause even more crashes because they typically emit 10-times more brainwave interference than handheld units.”….In New Zealand, cellphone towers are prohibited on school property because of possible health effects. But Health Canada regulations ignore the hidden hazards of cell-wrenching cellphones, which send pulsed signals through the skull in a process one expert likens to “jackhammers on the brain.” “Safety Code 6″ looks only at microwaves burning skin.” “Basically, Health Canada claims if it can’t cook you, it can’t hurt you,” says Walter McGinnis. “It’s like saying cigarettes aren’t dangerous unless they burn you.”

“One of a handful of licensed electricians who understand electromagnetic fields well enough to eliminate them from household wiring, McGinnis has been testing EMFs and collaborating with fellow testers and researchers for nearly a decade. In Victoria, where he has helped residents defeat six cellphone towers, there was dancing in the streets after Microcell Connexions withdrew its application to erect a microwave transmission tower against the Wishart Elementary School fence in the spring of 1998. Microcell spokesman Colin McCrae points out that emissions from the company’s towers carry about the same energy as a 50-watt lightbulb – well within federal guidelines.”

“This is hardly reassuring, retorts the former president of the Wisehart parents advisory council. Tania Berenuik observes that Health Canada “also told us thalidomide, asbestos and the blood supply were safe.” Carrying similar risks of long-term lethality, and strangely just as legal, cellphone addiction mirrors the prestigious early allure of smoking – as well as an immensely profitable industry’s steadfast denial of risk and responsibility. As poisonous as cigarette smoke and even harder to corral, the cellphone’s “second-hand” microwave and to bystanders – particularly children riding in cars that transmit amplified cellphone signals through their steel structure. Reporting the conclusions of a 12-person British study team, scientist Sir William Stewart told London’s Financial Times that “children may be more vulnerable because of their developing nervous system, the greater absorption of energy in the tissues of the head and a longer lifetime of exposure.”

“Roger Coghill became a long-standing advocate for health warnings to be affixed to cell phones after this biologist found that cellphone transmissions damage the ability of white blood cells to ward off infectious disease by disrupting the immune system’s electromagnetic communications. Dr. Neil Cherry has measured accelerated aging, increased cell death and cancers caused by radio frequency microwaves from cellphones and their relay towers. With the brain’s electro-chemical communications repeatedly zapped by lightning-like cellphone pulses, this Ph.D. biophysicist warns that headaches, fatigue, lethargy, nausea, dizziness, depression, arteriosclerosis and even Alzheimer’s can result from frequent or prolonged calls on cell phones.”

“There is also a higher incidence of cardiac problems,” Cherry comments, “in terms of the timing function in hearts. You get more heart attacks and more heart disease – it has now been shown in many studies.” The biophysicist from Lincoln University in Christ Church, New Zealand has also found that cell phones can murderously modify moods. In brains and bodies seriously derailed by tiny imbalances in trace minerals and hormones, depression, suicide, anger, rage and violence can result when calcium and serotonin levels are disrupted by cellphone transmissions.”

“In 1995, Cell phone sales in North America exceeded the birth rate. Hired by the Cellular Telecommunications Industry Association to condone cellphones, public health scientist George Carlo found that rare tumors on the outside of the brain are more than doubled among cell phone callers – particularly on the right side of the head where phones are usually held. Carlo told ABC’s “20/20” that cell phone causes genetic damage that leads to cancer. Warning of “the potential for a global health disaster,” ABC recommended “prudent avoidance” of cellphones after finding that every cellphone they lab-tested exceeded the Federal Communication Commission’s standards for EMF absorption rates. EMF researcher Dave Ashton cautioned 20/20 viewers that because cellphones constantly search for the nearest repeating tower, “long-term damage comes from cell phones in the stand-by mode.” Cell phone “shields” and headsets “cannot adequately address these problems,” Ashton added.”

“Dr. Carlo later told London’s Express newspaper that cellphones cause genetic damage following a dose-response curve. That is, the more a person uses a cell phone, the more cellular destruction and health risks they incur. Cell phone-confused cells can go crazy, Carlo cautioned. Experiments on captive animals show that this cumulative DNA damage is passed on to succeeding generations.”

“Addicted as we are to a culture of convenience, we forget how inconvenient it is to contract cancer. An Adelaide Hospital study confirmed Carlo’s conclusions after finding B-cell lymphomas doubled in mice within 18 months of one-hour daily exposure to power densities experienced by a cellphone user. B-cell lymphomas are implicated in 85% of all cancers.”

“Ready or Not As magazine-size “cellular” relay antennas hidden in church steeples and rooflines keep popping up just about everywhere, more and more communities are declaring their airspace a “No Fry Zone”. But in Canada, where cell phone towers come under federal jurisdiction, municipalities are only “advisers’ to a process in which no permits are required to erect transmitter towers deemed necessary for “national security.” Cellphones do save a lot of lives. FCC Chairman William Kennard reports that every day more than 98,000 people make 911 calls from wireless cell phones.”

“Many more lives are involuntarily imperiled by non-emergency calls. Pat Irwin was working in a Colwood health food store when she noticed a truck unloading metal framework. The next morning, a new cellphone tower was ready to add its emissions to another BC Tel tower already operating down the street. There had been no announcement, no public hearings – just a quiet notification to the municipality that a tower was going up, literally overnight.”

“The intruder radiated for a month when Irwin felt her immunity dropping. She wondered if other changes in her energy and menstrual cycle were “not from the moon or something that I ate.”

“Irwin also seemed more irritable after her central nervous switchboard began receiving round-the-clock cellphone calls. With cellular relay towers in Kansas and Oklahoma being shut down because they interfered with passing aircraft, Irwin sensed how the same transmissions plucked her own electrical circuitry, inflicting a “chronic edginess” that “twangs human nerves.” Sleep disorders, she learned, are common among people exposed to high levels of electromagnetic pollution.”

“After several other women in the same business centre reported similar symptoms, Irwin quit her job. “I saw it as something that was there to stay and I’d be daily exposed to it over a long period of time,” she told Alive. “All this stuff is what we’re playing with on a daily basis, and we don’t know the long-term health effects.”

“Implying recognized hazard, cell phone companies such as B.C.’s FIDO insist that the new digital phones operating at 1/50 the power of older analog models are safer. But there is nothing “safe” about the new 1.9 gigahertz broadcasting frequency. Much like a boxer taking repeated blows to the head, rapidly pulsing cellphones signal permanent brain damage. A study by Dr. Peter Franch found unequivocally that “cells are permanently damaged by cellular phone frequencies.” This cellular damage, Franch noted, is maximized at low dosage – and “inherited unchanged, from generation to generation.”

“Attempting to explain a 25% increase in asthma and a 5% increase in asthma-related death rates throughout rapidly “mobilizing” metropolitan Sydney, Franch found that the production of histamine, which triggers bronchial spasms, is nearly doubled after exposure to mobile phone transmissions. Cellphones also reduce the effectiveness of anti-asthmatic drugs, and retard recovery from illness.”

“Katharina Gustavss, a certified Building Biology consultant with 25 years experience, explains that CDMA’s 217 Hz spikes are very close to the frequencies of human cell membranes. Gustavss accompanied a Microcell technician to the Colwood microwave relay tower Irwin and others had complained about. When he waved a spectrum analyzer, Gustavss checked the display and saw “pretty scary” energy spikes. “What’s that?” she asked the tech. “I’ve never seen that before,” he told her. It turned out that this cellphone tower tester only set his meter to an averaging mode. Switching to “real time” froze the readings at “scary” maximum output levels.”

“How dangerous are cell phones? “The risk is extremely high,” declares Dr. Cherry. “There are 66 epidemiological studies showing that electromagnetic radiation across the spectrum increaseS brain tumors in human populations. Two of those studies are for particular brain tumors from cell phones.”

“Cherry says that because cancer takes decades to develop, it will be another 10 or 20 years before “mobiles” manifest a big bonanza in brain tumors. But he adds, we’re already seeing “acute effects that are noticed within minutes of using a cell phone.”

“After two minutes’ conversation, a cell phone’s digitized impulses disable the safety barrier that isolates the brain from destructive proteins and poisons in the blood. Professor Leif Salford, the neurologist who carried out the research for this finding, informed the Daily Mail: “It seems that molecules such as proteins and toxins can pass out of the blood, while the phone is switched on, and enter the brain. We need to bear in mind diseases such as MS and Alzheimer’s which are linked to proteins being found in the brain.”

“Dancing with the Telecomonster If you must pack a cell phone, treat it like a loaded pistol. Keep it turned off. Don’t carry it near ovaries, testicles, or the heart. For partial protection, buy an antenna shield. Limit calls to one-minute, six to 10 minutes a month. Never fire off a cellphone with children anywhere in sight.”

“A better bet is to facilitate the growth of organic telephone networks with lots of fibre. Instead of more microwave towers, “We should be wiring up our cities with fibre-optic cables to provide Internet, fax, telephone, radio and television at very high quality,” Cherry urges, “rather than saturating our cities with the microwave, radiowave and low frequency signals all the time.”

“When it comes to cells, consciousness and cell phones, every call is collect. How can convenience count more than cancer? What is gained by being in constant contact with disembodied voices, while being “out of touch” with the friends and neighbours around us? Are we comfortable having our location traced by monitoring authorities?”

“Unless we start voting with our wallets, consumer complacency could prove as species-limiting as corporate cynicism. “Microwave frequencies are the same as those used in radar and your microwave oven,” says Florida cellphone tower opponent Joe Chwick. “You wouldn’t think of sticking your head in the oven, but there is no hesitation to putting the cell phone to your ear.”

Definitions

The properties and effects of non-ionising radiations are very diverse. For the purpose of this Policy non-ionising radiations include:

Extremely low frequency (ELF) radiation

Electromagnetic radiation with frequencies in the range 0 Hz (static fields) to 3 kHz, including the 50 Hz electric and magnetic fields associated with the domestic mains electricity supply such as in domestic electrical appliances, electricity supply substations and overhead power lines.

Radiofrequency (RF) radiation

Electromagnetic radiation with frequencies in the range 3 kHz to 300 GHz, which is produced by artificial sources such as visual display units and mobile phones.

Microwave (MW) radiation

Electromagnetic radiation with frequencies in the range 1 GHz to 300 GHz, which is produced by artificial sources such as in microwave ovens and by microwave communication devices. (This radiation is now considered part of Radiofrequency radiation.)

Infrared (IR) radiation

Electromagnetic radiation with wavelengths between 700 nm and 1 mm, which is present in sunlight and produced by artificial sources such as electric radiator heaters.

Visible light

Electromagnetic radiation with wavelengths between 400 nm (blue) and 700 nm (red), which is present in sunlight and produced by numerous artificial sources, including lasers.

Ultraviolet (UV) radiation

Electromagnetic radiation with wavelengths between 100 nm and 400 nm, which is present in sunlight as well as produced by artificial sources such as arc welding and sterilization lamps.

Electric fields

Magnetic fields

  1. Electric fields arise from voltage.
  2. Their strength is measured in Volts per metre (V/m)
  3. An electric field can be present even when a device is switched off.
  4. Field strength decreases with distance from the source.
  5. Most building materials shield electric fields to some extent.
  1. Magnetic fields arise from current flows.
  2. Their strength is measured in amperes per meter (A/m). Commonly, EMF investigators use a related measure, flux density (in microtesla (µT) or millitesla (mT) instead.
  3. Magnetic fields exist as soon as a device is switched on and current flows.
  4. Field strength decreases with distance from the source.
  5. Magnetic fields are not attenuated by most mat

“Mobile telephones, television and radio transmitters and radar produce RF fields. These fields are used to transmit information over long distances and form the basis of telecommunications as well as radio and television broadcasting all over the world. Microwaves are RF fields at high frequencies in the GHz range. In microwaves ovens, we use them to quickly heat food.””At radio frequencies, electric and magnetic fields are closely interrelated and we typically measure their levels as power densities in watts per square metre (W/m2).”

“Key points:

  • The electromagnetic spectrum encompasses both natural and human-made sources of electromagnetic fields.
  • Frequency and wavelength characterise an electromagnetic field. In an electromagnetic wave, these two characteristics are directly related to each other: the higher the frequency the shorter the wavelength.
  • Ionizing radiation such as X-ray and gamma-rays consists of photons which carry sufficient energy to break molecular bonds. Photons of electromagnetic waves at power and radio frequencies have much lower energy that do not have this ability.
  • Electric fields exist whenever charge is present and are measured in volts per metre (V/m). Magnetic fields arise from current flow. Their flux densities are measured in microtesla (µT) or millitesla (mT).
  • At radio and microwave frequencies, electric and magnetic fields are considered together as the two components of an electromagnetic wave. Power density, measured in watts per square metre (W/m2), describes the intensity of these fields.
  • Low frequency and high frequency electromagnetic waves affect the human body in different ways.
  • Electrical power supplies and appliances are the most common sources of low frequency electric and magnetic fields in our living environment. Everyday sources of radiofrequency electromagnetic fields are telecommunications, broadcasting antennas and microwave ovens.”

“The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy (or equivalently, by virtue of the relations in the previous section, according to frequency or wavelength).”

Regions of the Electromagnetic Spectrum

“The following table gives approximate wavelengths, frequencies, and energies for selected regions of the electromagnetic spectrum.”

Spectrum of Electromagnetic Radiation


The notation “eV” stands for electron-volts, a common unit of energy measure in atomic physics. A graphical representation of the electromagnetic spectrum is shown in the figure below.

The electromagnetic spectrum


“Thus we see that visible light and gamma rays and microwaves are really the same things. They are all electromagnetic radiation; they just differ in their wavelengths.”

The Spectrum of Visible Light

The visible part of the spectrum may be further subdivided according to color, with red at the long wavelength end and violet at the short wavelength end, as illustrated (schematically) in the following figure.

“The sampling rate, sample rate, or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal. For time-domain signals, it can be measured in hertz (Hz). The inverse of the sampling frequency is the sampling period or sampling interval, which is the time between samples.”
