When I am called to work as an Electromagnetic Radiation Specialist (EMRS) in the home of two or more people, there is usually at least member of the family who serves in the role of Doubting Thomas. “I am not sure I really believe all this,” one husband said to me recently. The doubts typically subside to some degree when family members can witness the numbers popping up from the meters I use to measure the four types of EMFs – making the invisible visible! 
Yet the doubts are understandable, since the web is full of industry-funded studies that seek to “war game the science”, as an internal memo from Motorola executives revealed in 1994, thanks to the investigative work of Microwave News.
My work doing EMF inspections and teaching EMF science and solutions has always flowed from my long-term love of radiant health and prevention, grounded in peer-reviewed science that is not confounded by conflicts of interest. In my deep dive on this complex issue over the past 14 years, I have found that the science of EMF health effects is plentiful and very clear. We just need to know where to look for it, and to be discern which studies are not confounded by conflicts of interest.
To make the search easier, below are several of the most reliable websites on the health effects of EMFs (electromagnetic fields):
- Physicians for Safe Technology, founded by Cindy Russell, MD, former president of the Santa Clara County Medical Society, CA
- The Environmental Health Trust, providing science, policy support, and education to protect human health and our environment.
- EMF-Portal hosting more than 46,000 publications from EMF science worldwide
- The Building Biology Institute, which provides professional training and quantitative approach
- And SaferEMR.com – hosted by Joel M. Moskowitz, Ph.D., School of Public Health, UC- Berkeley
Some of the latest news on Wireless Radiation and Health
Dr. Moskowitz recently shared this new update: Effects of Exposure to Electromagnetic Fields: Thirty years of research Featured here are summaries shared from Dr. Henry Lai, Professor Emeritus at the University of Washington, Editor Emeritus of the journal, Electromagnetic Biology and Medicine, and an emeritus member of the International Commission on the Biological Effects of EMF. Dr. Lai’s sets of abstracts cover from 1990 through May 8, 2025. “Dr. Lai reports that the preponderance of research has found that exposure to radio-frequency radiation (RFR – wireless radiation) and extra-low frequency fields (ELF – like from wiring in your home and power lines) 
produces oxidative effects or free radicals, and damages DNA. Moreover, the preponderance of studies that examine genetic, neurological and reproductive outcomes has also found significant effects. Among hundreds of studies of RFR, 72% – 89% reported significant effects. Among hundreds of studies of ELF, 77% – 91% reported significant effects.”
To narrow this down: As of May 12, 2025:
- 89% (n=359) of 407 studies on radio-frequency radiation and oxidative effects (or free radicals) published since 1997 reported significant effects
- 90% (n=303) of 332 extra-low frequency fields (EMF) and oxidative effects (or free radical) studies published since 1990 reported significant effects
You can find far more effects from Dr. Lai if you follow the link to the studies. Yet oxidative stress undergirds the pathophysiology of nearly every chronic condition. So it is a great starting point for looking at EMF health effects. Oxidative damage advances aging, causes inflammation, increases pain, and makes it difficult to repair DNA, thereby increasing cancer risks.
Another important new study: The World Health Organization partially funded a very important study on cancer and 
wireless radiation: Effects of radiofrequency electromagnetic field exposure on cancer in laboratory animal studies, a systematic review, published in April in Environment International. This analysis of 54 animal studies concluded that there is high certainty of the evidence linking cell phone radiofrequency (RF) radiation to two types of cancer in animals. In response, leading scientists from the International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) are calling for immediate policy action to protect public health and the environment, warning that further delay could have serious consequences amid the global surge in the use of wireless communication devices. While some countries have policies to protect children from the adverse effects of wireless radiation, we do not (yet!) have that protection in the U.S.
To get a sense of what children are often exposed to: Oncologist and cancer epidemiologist Lennart Hardell, MD, PhD, recently published High Radio-Frequency Radiation in the Surroundings of 10 Schools in Öbro, Sweden. This study found that maximum levels in and around schools ranged from 10,716 to 68,452 μW/m2 . These levels far exceed the European Academy of Environmental Medicine’s EMF guidelines for daytime RF radiation exposure: 10 – 1,000 μW/m2 (microwatts per meter squared), nighttime 1-100 μW/m2, and for sensitive persons 0.1-10 μW/m2. (It is always crucial to use the maximum exposures, as these are what cause the most damaging biological effects. An assessment like this is only a snapshot of what is occurring 24/7).
These extreme levels reflect my own findings. (However, in local Buncombe County Schools in the Asheville area, levels are much lower after the district was intentional about reducing the radiation risks, following much of the guidance we provided in this webinar by SafeTech NC.) Since children typically 
are exposed to extreme exposure levels in most schools, it is imperative for them to recover from those exposures in a safe, low-EMF environment at home. Children are most vulnerable to wireless radiation, and will have a lifetime of cumulative exposures.
So what can we do about all of this bad news? Here are some easy ways to get started:
1. Create a low-EMF sleep sanctuary! This is the most important intervention, preventing all four types of EMF exposures overnight, so the body can be protected when it is most vulnerable (during sleep) and can heal from the day’s exposures. This is the most important intervention I assist with during an EMF assessment.
2. Hard-wire internet connections, or at least use one of several means to measurably reduce exposures, like reducing the power level of your router, turning it off at night, or covering it with certain shielding fabrics.
3. Use your cell phone only sparingly, keeping it off your body and brain. The non-profit I manage, SafeTech NC, hosts some ideas on safer ways to use your phone.
