These studies collectively challenge outdated FCC guidelines and call for updated safety standards that recognize non-thermal impacts. Unfortunately, research has been halted, limiting public awareness and blocking medical advancements.
2026 EPA‑method risk assessment · FCC Docket 13‑84 is open for public comment
On September 11, 2026, the FCC released Public Notice DA‑26‑971 in ET Docket No. 13‑84, seeking public comment on the radiofrequency-exposure issues returned to the agency by the D.C. Circuit in 2021. The notice followed renewed legal action by Environmental Health Trust, Children’s Health Defense, and individual petitioners seeking a response to the court’s remand. This proceeding is not a new safety standard. It is the public’s opportunity to build the record from which a modern standard must be made.
Melnick and Moskowitz estimate that the current public whole-body limit can be 15 to 900 times above exposure levels associated with a one-in-100,000 excess cancer risk, depending on daily exposure duration.
The same EPA-method assessment estimates that the current limit is approximately 8 to 24 times above levels intended to protect sperm count, sperm vitality, and testosterone.
The controlling limits remain rooted in short-term thermal injury, while chronic exposure, modulation, vulnerable life stages, and non-thermal endpoints require direct evaluation.
The FCC is accepting comments on the unresolved issues identified by the court. Children, long-term exposure, pulsation and modulation, device testing, and environmental effects belong in that record.
Ronald L. Melnick, who designed the National Toxicology Program radiofrequency studies, and Joel M. Moskowitz applied standard U.S. Environmental Protection Agency risk-assessment methods to animal cancer and male-reproductive data. They estimated cancer-risk reference levels of approximately 0.8 to 5 milliwatts per kilogram and male-reproductive reference levels of approximately 3.3 to 10 milliwatts per kilogram, compared with the FCC/ICNIRP general-public whole-body limit of 80 milliwatts per kilogram.
The largest cancer multiple is an all-day-exposure scenario; it is not one universal factor for every person or device. At eight hours per day, the authors estimate that the current limit is at least about 200 times too high for the cancer-risk target they used. That qualification makes the result more informative, not less alarming: a limit presented to the public as protective changes by orders of magnitude when lifetime risk and exposure duration replace acute heating as the question.

Open the FCC Express Comment form, enter proceeding 13‑84, and submit a clear, factual comment. Ask the Commission to address the 2021 remand directly: long-term and non-thermal effects, risks to children, the characteristics of pulsed and modulated signals, realistic device-use conditions, rapidly expanding wireless infrastructure, and environmental effects. Personal experience can explain why the issue matters, but specific studies, precise requests, and accurate citations make the administrative record harder to disregard.
RF Safe is a public-health advocacy and research project, not a product company. It has worked at the forefront of radiofrequency safety since the 1990s with one purpose: protect children and future generations from avoidable exposure by bringing policy into alignment with modern physics, biology, toxicology, and realistic patterns of use.
Founded in 1998 by John Coates, RF Safe grew out of personal loss. After his firstborn daughter, Angel Leigh, died with a neural-tube defect in 1995, Coates began investigating preventable environmental influences on development and redirected his engineering work toward reducing unnecessary radiofrequency exposure. That mission has continued for more than three decades.
RF Safe stopped selling consumer products in 2020. Its historical engineering designs remain open for public use, but the work today is centered on evidence, public education, and policy. That includes a research library of more than 6,500 studies, open SAR comparison tools, a mechanistic S4–Mito–Spin research framework, and a policy program focused on enforceable exposure reduction.
Personal precautions can lower an individual exposure, but they cannot repair an obsolete national standard or redesign a school network. RF Safe therefore calls for four structural changes: modernize the FCC limits; reinvigorate the federal research and public-health duties established by Public Law 90‑602; repeal or reform the health-based preemption in Section 704; and require Li‑Fi compatibility so schools, homes, healthcare facilities, and workplaces can move routine indoor data traffic from microwave radiofrequency carriers to localized optical links.
No sticker, chip, case, pendant, or shielding accessory can substitute for protective standards and lower-exposure infrastructure. RF Safe has not sold consumer products since 2020, but it does evaluate designs and technologies and may identify them as RF Safe Approved when they satisfy transparent, physics-first exposure-reduction principles. This can include optical alternatives such as Li‑Fi and case designs developed through decades of RF Safe research and testing, including QuantaCase™ and TruthCase™, which were engineered to avoid recognized design red flags.
RF Safe approval is not a claim of zero exposure, medical protection, or a substitute for safer policy. It indicates that a product’s stated function is consistent with known physics, its limitations are communicated honestly, and its complete design avoids foreseeable ways of making exposure worse. For phone cases, that means preserving antenna performance, avoiding unnecessary metal or magnetic structures near antenna systems, teaching correct shielding orientation, and evaluating the functioning phone rather than merely testing a detached fabric sample. Claims should be supported by realistic system-level testing across relevant frequency bands, signal conditions, and user positions.
Heating is a real interaction, but it is not the only biologically relevant question. Living cells encode information in membrane voltage, calcium pulse timing, mitochondrial electrochemical gradients, redox state, and spin-dependent reaction probabilities. The RF Safe framework organizes three plausible receiving and amplifying layers:
These pathways converge on what RF Safe calls bioelectrical dissonance: repeated perturbations that arrive faster than a biological system can correctly terminate, repair, and recover. The predicted result is low-fidelity biology—not a single disease unique to RF exposure, but a control-layer state in which timing, repair, differentiation, mitochondrial quality control, and tumor suppression become less precise. In that state, rare failures can become less rare and age-associated failures can move earlier in life. Genetics, air pollution, nutrition, infection, stress, pharmaceuticals, and other exposures can contribute to the same recovery burden; radiofrequency exposure should be evaluated as a potentially modifiable co-contributor, not dismissed because biology is multifactorial.
This framework generates measurable predictions: waveform-dependent changes should appear first in ion-channel behavior, calcium dynamics, redox chemistry, mitochondrial membrane potential, or recovery kinetics, and only later in persistent functional outcomes. That is the research program a modern exposure standard should encourage. Explore the S4–Mito–Spin overview and diagrams.
The work connects public participation, biological mechanism, exposure literacy, and safer infrastructure. Each is necessary; none is a substitute for the others.

The controlling FCC radiofrequency limits date to 1996 and are organized around avoiding excessive short-term heating and acute stimulation. They were not derived as lifetime cancer or reproductive-toxicity standards, and they do not directly regulate many biological variables now central to RF research: chronic duration, pulse structure, developmental timing, recovery, and interactions among multiple transmitters.
In Environmental Health Trust et al. v. FCC, the D.C. Circuit held that the agency had not provided a reasoned explanation for retaining its limits with respect to non-cancer effects. The court remanded the matter and directed the FCC to address evidence concerning children, long-term exposure, signal pulsation and modulation, rapidly changing wireless use, testing procedures, and environmental effects. The ruling did not calculate a replacement limit; it required the agency to confront the record it had not adequately explained.
The FCC must complete the remand transparently, disclose how it weighs conflicting evidence, use independent health expertise, and replace acute heating limits with standards that protect across a lifetime. Until that process is complete, agencies should adopt precautionary exposure-reduction guidance, especially for children, pregnancy, schools, and chronic near-body use.
The National Toxicology Program completed one of the largest controlled radiofrequency animal studies ever conducted, then discontinued further cell-phone-RF work. Ending follow-up after a positive cancer signal leaves essential questions about dose, waveform, developmental timing, susceptibility, and replication unresolved.
Restore a long-term, publicly funded RF research program with preregistered protocols, independent exposure engineering, open data, blinded pathology, modern 4G/5G and Wi-Fi waveforms, developmental cohorts, reproductive endpoints, and direct replication of positive findings.
The FCC is a communications regulator, not a public-health research agency, yet its limits determine what the public is told is acceptable. Confidence collapses when standard-setting bodies, advisory groups, and review teams are dominated by overlapping professional networks without rigorous conflict-of-interest safeguards or visible consideration of dissenting evidence.
Place the health-risk assessment under agencies with statutory public-health competence, require genuinely independent multidisciplinary panels, preserve minority scientific reports, and subject the final standard to periodic review as technology and evidence change.
Section 704 of the Telecommunications Act preserves some local zoning authority but bars state and local regulation of wireless-facility placement based on the environmental effects of RF emissions when a facility complies with FCC regulations. That preemption makes the adequacy of the federal limit decisive: communities cannot use health-based siting authority to compensate when the national standard is obsolete.
Repeal or reform the health-based preemption in Section 704, restore meaningful local participation, and require that siting decisions consider cumulative exposure, schools, childcare settings, healthcare facilities, and lower-RF alternatives while preserving reliable communications and emergency service.
The Radiation Control for Health and Safety Act of 1968, commonly known as Public Law 90‑602, established a federal program to protect the public from unnecessary electronic-product radiation. Its research, evaluation, information, and control responsibilities are directly relevant to phones, tablets, routers, wearables, and other RF-emitting products.
Use the authority Congress already created. HHS and FDA should rebuild a continuous electronic-product-radiation program with adequate funding, independent laboratories, public protocols, and recurring review of new wireless technologies. RF Safe calls for:
Public Law 90‑602 supplies the institutional foundation for sustained oversight. The task now is to fund and use it in a manner proportionate to an exposure that has become continuous, personal, and nearly universal.
Many products advertise that a material blocks a high percentage of incident radiation. That statement says little about exposure from a complete, communicating device. Phones continually adjust power and select antennas in response to connection quality, frequency band, orientation, the user’s hand, and nearby materials. A shield that obstructs one path can change the radiation pattern or cause the phone to compensate with greater transmit power.
The FTC should require substantiation for RF-reduction claims, prohibit the use of raw-material attenuation tests as proof of whole-product protection, and require disclosure when a design may obstruct antennas or alter adaptive power control. Consumers should favor measures that work by basic physics: more distance, shorter active-use time, speaker mode or an appropriate wired connection, airplane mode when connectivity is unnecessary, and a strong network signal that allows a phone to use less power.
Li‑Fi carries data through modulated visible or infrared light rather than a microwave radio carrier. It is not a cure-all and does not automatically disable every radio in a device, but it can replace a substantial share of routine indoor RF traffic when equipment is designed to make optical connectivity a genuine option.
This is no longer a speculative communications concept. IEEE 802.11bb‑2023 added light communications to the 802.11 wireless-networking family. The remaining barriers are compatibility, procurement, and deployment priorities.
Require interoperable Li‑Fi capability in new phones, tablets, laptops, access points, and public procurement standards; prioritize wired and optical connections in schools and healthcare settings; provide a user-controlled hardware method to disable unnecessary RF transmitters; and fund comparative exposure, performance, accessibility, and cybersecurity testing. The goal is not to ban communication. It is to make high-speed communication possible with substantially less compulsory RF exposure.
Supporting RF Safe means supporting a public record, a research program, and a policy transition designed to protect children—not purchasing a product.
RF Safe has not sold consumer products since 2020. Its earlier TruthCase™ and QuantaCase® work remains online as an open engineering and educational archive. The design lessons are available for public use; they are not a current storefront, and RF Safe does not endorse a third-party product unless it says so explicitly.
The archive remains relevant because it teaches a durable principle: shielding claims must be evaluated as part of a live radio system. Orientation, antenna clearance, adaptive power control, distance, network quality, and user behavior matter. The lasting solution, however, is not a better accessory. It is protective law, honest testing, independent research, and infrastructure that gives the public a lower-RF choice.
The FCC is accepting comments in ET Docket 13‑84. This is the immediate action; the larger work is creating health-led standards, restoring independent research, protecting local rights, and making lower-RF infrastructure practical.
Use the FCC Express Comment form and enter proceeding 13‑84. Cite the specific evidence and remedies you want the agency to address.
Ask HHS and Congress to restore NTP-quality RF research and fully implement Public Law 90‑602.
Support repeal or reform of Section 704 so communities can consider health, cumulative exposure, and lower-RF alternatives in infrastructure decisions.
Ask schools, agencies, manufacturers, and legislators to make wired and optical networking the default wherever radiofrequency transmission is unnecessary.
The evidence base is no longer compatible with the assumption that preventing measurable tissue heating resolves the RF-health question. Controlled animal studies, human observational signals, cellular and molecular experiments, therapeutic applications, and the 2026 quantitative risk assessment converge on a public-health conclusion: biological effects beyond acute heating must be evaluated directly. Uncertainty about the size of a particular human risk is a reason to improve exposure science and reduce avoidable exposure; it is not a scientific basis for treating the 1996 limit as permanently protective.
No single study carries this case. The warning comes from convergence across independent methods and endpoints, combined with the exceptional scale and duration of modern exposure. Standards should be designed to protect vulnerable populations—especially children—before every downstream outcome can be reconstructed in humans over several decades.
Exposure limits to radiofrequency EMF do not account for cancer risk or reproductive toxicity applies standard EPA risk-assessment procedures to tumor and male-reproductive findings from laboratory animals. The comparison is with the FCC/ICNIRP public whole-body SAR limit of 0.08 watts per kilogram, or 80 milliwatts per kilogram.
Regulatory inaction poses significant risks to public health, especially for vulnerable populations such as children. Furthermore, the misclassification of RF-EMF risks has impeded the advancement of life-saving medical interventions that could harness non-thermal effects for therapeutic purposes.
These studies collectively challenge outdated FCC guidelines and call for updated safety standards that recognize non-thermal impacts. Unfortunately, research has been halted, limiting public awareness and blocking medical advancements.

FILE YOUR COMMENT IN DOCKET 13‑84The public should not have to prove a separate disease for every waveform before regulators examine whether chronic exposure is degrading the biological systems that maintain timing, repair, development, and recovery. The rare becoming less rare, and age-associated failures arriving earlier, are precisely the population-level warning pattern that the low-fidelity-biology framework asks science and policy to investigate.
