The Federal Communications Commission (FCC) and Food and Drug Administration (FDA) are caught in a regulatory stalemate that has left wireless radiation safety standards unchanged since 1996, even as cell phones, 5G networks, and connected devices have become ubiquitous in American homes and schools. A federal appeals court ruled in 2021 that the FCC failed to adequately address health risks from wireless radiation, but nearly five years later, no meaningful updates have been implemented. Now, a new legal petition is forcing the issue back into the spotlight, raising questions about who is actually responsible for protecting public health from electromagnetic field (EMF) exposure.

What Happened in the 2021 Court Ruling That Changed Everything?

In 2021, the U.S. Court of Appeals for the D.C. Circuit remanded the FCC's decision to keep its radiofrequency exposure limits unchanged from 1996. The court found that the FCC's explanation for maintaining those limits was legally inadequate. Specifically, the court said the FCC had failed to provide a reasoned explanation for its conclusion that its guidelines adequately protect against harmful effects of radiofrequency exposure unrelated to cancer.

The court's reasoning went deeper than a simple procedural complaint. The official opinion highlighted that the FCC's guidelines had not been meaningfully updated in three decades, and the agency had failed to adequately address evidence involving non-cancer health effects, impacts on children, long-term exposure patterns, radiofrequency pulsation and modulation effects, technological developments such as 5G, the ubiquity of wireless devices in daily life, and environmental harms. This was a significant acknowledgment that the regulatory framework was outdated.

Why Is the FDA Staying Silent While the FCC Remains in Charge?

The core problem is jurisdictional confusion. The FCC is a spectrum and communications agency, not a medical or toxicology agency. Yet it has become the de facto authority on wireless radiation safety limits in the United States. Meanwhile, the FDA, which has explicit legal authority over electronic product radiation under federal law, has largely deferred to the FCC and issued broad reassurances without conducting its own comprehensive health assessment.

Under Public Law 90-602, enacted in 1968 and codified in the Federal Food, Drug, and Cosmetic Act, the FDA and the Department of Health and Human Services (HHS) are legally responsible for establishing and carrying out an electronic product radiation-control program to protect public health and safety. This program is supposed to include developing performance standards, supporting research, evaluating emissions and exposure conditions, developing procedures to minimize exposure, and making public information available about hazards and controls. Yet this mandate has been largely dormant for decades.

In January 2026, Reuters reported that HHS would launch a study on cellphone radiation and that the FDA had removed older webpages stating that cellphones are not dangerous. The FDA stated that it removed old conclusions while the department undertook work to identify knowledge gaps involving electromagnetic radiation and modern technologies. However, the FDA's current public cell-phone page still contains broad reassurance language, creating confusion about the agency's actual position on wireless radiation safety.

What Devices and Exposures Are We Talking About?

The regulatory gap affects a wide range of everyday technology. The devices and infrastructure in question include cell phones, Wi-Fi routers, cell towers, smart devices, Bluetooth accessories, wearables, tablets, smart meters, and 5G infrastructure. These technologies have expanded into every part of daily life, from classrooms to bedrooms, under a regulatory framework that was designed around a single, narrow question: does radiofrequency radiation heat tissue too much?

This thermal-only approach ignores decades of research suggesting that non-thermal biological effects may occur at lower exposure levels. The science has evolved significantly since 1996, but the regulatory limits have not.

How to Understand the Legal and Regulatory Landscape

• The FCC's Role: The FCC licenses spectrum, manages communications infrastructure, promotes deployment, and auctions access to the public airwaves. It is not equipped to evaluate toxicology, pediatric health, oncology, or reproductive health impacts of wireless radiation exposure.
• The FDA's Responsibility: Under federal law, the FDA is responsible for collecting, analyzing, and making available scientific information about hazards and control of electronic-product radiation. The agency shares regulatory responsibilities for cell phones with the FCC and is supposed to provide scientific input and expertise on radiofrequency energy.
• The WHO and ICNIRP Influence: The FCC has relied on guidelines from the World Health Organization (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP), an international standards body. However, the independence and scientific rigor of ICNIRP have come under serious question, and public health cannot be outsourced to an international body whose independence is now under scrutiny.
• The Congressional Mandate: Public Law 90-602 was written specifically to address situations where a technology becomes widespread, exposure becomes unavoidable, and the public needs federal health protection before preventable harm becomes normalized. Congress created this legal framework, and it remains in force today.

What Is the New Legal Challenge Asking For?

Children's Health Defense has filed a new federal case seeking to force the FCC to comply with the 2021 D.C. Circuit remand. The petition asks the U.S. Court of Appeals for the D.C. Circuit to issue a writ of mandamus, a legal order directing the FCC to comply with the court's previous ruling within 90 days, to provide a 45-day status update, and to stop moving forward with wireless-infrastructure acceleration initiatives until the agency complies with the court's order.

This is not a minor procedural fight. It is a major public-health accountability issue. The underlying problem is that the country has continued building, deploying, authorizing, and normalizing wireless exposure while the underlying health-protection framework remains legally and scientifically unresolved. Regulatory expansion without regulatory accountability creates a situation where the public bears the risk while agencies avoid responsibility.

What Should Congress Do About This?

Advocates argue that Congress must enforce Public Law 90-602 and demand that federal law be followed. The next FDA Commissioner should be required to explain, on the record, how the FDA will enforce its statutory duties regarding electronic product radiation. Senators should not confirm another FDA leader who treats wireless radiation as someone else's problem, according to this perspective.

The argument is not anti-technology. Rather, it is pro-health, pro-science, and pro-accountability. The issue is straightforward: public health cannot be outsourced to a spectrum regulator, a telecom-friendly standards network, or an international body whose independence is now under serious question. The FCC is not a medical agency, the WHO is not beyond scrutiny, and ICNIRP is not an independent substitute for American law.

The FDA cannot continue to issue or tolerate public-facing assurances that outrun the evidence while the agency's own statutory radiation-control responsibilities sit in the background. If the FCC relies on federal health agencies to justify radiofrequency exposure limits, then the FDA and HHS must provide a current, medically defensible, transparent health-risk assessment. Circular regulation, where the FCC stands behind the FDA while the FDA stands behind the FCC, is not public-health protection.

The 2021 court ruling exposed a fundamental problem in how the United States regulates wireless radiation. The question now is whether Congress will act to resolve it, or whether the regulatory stalemate will continue while technology deployment accelerates and exposure becomes even more ubiquitous.
