US National Toxicology Program Cell Phone Study Report Released

The National Toxicology Program (NTP) has been conducting experiments in rats and mice on potential health hazards from cell phone radiofrequency radiation. Today, the NTP released a report on some important study findings.

Here are some key points about the cell phone study:

  • The nomination for the NTP to study cell phone radiofrequency radiation was made by the U.S. Food and Drug Administration.
  • These are the largest most complex studies ever conducted by the NTP.
  • For the studies, rodents were exposed to frequencies and modulations currently used in cellular communications in the United States. Rats and mice were exposed for 10-minute on, 10-minute off increments, totaling just over 9 hours a day from before birth through 2 years of age.
  • The NTP found low incidences of tumors in the brains and hearts of male rats.
  • NTP has provided these findings to its federal regulatory partners to enable them to have the latest information for public health guidance about safe ways to use cellular telephones and other radiofrequency radiation emitting devices.

Likewise, the NTP is providing the findings to the public. A report has been posted at The report is titled, “Report of Partial Findings From the National Toxicology Program Carcinogenesis Studies of Cell Phone Radiofrequency Radiation in Hsd: Sprague Dawley SD Rats (Whole Body Exposure).” Studies in mice and further evaluations of the rat studies are continuing. The complete results from all the rat and mice studies will be available for peer review and public comment by the end of 2017.
