High Exposure to Radio Frequency Radiation
November 1, 2018 - The National Toxicology Program (NTP) found clear evidence that exposure to radio frequency radiation, as in 2G and 3G cell phones, resulted in cancerous heart tumors in male rats. The researchers found some evidence of tumors in the brains and adrenal glands of male rats.
The National Toxicology Program (NTP) conducted studies in animals of exposure to high levels of radio frequency radiation (RFR) that was comparable to 2G and 3G cell phone networks. These cell phones operate within a range of frequencies of 700 – 2700 megahertz (MHz). The NTP studies found that high exposure to RFR (900 MHz) was associated with:
- Clear evidence of tumors in the hearts of male rats. The tumors were malignant schwannomas.
- Some evidence of tumors in the brains of male rats. The tumors were malignant gliomas.
- Some evidence of tumors in the adrenal glands of male rats. The tumors were benign, malignant, or complex combined pheochromocytoma.
It was unclear if tumors observed in the studies were associated with exposure to RFR in female rats (900 MHz) and male and female mice (1900MHz). This is also known as equivocal evidence.
The final conclusions represent the consensus between NTP and a panel of external scientific experts who thoroughly reviewed the draft NTP technical reports at a public meeting in March 2018.
The $30 million NTP studies, conducted for more than 10 years, are the most comprehensive assessment to date of health effects in animals exposed to RFR with modulations used in 2G and 3G cell phones. 2G and 3G networks were standard when the studies were designed.
