How to Protect Yourself and Your Family

A cell phone is a microwave radio that works on much lower power but at roughly the same wavelength as a microwave oven. More than a dozen countries today restrict the use of cell phones by children and advise precautions regarding their use, including using headsets, speakerphone, and text messaging.

Excepting for emergencies, phones should not be held next to the head. Get in the habit of using landlines and ethernet  connected electronics whenever possible. Instead of waiting for government action, here is what you can do right now to keep you and your family safe.

PERSONAL ACTION

  • Use a headset or speakerphone to reduce the amount of radiation  to the brain.
  • Your exposure drops more than exponentially as you move the phone away from your head. Even when using the speaker, hold the phone away from your torso when you are talking and be sure that the back of the phone is not close to others, especially nursing infants or other children.
  • Carry phones away from the body and not in a pocket or bra. Do not keep a phone  turned  on next to your body all day. When you are not using the phone, if it is on, stow it in a backpack, purse, or bag. If you keep it on your waist, turn it off. Do not keep a wireless headset turned  on in your ear or in your pocket when not in use.
  • Whenever possible, only use your phone when the signal quality is good. The weaker the signal, the more the radio frequency has to boost itself to get connected, increasing your exposure. Minimize  use when reception is weak (such as in a rural areas) or when you are in a metal box, such as an elevator, train, or car.
  • Prefer texting  to voice calls and when doing  so hold the phone away from your  body. Phones  typically  use less radiation to send text than  to speak, and texting  keeps radiation from your  head. However  sharing photos or videos increases  your  radiation exposure.
  • Use a corded landline at home and not a cordless phone, as these emit radio frequency radiation like that of cell phones. (Having a landline means you will have a working phone if and when electricity is cut off during  blackouts or if cell towers are not working.)
  • Teach your children about this issue. Tweens and teens and the rest of us should not sleep with a cell phone  under pillows or next to the bed all night. Use a battery alarm clock.
  • Pregnant women should keep their cell phone  away from their abdomen. New mothers should also protect their babies from the phone. Do not speak on the phone  or text while holding the device near the abdomen or the baby’s head. A fetus’s or baby’s developing brain is most susceptible to radiation.
  • Men, especially those trying to become fathers, should also keep their cell phones turned  off when in their pockets.
  • Be wary of radiation  shields and other such protective devices that are claimed to limit exposure to radiation. They may reduce the connection quality and therefore force the phone to transmit  at a higher output power.
  • Avoid using a phone or texting while driving. It’s like driving drunk.
  • Read the “fine print” from the manufacturer’s instruction manual which tells users to keep a distance between the phone and your head and body. The fine print warnings for cell phones range from a few millimeters to almost an inch. The fine print warnings on other wireless devices such as Wi-Fi routers, home cordless phone base stations and baby monitors generally state devices should be at 20 em, or about 8 inches. If people are closer than the manufacturer  stated separation distance, then they can be exposed to RF levels that violate the US government radiation limits.
  • Choose wired Internet (Ethernet cable modems) at home instead of wireless systems, if possible. Use wired computers to do as much as possible of your Internet connection and social media and streaming videos. If you do use wireless systems, unplug them during sleeping hours or when you are not using them.
  • When you connect digital devices with wired Internet  connections, remember to turn  the Wifi off and the bluetooth OFF in settings and turn  the Wifi off the router.  (Even if you are using a wired connection, the device will emit if the Wi-Fi antennas  are on.)
  • Choose non-wireless options instead of wireless for tech and accessories such as computers, laptops, printers, gaming consoles and handsets, security, mouse, keyboard, video cameras, HVAC, speakers, headphones, microphones and other accessories.

POLITICAL ACTION

More than a dozen countries advise restricting the use of cell phones by children and limiting direct exposures to the bodies and heads of adults. In the United States the Federal Communications Commission (FCC) is responsible for issuing rules on cell phones. The U.S. Food and Drug Administration (FDA) has taken the position that they do not regulate or evaluate cell phone safety before marketing, but they only act if and when a phone is found to be dangerous. The FDA does regulate microwave ovens, which use much higher power than cell phones, because leaking ovens or other uses of microwave radiation at high power have triggered heart attacks in those with pacemakers and are associated with other serious health problems.Join the Campaign  for Safer Cell Phones on our Web site www.ehtrust.org and write to your member  of Congress if you want access to better  information on these matters. We call on local, state, and national government and the private sector to:

  • Require that warning labels about safer cell phone  use be applied to cell phones.
  • Require that phones be sold with earpieces and speakerphones.
  • Increase public awareness about the specific absorption rate of all phones and ways to reduce exposures to radiation.
  • Conduct a major review and revision of safety standards, incorporating state­ of-the-art science, and support a major multidisciplinary independent research program on cell phones.
  • Develop specific recommendations about lowering direct radiation  to the head.
  • Conduct a national survey of radio frequency radiation  exposure (the last one was done in 1980) and develop monitoring of heavy cell phone  users by creating access to cell phone billing records to qualified researchers.
  • Require that pre-market testing be done before new technologies are deployed.
