Electromagnetic Radiation Safety, March 28, 2018
Eleven experts convened by the National Toxicology Program (NTP) over a three day period to review the draft technical reports from the NTP’s cell phone radiation studies concluded that there is “clear evidence” that exposure to cell phone radiation caused a rare cancer in the hearts of male rats, and there is “equivocal evidence” for the hearts of female rats.
The expert panel also reported “some evidence” that cell phone radiation exposure caused brain cancer in male and female rats and cancer of the adrenal glands in male rats. Additionally, “equivocal evidence” of cancer risk was reported in the pituitary, adrenal, and prostate glands and pancreas and liver in male rats and adrenal glands in female rats.
The mice in the study, exposed to a different cell phone radiation frequency than the rats (1800 MHz vs. 900 MHz), displayed less evidence of cancer risk. Equivocal evidence of cancer risk from cell phone radiation was reported for lymphoma in male and female mice. Equivocal evidence was also reported for skin, lung, and liver cancer in male mice.
In seven instances, the expert group upgraded the evaluations of evidence published by NTP staff in the draft technical reports. Thus, the NTP scientists appear to have been overly conservative in their assessment of the hazards of long-term exposure to cell phone radiation.
A table which compares the evaluations of evidence of carcinogenicity prepared by NTP staff with the expert committee’s findings is available at:
