11 Ways to Protect Against Cell Phone Radiation

Ninety-one percent of Americans and nearly 5 billion people worldwide use a cell phone. Increasingly, cell phones are becoming a vital part of our lives, functioning as our primary mode of personal and business communication as well as our calendars, cameras, MP3 players, and address books. It is hard to imagine a world where we didn’t have all these functionalities at our fingertips. But at what cost to our health?

Green America decided to tackle the subject “Do Cell Phones Cause Cancer?”

We fully expected to turn up some inconclusive evidence that excessive cell phone use may be linked to some ill health effects, and people should be careful about talking on a cell for hours a day—but when we dug into the research, what we found was truly frightening.

Shortly after we published this issue, the World Health Organization declared cell phone radiation a “possible carcinogenic,” putting it into the same category as lead and the dry cleaning chemical perchloroethylene.

Here’s what you can do to protect yourself from potential harm from radio-frequency radiation emitted by these devices:

1. ALWAYS USE A HANDS-FREE HEADSET OR THE SPEAKERPHONE SETTING WHEN TALKING ON YOUR CELL PHONE. Some researchers say a wired headset, especially a “hollow tube” headset you can special-order—which will be labeled as such and uses hollow tubes rather than wires to conduct sound—is the best. But even a Bluetooth wireless headset will reduce your radio-frequency radiation exposure by several thousandfold.

2. KEEP THE PHONE OFF YOUR BODY. Carry your phone in a purse or bag with the antenna (back of the phone) pointed away from you, not in your pocket or bra. When you’re talking on it (with a headset or on speakerphone) put it on a table in front of you. Just a few inches can substantially reduce your radiation exposure.

3. TEXT INSTEAD OF TALKING. Holding your cell phone away from your head to send text messages exposes you to less radiation than talking on it without a headset.

4. TURN IT OFF. Phones only emit radio-frequency radiation when they’re searching for or receiving a signal, so a phone that’s off or in “airplane mode” is safe.

5. REPLACE CORDLESS PHONES WITH CORDED MODELS. Cordless phones can emit as much radiation as cell phones, and the charging station constantly emits radiation.

6. USE A LOW-RADIATION CELL PHONE. Cell phone retailers aren’t required to display the specific absorbency rate (SAR), or the amount of radiation a phone causes your body to absorb. Search FCC.gov/cgb/sar to find out the SAR level of your model, or consult the Environmental Working Group’s online database: EWG.org/cellphones. But no matter how low the SAR of your phone is, it’s still important the phone away from your head and body whenever possible.

7. KEEP YOUR CELL PHONE, CORDLESS PHONE, AND WIRELESS MODEM AWAY FROM YOUR HEAD. All three will expose you to radio-frequency radiation, so banish all three from the bedroom or, at least, keep them away from your head and body. If you must have wireless Internet, turn off your router when you’re not using it, especially at night—a power strip with a timer can help.

8. KEEP YOUR PHONE FULLY CHARGED. When a cell phone’s signal strength is weak or blocked, it has to work harder—and consequently emits more radiation.

9. BE WARY OF DEVICES THAT CLAIM TO BLOCK EMF EXPOSURE. A Google search yielded 236,000 results for “EMF protection,” most of which were sites selling “protective” devices ranging from pendants and crystals to microchips and herbal remedies. Most experts agree that many are based on quasi-science and there’s no evidence that they work. Some “EMF shields” for your phone can actually increase the amount of radiation that it emits, since they block the signal and the phone has to work harder.

10. DON’T GIVE CELL PHONES TO YOUNG CHILDREN AS TOYS OR PACIFIERS. If you occasionally let your small tot play Pac-Man on your cell phone, put it into “airplane mode” so it won’t search for a signal—which means it won’t emit radiation.

11. TAKE CARE WITH OLDER CHILDREN. Children are more susceptible to potential harm from radio-frequency radiation than adults. If you give your children a cell phone for safety reasons, also give them a headset and encourage them to text or use the speakerphone instead of putting the phone close to their heads.

    good tips. never heard of “hollow tubes” before 🙂

    Very interesting since we have been saying this in our Waldorf community since 1999 or before. My husband has always had a cell phone for work, since they were the size of a big package, so he could call us from the road. All the cell phones we have owned over the years times 10 is what worries me. Where do they all end up? I know I have a lot of them in the garage but what does one do with the the leather accessories that cover it? And all the money we have spent over the years could certainly have been invested into something more exciting like travel. I am getting rid of mine soon. I will only carry one when I travel out of state because there are no pay phones any more.u00a0

    There are differing opinions on radiation effects from cell phone. It is better to be cautious. Your tips are very useful.nnDr.A.Jagadeeshu00a0 Nellore(AP),IndianE-mail: anumakonda.jagadeesh@gmail.com

    Appropriate protection against cell phones freely radiating inside car

    What pathetic fools you americans are. Any reasonably intelligent kid knows that a 2-way radio (or mobile phone) antenna has to be outside a car, not inside it. *This* is the way this problem is solved, not through your trash:

      Why jump to the assumption that Peter is an American?

  • Studies conducted by numerous scientific teams in several nations have raised troubling questions about possible associations between heavy cell phone use and serious health dangers. That’s why I investigated ways to cell phone radiation protection . I read about Pong Research cases, Pong technology is custom-designed for each mobile device and works to redirect radiation away from your head and body. I hesitated about it, anyway, I bought a case Pong because is the only technology proven in FCC-certified laboratories to reduce the exposure to mobile device radiation by up to 95% below the FCC limit without compromising the device’s ability to communicate.

    I read that the cell phones emit a dangerous non-ionizing form of electromagnetic radiation; radiation which can be absorbed by the tissues and cells which come into close contact with the phone. So I looked ways to reduce cell phone radiation effects . Right when I lost all hope, I came across WIRED magazine and found a review of Pong Research cases. After seeing the great feedback on their products, I bought one and it finally put an end to the problem.

    There is also new way to protect yourself and your family from cell phone radiation. This is a new mobile app called Talk Intact. It reduces cell phone radiation exposure during the calls. It does not pretend to stop the radiation completely, but the idea to decrease it is very interesting. https://play.google.com/store/apps/details?id=com.talkintact.tiapp
