EWG's Guide to Safer Cell Phone Use: Cellphone Radiation Research

November 2013 – Cell Phone Radiation Depends On Wireless Carrier

A series of studies quietly published over the last five years show that cell phone network technologies affect radiation exposure as much as the phone design itself. These studies, mostly overlooked by the press, indicate that users of the same mobile device can absorb starkly different amounts of radiofrequency emissions, depending on which carrier serves them.

Federal website dropped cautionary language on radiation levels after officials met with industry, documents obtained by Environmental Working Group show. Read more.


February, 2011 - Cell phone radiation alters brain activity

A team led by Dr. Nora D. Volkow, a pioneering brain imaging scientist who heads the National Institute on Drug Abuse, has reported that cell phone radiofrequency radiation alters human brain activity. The study, published by the Journal of the American Medical Association, is the first investigation to document changes in brain glucose metabolism after cell phone use. Read more.
