National Toxicology Program to Release RadioFrequency Radiation Technical Report February 2, 2018


National Toxicology Program to Release Draft Technical Reports on RadioFrequency Radiation February 2, 2018

The National Toxicology Program has given notice that the full draft report of their studies on the carcinogenicity of cell phone radiofrequency radiation will be released to the public on February 2, 2018. The peer review is scheduled for March 26-28 at National Institutes of Health Environmental Health Sciences Research Triangle Park, North Carolina.

The National Toxicology Program (NTP) will hold a media telebriefing to summarize and answer questions. 

Who: John Bucher, Ph.D., NTP Senior Scientist

When: Friday, Feb. 2, 1:00 p.m. EST

Where to call: In the U.S. and Canada, call 785-424-1676 or toll free 888-632-3384

Outside the U.S. and Canada, call 785-424-1676 Passcode/Conference ID: CELLPHONE

The NTP had released findings from the rat brain and heart in June 2016 and gave a presentation. They later presented findings of genotoxicity in September 2017. This February 2018 release will be the full technical report with findings from all tissues (not just the heart and brain) – from both the rat and mice studies.

“SUMMARY: The National Toxicology Program (NTP) announces a meeting to peer review two Draft NTP Technical Reports on Cell Phone Radiofrequency Radiation. These reports present the results of NTP studies conducted to evaluate the impact of cell phone radiofrequency radiation exposure in mice and rats. NTP studied two system modulations: Global System for Mobile Communications and Code Division Multiple Access.

The two draft NTP technical reports will be available by Feb. 2, 2018 on the Upcoming Peer Reviews of Draft NTP Technical Reports page. 

  • March 12, 2018 is the deadline for written public comment submissions.
  • March 12, 2018 is the deadline for oral comment registration.
  • March 28, 2018 is the deadline for registration for attendance and webcast.
  • Registration is required to view the meeting via the webcast.

Federal Register notice, agenda, registration, and other meeting information are available on the Upcoming Peer Reviews of Draft NTP Technical Reports page.

In 2016 National Toxicology Program scientists released these findings:

  • Increased incidences of glioma (a rare, aggressive and highly malignant brain cancer) as well as schwannoma (a rare tumor of the nerve sheath) of the heart were found in both sexes of rats, but reached statistical significance only in males.
  • Increased incidences of rare, proliferative changes in glial cells of the brain and in Schwann cells (nerve sheath) in the heart of both sexes of rats, while not a single unexposed control animal developed these precancerous changes.

In 2017 the NTP presented data that found DNA damage was significantly increased in:

  • The frontal cortex of male mice from CDMA and GSM cell phone radiation,
  • Peripheral leukocytes of female mice from CDMA only, and
  • The hippocampus of male rats from CDMA only.
  • There were no significant increases in micronucleated red blood cells in rats or mice.

The authors concluded that, “exposure to RFR [radio frequency radiation] has the potential to induce measurable DNA damage under certain exposure conditions.”
