Cell Phone Radiation Biological and Health Effects Dr. Devra Davis Explains – Environmental Health Trust

You’ve probably heard of the electromagnetic (EMF) spectrum. Most of us understand EMFs as the energized waves moving though the air. The longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
Visible light is the range of the spectrum where our eyes are able to compute waves into images.
The rest of the spectrum — not visible to the naked eye — is separated into two categories as ionizing and non-ionizing radiation. Visible light can be thought of as a dividing line between these two types of radiation.
Examples of ionizing radiation are gamma and X-rays. These higher frequency wavelengths are moving at super-fast speeds. In fact, they are so energetic that they can knock electrons out of atoms, damaging our DNA. These effects are well known to lead to cancer.
Non-ionizing radiation — such as electricity, Wi-Fi and cell phone radiation — occurs at lower frequencies, with waves that are far less energetic yet still incredibly fast. However these lower frequencies are also linked to DNA damage.
For example;
  • Countries run electricity on frequencies of 50 Hz and 60 Hz, meaning the waves are moving 50 to 60 times per second.
  • Cell phones use frequencies from around 900 MHz to 1900 MHz, meaning the waves are moving 900,000,000 to 1,900,000,000 times per second.
  • Wi-Fi uses a frequency of 2.45 GHz, which means the waves are moving 2,450,000,000 times per second.
  • 5G will use higher frequencies such as 28.35 GHz, which means the waves are moving 28,350,000,000 per second.
The US FCC has even allocated frequencies up to 3 THz for 7G. This means the waves move 3,000,000,000,000 a second.
“Non-ionizing” radiation may not immediately rip apart the cells in our bodies but that does not mean it is safe.
Chronic exposure to non-ionizing radiation, even at low densities, has been found to have a biological impact and can alter the way our body’s living cells communicate with each other. Dr. Devra Davis explains in this short YouTube video how it happens.
Dr. Devra Davis busts the myth that non-ionizing radiation is incapable of damaging our body. She explains how the pulsed nature of the radiation is problematic. “ It has nothing to do with the power.” Yes, cellphone radiation CAN lead to DNA damage. Learn more at http://ehtrust.org

Devra Davis, PhD, MPH Visiting Professor of Medicine at Hebrew University Hadassah Medical School, Israel, and at Ondokuz Mayis University Medical School, Turkey and President of Environmental Health Trust

She was Founding Director for both the Board on Environmental Studies and Toxicology of the U.S. National Research Council and for the Center for Environmental Oncology, University of Pittsburgh Cancer Institute.  Davis served as an appointee to the Chemical Safety and Hazard Investigation Board and was a member of the Board of Scientific Counselors of the National Toxicology Program.  

Dr.  Davis started  working on climate change as an environmental health issue decades ago and as one of the scientists who was a lead author on the Intergovernmental Panel on Climate Change, she was part of the team of scientists  awarded the Nobel Peace Prize along with honorable Al Gore.

A 2022 review Genotoxic effects of electromagnetic field radiations from mobile phones published in the journal Environmental Research documents that the majority of studies find exposure increases the frequency of micronuclei, chromosome aberrations, DNA adducts, DNA single and double strand breaks at the molecular level in vitro and in vivo. “Investigations reporting that EMF-RF-ELF exposures are are genotoxic outnumber the reports that the EMF-RF-ELF exposure are not harmful to the human population.”  The paper concludes “the  repeated EMF-RF-ELF exposures exert a negative effect on human health and cause mutagenesis and cancer in humans. It will be prudent to follow ALARA (as low as reasonably achievable) principle to minimize the adverse effect on humans.


The study Role of 2.4 GHz radiofrequency radiation emitted from Wi-Fi on some miRNA and faty acids composition in brain published in Electromagnetic Biology and Medicine  found long term exposure to 2.4 GHz Wi-Fi has the potential to alter rno-miR-181a-5p expression and the fatty acid percentage of some membrane lipids in the brain. The researchers conclude that the uncontrolled use of wireless “whose use and diversity have reached incredible levels with each passing day and which are increasing in the future, may be paving the way for many diseases that we cannot connect with today.”

The roles of intensity, exposure duration, and modulation on the biological effects of radiofrequency radiation and exposure guidelines reviewed 112 studies with low-intensity RFR exposures finding that biological effects could occur at a median specific absorption rate of 0.0165 W/kg.  This data indicates  that biological effects can occur at a level which is much lower than most current international RFR exposure guidelines. “Given the large body of work as illustrated in Supplement 1, the SAR at, or below, 4 W/kg as a safe threshold is insupportable.”
