Cell phones and radiation: 10 best and 10 worst

How much radiation does your cell phone emit? It's easy to find out the answer thanks to the Environmental Working Group's new online guide to cell phone emissions.

The non-profit research and advocacy group ranked over 1,000 different cell phones according to radiation levels. It looked at the publicly available, but difficult to find, specific absorption rate (SAR) for each phone. SAR is a measure of how much radiation is absorbed by the body when the phone is sending a signal to the network. (Your phone only emits radiation when you talk or text.)

The jury is still out on whether cell phone radiation is harmful to human health, but it certainly won't hurt to limit your exposure to cell phone radiation when you can. Several research teams from different countries report a higher risk of developing brain and salivary gland cancer among high-volume, long-term cell phone users compared to people who use cell phones less often, according to EWG. For example, a 2009 scientific analysis of studies done in Sweden and several other European countries found a consistent pattern of an increased cancer risk after more than 10 years of mobile phone use.  

"The data is still conflicting and the science isn't settled," says Jane Houlihan, research director at EWG. "But there is enough evidence now that it makes sense for people to take personal action while the teams of scientists and health agencies sort through the data." Houlihan also points out that health agencies in six different countries are warning people to cut their exposure to cell phone radiation, particularly when it comes to children. 

Taking personal action can be as simple as adding radiation emissions to the list of criteria you use when purchasing a new cell phone, especially when it's for your child.

How much of a difference can choosing a low-radiation phone make? High-radiation cell phones on EWG's list emit eight times more radiation than those on the low end of the spectrum.

Can't find your phone? Check the entire list of 1,000 phones or search for your model. If your cell phone isn't on EWG's list, then search the Federal Communications Commission website to get your phone's SAR value. You can then compare it to the models in EWG's guide to see how it stacks up against the competition.

Buying a new cell phone isn't your only option for limiting your exposure to cell phone radiation. Keeping your phone away from your head and body is the best thing you can do.

Here are some tips adapted from EWG's guide to reducing cell phone radiation exposure:

  • Use speakerphone or a headset. There's no consensus on whether it's safer to go with a wired or wireless headset, but headsets emit less radiation than cell phones.

  • Send text messages instead of talking. Phones use less power and therefore emit less radiation to send text than voice. It also keeps radiation away from your head.

  • Stay off the phone when you have a poor signal. Your phone will emit more radiation to get the signal to the tower when there are fewer signal bars on your phone.

    This "RF radiation from phones gives you cancer" is bunk. The list is still useful, though; if you want a phone that provides the best coverage regardless of where you are, get one from the "worst" list. :)

    Hey zorinlynx, high radiation doesn't mean great coverage, it just means a poorly made, leaky product! Go ahead & buy crap if you prefer, & in a few years, enjoy the tumor to go along with it (especially for your kids).

    I always talk with my cell phone on my right ear and recently I had a hearing test and have lost 35% of my hearing on that ear. I used to talk a lot on my cell phone because I have no house phone. Ever since learning that I'm nervous to find out if cell phone radiation really does harm us.

    Well, This is better than the diet stuff they post all the time. You know: If you eat anything other than celery sticks you'll die of a heart attack.

    I really hate when people put together stories like this because they didn't stay awake in HS chemistry. If you are going to try and scare people at least support with studies and facts that show there is a link to cancer (2 studies that come to mind where done by Denmark and WHO. Both showed there was no chance of getting cancer from a cellphone). Cellphones uses RF radiation which is a form of non-ionizing radiation. In case you slept through chemistry RF radiation is very weak and thus does not have the energy required to break ionic bonds (which is need to harm DNA and thus cause cancer). Visible light is 10,000 times as powerful as RF radiation. You have a better chance of stopping cancer by living in the dark than by getting rid of your cellphone.

    you get more radiation from standing in front of your microwave for 30 secs. than talking on your phone for 4 hours

    Jason L: the fact that it is non-ionizing does not mean it is not harmful. Agreed that most people these days don't have any scientific knowledge, and there is a lot of bogus science and scaremongering/conspiracy theories these days. You may want to read "The Body Electric" or "Cross Currents" to get more information on this topic. I think we don't fully know the consequences of cell phone use yet, we'll know much better in the future.
