Is your health on the line?

Mounting scientific evidence suggests that non-thermal radio frequency radiation (RF)—the invisible energy waves that connect cellphones to cell towers, and power numerous other everyday items—can damage our immune systems and alter our cellular make-up.

Unless you’ve had your cellphone permanently glued to your ear, chances are you've heard the recent health buzz: Mobile devices may cause cancer. While it’s true that the National Cancer Institute has ruled them safe, a growing number of independent researchers disagree. Those experts point out that the FCC wireless regulations on cellphone safety are largely based on something called specific absorption rate (SAR) levels, or the rate at which our bodies absorb radiation.

Most phones do comply with the federal standards, but SAR monitors only thermal effects. In other words, if the radiation from your phone isn’t cooking your brain, it’s regarded as safe. But mounting scientific evidence suggests that non-thermal radio frequency radiation (RF)—the invisible energy waves that connect cell phones to cell towers, and power numerous other everyday items—can damage our immune systems and alter our cellular makeup, even at intensities considered safe by the FCC.

Is your body giving off important clues about your health?
“The problem is that RF can transfer energy waves into your body and disrupt its normal functioning,” explains Cindy Sage, an environmental consultant in Santa Barbara, California, who has studied radiation for 28 years.

“Here’s why that's crucial. Overwhelming evidence shows that RF can cause DNA damage, and DNA damage is a necessary precursor to cancer.” The 2010 Interphone study, the largest to date on RF exposure from mobile phones, has spawned a quagmire of controversy, says health researcher and medical writer Kerry Crofton, PhD, who spent four years reviewing RF science for her book Wireless Radiation Rescue: Safeguarding Your Family from the Risks of Electro-Pollution.

Many groups, including the National Cancer Institute and the telecom industry, read the results of that study as a green light for wireless calling. Others, like Crofton, point out that because it was largely based on lower cellphone usage in the 90s, the research has little bearing on today’s world, in which billions of people worldwide have mobile phones, most of which are “wired” all the time and sleep with their cellphones next to their heads.

One thing the Interphone study did find? People who chatted via cell for just 30 minutes a day for ten years, saw their risk of glioma (the type of brain tumor that killed Ted Kennedy) rise 40 per cent. As a result, many European countries are considering banning cellphones for children under age six (RF penetrates little kids’ brains more easily), and France has already banned all wireless technology in some schools and many public places, notes physician and epidemiologist Samuel Milham, MD, a leader in the growing field of electromagnetic research.

All parties agree on this but more studies need to be done. In the meantime, it’s best to take easy precautions—and not just with mobile phones. You’re surrounded by electronics at home and work. But you can avoid this number one health enemy.

Cellphones

When your phone is on (which it probably is even as you read this), it’s constantly sending and receiving RF signals to and from the nearest cell tower to keep you in service. The farther you are from a tower, the harder your phone has to work and the more RF it emits, explains David Carpenter, MD, director of the Institute for Health and Environment at the University at Albany. The activity really amps up when you’re, say, driving through rural areas. Plus, within the close confines of a car, your entire core is exposed to the radiation.

The safer solution: Keep your phone off when driving until you really need it, says Carpenter. And no matter where you are, avoid holding a cellphone directly to your noggin (the Interphone study showed gliomas were more prevalent on the side of the head people continuously pressed phones to), always keep it at least six inches or more from your body (in your purse, not your pocket), and use either speakerphone or a corded headset (not a wireless headset). Or, text up a storm. Also, don’t ever use your cellphone as a bedside alarm clock without first disabling the wireless mode.

Cordless phones

These stealth wireless threats “have become so powerful, they’re often as strong as cellphones,” says Sage. “The phone base is like a mini cell tower. It radiates 24-7 and can have a range of up to 300 feet.” Particularly suspect are digital enhanced cordless telecommunication (DECT) phones.

Preliminary blind studies have found that, when sitting beside a DECT phone base, some people experienced arrhythmia, a troubling heartbeat irregularity that could eventually lead to stroke or coronary disease, says Sage.The safer solution: You might feel somewhat retro, but “just get a corded phone with an extra-long cord so you can still walk around,” says Crofton.

Wireless routers

Your neighbourhood coffee shop’s wireless Internet access may often seem like a godsend, but the router that’s needed to provide the service is continuously emitting high levels of RF (up to 200 feet out), and that constant exposure has been linked to deadly diseases. “If the whole body is radiated by a router's RF emissions, the greatest concern is cancer, especially leukemia,” says Carpenter. Also, be aware of your at-home router and any plug-in wireless USB cards you often use.

The safer solution: Ditch your wireless router and plug your computer directly into a cable modem, says Sage. That Ethernet technology doesn’t leak RF and is often faster and more secure.

Laptops

“When you hold your laptop on your lap, what you’re essentially doing is radiating your pelvis,” says Carpenter, “so all the cancers that affect that area are of concern.” Indeed, early studies point to a heightened risk of testicular cancer for men who keep RF-emitting devices close to their belts.

For women, adds Carpenter, “the studies aren’t quite there yet, but I think we can say that anything that might cause cancer almost always causes birth defects, so pregnant women—or those wanting to become pregnant soon—should take extra precautions.”

The safer solution: Keep your laptop off your lap (if you have to rest it there, buffer it with a sturdy pillow that’s at least six inches thick). Try to use a desktop computer at home ,and treat your laptop as an on-the-go convenience. One thing to keep in mind: Laptops are a high RF radiation risk only while connected to wireless Internet, so when you're watching a DVD, fiddling around with your photos, or writing that dissertation, just disable your connection and you'll be much safer.

Baby monitors

“Baby monitors release more RF than cellphones do, and putting them next to a crib is very, very unwise,” says Carpenter. He points to a recent University of Utah study that shows RF radiation can penetrate almost entirely through a child’s brain, which doesn’t form completely until nearly 20 years of age.

“It’s very clear from all the existing research that the younger the child is, the more vulnerable he or she is to the effects of RF radiation.”
The safer solution: Consider not using a baby monitor. If you absolutely must use one, place it far from your baby's crib—at least ten to 15 feet away.
