A public call for answers · 2026

RFK Jr. is asking.

Your experience
could make
a difference.

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.

YOUR STORY.
THE BIGGER PICTURE.

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.

A quick translation

What do we mean by EMF?

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.

WHAT THE TESTS
ACTUALLY TELL US.

Start with what each study actually tested. A result in rats, a result in people, and a measurement of exposure tell us different things.

01 / ANIMAL STUDYRadiofrequency exposure
NTP · 2018

Tumors in
male rats.

Clear evidence of malignant heart tumors in the exposed male rats.

NTP findings ↗

A measure of
human risk.

Whole-body animal exposures differ from everyday phone use.

02 / LABORATORY ANALYSISExposed rats & mice

DNA damage
in some tissues.

Increases appeared in certain tissues in the follow-up analysis.

Proof of disease

Cellular damage does not automatically lead to illness.

LIFE IS BIGGER
THAN A LAB TEST.

A device can pass its exposure test without answering every question about long-term health.

U.S. wireless RF limits1996

Adopted 30 years ago.

The FCC set these limits using recommendations from 1986 and 1992. It reviewed them in 2019 and kept them.

Cartoon scientists watch a temperature gauge connected to a hamburger while a Wi-Fi router sends signal arcs toward it.
A cartoon metaphor for the heating question, not an actual safety study.
The main goal: prevent harmful heating

So, as long as it “doesn’t cook us”?

That captures the focus on heat. The actual limits include a safety margin, so exposure must stay below levels known to cause harmful heating.

Now ask the bigger question

What happens over a lifetime?

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.

01

A lifetime
of exposure.

What do we know about exposure from childhood into old age, including people who may be more vulnerable?

A whole day.
Many sources.

What are we exposed to across a whole day, as we move between devices and places?

Wireless signals RF ↗
  • Phone
  • Wi-Fi
  • Wireless earbuds
  • Wireless controller
  • Wi-Fi doorbell
  • Laptop

Wireless devices transmit when their radios are active. Appliances produce power-frequency fields; smart models may also use Wi-Fi. Distance and use matter.

What people report.

REPORTED SYMPTOMS · CAUSE NOT ESTABLISHED

Headaches.
Difficulty focusing.

Reports include concentration difficulties and head pain.

Fatigue.
Disrupted sleep.

Symptoms can affect energy and everyday routines.

Tingling.
Skin sensations.

Some people describe burning, tingling, or redness.

When everyday life gets harder.

The impact can show up in what you stop feeling able to do. Work and social connection matter too.

Not feeling up
to desk work.

Finding it hard to settle at a computer, stay focused, or face another work session.

Pulling back
from social plans.

Wanting to see friends, but feeling too drained or uncomfortable to join in.

Illustrations of day-to-day difficulties, not diagnostic signs of EMF exposure. People may experience these changes for many reasons.

Experiences matter.
So does finding the cause.

The 46-study review found no robust evidence that EMF exposure triggered symptoms under the conditions tested. These reports are not proof of causation.

Help me tell my story

I’M MICAH.
THIS IS PERSONAL.

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.

Read my story
  1. The experiencesSchool, the computer lab, home, work and the moments that made me pay attention.
  2. The everyday choicesSunrise, outdoor breaks, wired devices and a cool, dark bedroom.
  3. The invitationLearn something. Ask a question. Tell your own story if you choose. This resource is here even if you never file an RFI comment.

START WITH
WHAT YOU KNOW.

Choose what you want to share. You can start with one experience or one question, then see an example beside your answer.
