Report Stirs Debate on Cell Phone Safety

Environmental Working Group Warns of Health Risks; Other Experts Disagree

EWG Ranks Cell Phones by Radiation Emission

EWG's scientists say they are still using their cell phones, but they suggest consumers buy phones with the lowest radiation emissions.

The EWG issued a mobile phone guide, rating more than 1,000 cell phones on their radiation emissions. A high ranking on the list does not mean the phone is the best or the safest, but simply that the phones had the lowest emissions among the models for which data were available.

Here are the phones on the top 10 list for lowest radiation emissions:

  • Samsung Impression
  • Motorola RAZR V8
  • Samsung SGH-t229
  • Samsung Rugby
  • Samsung Propel Pro
  • Samsung Gravity
  • T Mobile Sidekick
  • LG Xenon
  • Motorola Karma
  • Sanyo Kantana II

The popular iPhone 3G landed about midway on the complete list. Data on emissions for several phones were not available, the EWG says.

Much lower on the list, the phones with the highest radiation emissions were:

  • T-Mobile Shadow
  • Motorola W385
  • Blackberry Curve 8330
  • T-Mobile myTouch3G
  • Motorola MOTO VU204
  • Kyocera Jax S1300

 

Second Opinion

''There has been a flurry of attention from advocacy groups regarding cell phones and cancer," says Michael Thun, MD, the emeritus head of epidemiology research for the American Cancer Society, who reviewed the report for WebMD.

The conclusion that evidence of ill effects is rising is faulty, he tells WebMD. "Basically the idea that there is a sea change in the evidence in the past two or three years is incorrect," he says. "Essentially this report focuses on studies that support their hypothesis that cell phones increase brain cancer risk. The description of the evidence selectively emphasizes the studies that suggest the risk and omit the evidence that suggests no risk."

As for the argument that earlier studies finding no ill health effects from cell phone use were not conclusive because they didn't examine long-term use, Thun points to Sweden, ''the country that has had the longest cell phone use. And there is no increase in brain cancer in Sweden."

That's true, he says, although the percent of the population there using mobile phones increased over the past two decades.

Even so, Thun says the report's conclusion -- that more government regulation of mobile phones is needed -- is reasonable.

On its web page, the American Cancer Society notes that "cell phones wouldn't be expected to cause cancer because they don't emit ionizing radiation." Says Thun: "It's nonionizing. It doesn't break up DNA."

In the view of the American Cancer Society, Thun says,  those concerned about cell phone use can choose to use a corded or cordless earpiece. ''Exposure [to the cell phones' electromagnetic waves] comes from the antenna. If you are using an earpiece, you are getting virtually no exposure.''

Despite his criticisms of the report, Thun says continued research on cell phones and health effects is crucial. "The issue is important," he says. But, he adds, ''this report presents a one-sided view of the evidence. Going forward, it is important that people who are concerned know they can limit their exposure by using an earpiece. It's also important that surveillance be continued and that evidence be reviewed in its entirely in a process that is able to look critically at the evidence."
