Introduction
A 2025 review article published in the peer-reviewed journal Frontiers in Public Health examines the current U.S. regulatory framework governing radiofrequency radiation (RFR) exposure limits for wireless technologies.
The paper, titled: “U.S. policy on wireless technologies and public health protection: regulatory gaps and proposed reforms” analyzes how federal exposure standards are set, which agencies hold oversight responsibility, and where regulatory gaps may exist.

What the Paper Examines
According to the authors, the current U.S. framework:
- Has not updated federal exposure limits since 1996
- Focuses primarily on protection against short-term thermal effects
- Does not require pre-market safety testing for wireless devices
- Lacks structured post-market surveillance
- Does not include environmental monitoring requirements
- Contains no specific safeguards for children or pregnancy
The paper also discusses occupational exposure, wildlife impacts (including pollinators), and international regulatory comparisons.
Regulatory Structure
Since 1996, the Federal Communications Commission (FCC) has held jurisdiction over wireless exposure limits, although it is primarily a licensing and engineering agency rather than a public health body.
The authors describe:
- The absence of active federal non-ionizing radiation research programs
- Limited monitoring and enforcement mechanisms
- The role of federal preemption in limiting local authority
2021 Federal Court Decision
In 2021, the United States Court of Appeals for the District of Columbia Circuit ruled that the FCC had not adequately explained its decision to retain its 1996 exposure limits following a 2019 review.
The court directed the agency to provide a reasoned explanation addressing evidence related to:
- Cancer
- Neurological impacts
- Environmental effects
- Impacts on children
The paper references this decision as part of its broader regulatory analysis.
Why This Matters Locally
Exposure limits are set at the federal level. Local governments — including Montgomery County, Maryland — must operate within those federal standards when reviewing wireless infrastructure applications.
If federal standards are under review, unchanged, or contested, local decision-makers are still bound by those limits under federal preemption law.
This regulatory structure shapes how zoning amendments, small cell deployments, and infrastructure siting decisions unfold at the local level.
