Wireless radiation. Our health. The questions that deserve a closer look.
The U.S. Department of Health and Human Services (HHS) is inviting families, individuals, clinicians, and researchers to share what they know about electromagnetic field exposure. That includes you.
Start with one experience. See an example beside your answer.

A request for information, or RFI, is a public invitation to share evidence, experiences and questions. Here, HHS—the U.S. Department of Health and Human Services—is asking about electromagnetic fields and health.
Families, caregivers, clinicians, researchers, and anyone with relevant information can contribute.
See what HHS is asking ↗EMF means electromagnetic fields. It is a broad term. Everyday electricity, radio signals and light belong to different parts of this picture.
The useful question is: which kind of exposure, how much, for how long, and what happened? That is why this site separates experiences, measurements and health studies.
Start with what each study actually tested. A result in rats, a result in people, and a measurement of exposure tell us different things.
Clear evidence of malignant heart tumors in the exposed male rats.
NTP findings ↗Whole-body animal exposures differ from everyday phone use.
Increases appeared in certain tissues in the follow-up analysis.
DNA findings ↗Cellular damage does not automatically lead to illness.
Mobile phone call time was not associated with brain tumor risk.
COSMOS study ↗More time and better exposure data can help address remaining questions.
A device can pass its exposure test without answering every question about long-term health.
The FCC set these limits using recommendations from 1986 and 1992. It reviewed them in 2019 and kept them.

That captures the focus on heat. The actual limits include a safety margin, so exposure must stay below levels known to cause harmful heating.
Read how the FCC explains it ↗The device test checks exposure under set conditions. It does not track someone’s health through decades of everyday use, from childhood onward.
Researchers also study long-term health. A passing device test is only one part of the evidence. See what health studies found and what they could not answer.
Three questions to keep asking.
What do we know about exposure from childhood into old age, including people who may be more vulnerable?
The NTP system studied 2G and 3G signals. It does not represent newer technologies.
6G is in development. Follow the ITU roadmap ↗
What are we exposed to across a whole day, as we move between devices and places?
Wireless devices transmit when their radios are active. Appliances produce power-frequency fields; smart models may also use Wi-Fi. Distance and use matter.

Reports include concentration difficulties and head pain.
Symptoms can affect energy and everyday routines.
Some people describe burning, tingling, or redness.
The impact can show up in what you stop feeling able to do. Work and social connection matter too.
Finding it hard to settle at a computer, stay focused, or face another work session.
Illustrations of day-to-day difficulties, not diagnostic signs of EMF exposure. People may experience these changes for many reasons.
The 46-study review found no robust evidence that EMF exposure triggered symptoms under the conditions tested. These reports are not proof of causation.
WHO: reported experiences ↗WHO: symptom reports ↗Newer symptom studies, memory & a writing example →I believe I spent years struggling with impacts from my surroundings before I recognized a pattern. Time in hybrid and electric vehicles helped me put words to a familiar feeling.
I built this resource to help others explore the evidence, ask questions and share what they have noticed.
