Cell Phone Radio Frequency Radiation: NTP conducted two-year toxicology studies in rats and mice to help clarify potential health hazards, including cancer risk, from exposure to RFR like that used in 2G and 3G cell phones which operate within a range of frequencies from about 700–2700 megahertz (MHz). These were published as Technical Reports in November 2018.
The NTP studies found that high exposure to RFR (900 MHz) used by cell phones was associated with:
- Clear evidence of an association with tumors in the hearts of male rats. The tumors were malignant schwannomas.
- Some evidence of an association with tumors in the brains of male rats. The tumors were malignant gliomas.
- Some evidence of an association with tumors in the adrenal glands of male rats. The tumors were benign, malignant, or complex combined pheochromocytoma.
- NTP scientists found that RFR exposure was associated with an increase in DNA damage. Specifically, they found RFR exposure was linked with significant increases in DNA damage in:
- the frontal cortex of the brain in male mice,
- the blood cells of female mice, and
- the hippocampus of male rats.
Effects of Cell Phone Radiofrequency Signal Exposure on Brain Glucose Metabolism:These results provide evidence that the human brain is sensitive to the effects of RF-EMFs from acute cell phone exposures. The findings of increased metabolism in regions closest to the antenna during acute cell phone exposure suggest that brain absorption of RF-EMFs may enhance the excitability of brain tissue.
Mobile phones, cordless phones and the risk for brain tumors: The Hardell-group in Sweden conducted during 1997-2003 two case control studies on brain tumors including assessment of use of mobile phones and cordless phones.
Cardiovascular disease and EMF: Time to identify emerging environmental risk factors: The WHO’s International Agency for Research on Cancer (IARC) appointed an expert panel to examine the evidence related to cancer in 2011 which classified RF-EMR as a group 2B possible carcinogen.
Impact of radio-frequency radiation on DNA damage and antioxidants in peripheral blood lymphocytes of humans residing in the vicinity of mobile phone base stations: Radio-frequency radiations (RFRs) emitted by mobile phone base stations have raised concerns on its adverse impact on humans residing in the vicinity of mobile phone base stations.
The effects of radio-frequency electromagnetic radiation on sperm function: Mobile phone usage has become an integral part of our lives. However, the effects of the radio-frequency electromagnetic radiation (RF-EMR) emitted by these devices on biological systems and specifically the reproductive systems are currently under active debate.
Nerve Cell Damage in Mammalian Brain after Exposure to Microwaves from GSM Mobile Phones: The possible risks of radio-frequency electromagnetic fields for the human body is a growing concern for our society. We have previously shown that weak pulsed microwaves give rise to a significant leakage of albumin through the blood–brain barrier. In this study we investigated whether a pathologic leakage across the blood–brain barrier might be combined with damage to the neurons.
The effect of 4.5 G (LTE Advanced-Pro network) mobile phone radiation on the optic nerve: Findings obtained in this study support optic nerve damage. These results point out an important risk that may decrease the quality of life.
