FDA statement on the National Toxicology Program’s report on radiofrequency

5 November, 2018.

U.S. Food and Drug Administration (FDA) published a statement on final reports of NTP study on carcinogenicity of radiofrequency radiation from cell phone.

Main conclusions:
"We reviewed the recently finalized research conducted by our colleagues at the National Toxicology Program (NTP), part of the National Institute of Environmental Health Sciences within the National Institutes of Health, on radiofrequency energy exposure. After reviewing the study, we disagree, however, with the conclusions of their final report regarding 'clear evidence' of carcinogenic activity in rodents exposed to radiofrequency energy.
In the NTP study, researchers looked at the effects of exposing rodents to extremely high levels of radiofrequency throughout the entire body. This is commonly done in these types of hazard identification studies and means that the study tested levels of radiofrequency energy exposures considerably above the current whole body safety limits for cell phones.
Doing this was intended to help contribute to what we already understand about the effects of radiofrequency energy on animal tissue. In fact, we only begin to observe effects to animal tissue at exposures that are 50 times higher than the current whole body safety limits set by the FCC for radiofrequency energy exposure.
Our colleagues at NTP echoed this point in a statement earlier this year about their draft final report, including the important note that 'these findings should not be directly extrapolated to human cell phone usage.' We agree that these findings should not be applied to human cell phone usage."
