Cell Phones

Personal (cellular) telecommunications is a rapidly evolving technology that uses radio frequency energy or radiation for mobile communication. Most Americans use cell phones. Given this large number of users, if adverse health effects are shown to be associated with cell phone use, this could potentially be a widespread public health concern. Current scientific evidence has not conclusively linked cell phone use with any adverse health problems, but more research is needed.

What NIEHS is Doing on Cell Phones 

The National Toxicology Program (NTP) headquartered at NIEHS is leading the largest laboratory rodent study to date on cell phone radio frequency. The NTP studies will help clarify any potential health hazards from exposure to cell phone radiation . The studies are designed to mimic human exposure and are based on the frequencies and modulations currently in use in the United States.

The NTP has worked closely with radiofrequency experts from the National Institute of Standards and Technology (NIST) to design highly specialized study facilities to specify and control sources of radiation and to measure their effects on rodents. The NTP studies are designed to look at effects in all parts of the body. Final study results are expected in 2016.

In addition to the NTP studies, the NIEHS is funding researchers at the University of California, Los Angeles , to study whether exposure to cell phones in childhood can affect the nervous system.
