HHS Opens Public Inquiry Into Wireless Radiation and Health

The U.S. Department of Health and Human Services (HHS) has opened a public request for information on radiofrequency and wireless radiation exposure and human health. The notice, signed by Secretary Robert F. Kennedy, Jr. and published in the Federal Register on September 21, 2026, asks researchers, clinicians, industry and members of the public to submit evidence and experiences by October 21, 2026.

It is a call for input, not a rule, a warning or a finding. What the notice does show is which questions the department wants answered, and how it frames them.

What HHS is asking for

The notice covers electromagnetic fields (EMFs) broadly. It describes them as energy fields produced by moving electrically charged particles and electrical currents, spanning low radiofrequency (RF) associated with power systems and household appliances up to the higher RF and microwave exposures associated with wireless communication technologies. HHS says it will use the responses to:

• assess the current state of the scientific evidence on RF/EMF exposure and health outcomes;
• compare existing domestic and international safety standards and regulatory approaches;
• identify research gaps and priority areas for future study;
• inform recommendations for policymakers, public health stakeholders, families, schools and communities.

The notice says the department’s emphasis is on environmental factors that may affect health, “particularly among children and other potentially vulnerable populations.” It also states that public concern has increased, in particular about children, schools and long-term cumulative exposure, and that the scientific literature is “extensive, technically complex, and not always easy for policymakers or public health stakeholders to interpret.”

The questions, in five groups

The notice lists its questions under five headings, followed by an open-ended item for any additional evidence:

• Public experiences and reported potential adverse health effects. Individuals and families are invited to describe symptoms they believe may be linked to RF/EMF, including the source (mobile phones, Wi-Fi, smart meters, wearables and others), timing, medical evaluation and whether reducing exposure changed anything. Clinicians and researchers are asked about patterns they have observed and how exposure was assessed.
• Exposure standards and risk assessment. Which national and international standards federal agencies should consider, and whether a classification system should account for factors such as frequency, power density, specific absorption rate (SAR), modulation, duration and distance from the body.
• Measuring exposure and public health surveillance. Which methods can characterize individual and population exposure, and whether disease registries, cohort studies, biomonitoring or adverse-event reporting could be used or built. It also asks whether risk evaluation should differ for children, pregnant women, older adults, people with implanted medical devices, workers and people with preexisting conditions.
• Existing evidence. Evidence on effects “at levels below current federal exposure limits,” on effects “caused by current exposure limits,” and on how technologies from 5G and Wi-Fi to satellite communications, smart meters and wireless medical devices affect cumulative exposure. Questions also cover wireless infrastructure such as antenna density and small-cell deployment near homes, schools and workplaces.
• Federal research priorities. The largest research gaps, and how the FDA, the National Institutes of Health and the Centers for Disease Control and Prevention could coordinate.

What this document does and does not establish

The notice is a solicitation. It does not present new data, and it does not say that any exposure level is harmful. Several questions are phrased with “potential” and “if any,” and one asks respondents to “clearly distinguish established evidence from emerging findings and areas of uncertainty.” The department also asks each respondent to say whether their answer rests on peer-reviewed research, government reports, industry data, clinical observations or other sources.

That last point matters for how the results are read later. The first heading invites personal accounts of symptoms. Personal accounts and clinical observations can point to questions worth studying, but they cannot show cause and effect by themselves, and the notice does not say how they will be weighed against controlled research. Comments are voluntary, may be anonymous, and become public on regulations.gov.

The notice states that it “should not be construed as a policy” and that the government is not obligated to act on any idea submitted. It adds that responses “may be reflected in future solicitation(s) or policies.”

What remains unknown

• What comes next. The notice gives no timetable for any report, guidance or rulemaking after the comment period closes.
• How evidence will be weighed. No methodology for reviewing submissions is described.
• Whether any standard would change. The notice asks whether current limits should be revisited but announces no change.
• Which agency leads. It lists possible roles for the FDA, NIH and CDC without assigning any.

Why it matters

Exposure limits for wireless devices and infrastructure affect manufacturers, telecommunications providers, schools and local governments, and the questions on disclosure and on sensitive populations suggest HHS is considering more than research alone. Whether the process leads to new research funding, consumer guidance or regulatory proposals will depend on what the department does with the responses. For now, the practical effect is an open docket: anyone with relevant data can file it, and what is filed will be publicly visible.

Comments can be submitted through regulations.gov under docket HHS-OASH-2026-0397 until October 21, 2026.
