Over a quarter‑century in EMF mitigation. Since 1998, RF Safe has blended first‑principles engineering, policy action, and real‑world education to cut unnecessary RF exposure—while charting a Light Age path with Li‑Fi indoors and smarter antennas outdoors.
Explore the ResearchRF Safe—founded in 1998 by John Coates—exists to align connectivity with biology. We reduce unnecessary RF exposure today and push federal standards and research to catch up with modern science. The end state is simple: wires where it’s easy, Li‑Fi indoors, and lower‑burden RF outdoors.
It’s not about selling gadgets; it’s about policy, design, and education. Accessories help, but systemic fixes protect everyone—especially kids.
Ultra‑thin cases designed from first principles to reduce body‑ward RF without forcing phones to boost power. No magnets. No metal loops. Shielded audio path for 5G era. The goal is simple: **distance + directionality** that works with antenna physics, not against it.
Early‑2000s RF Safe designs routed audio through hollow tubes so the ear canal sits outside the RF hot‑spot; belly bands helped shield baby bumps in high‑EMF workplaces. The point was never monopoly—teach the world how to build them right and step back once the market learned.
RF Safe champions infrared light‑based Internet in classrooms—hundreds of Mbps with no microwave bath—paired with simple tablet cases that make devices Li‑Fi‑ready. Pilots are being donated to show how quickly schools can cut indoor RF.
Portable, battery‑powered 222 nm concepts for disinfection during emergencies; and a self‑powered short/long‑wave UV detector card for everyday threat‑spotting.
RF Safe calls for removing Telecom Act Section 704 gag rules that block local health considerations in siting—and for HHS/FDA to enforce Public Law 90‑602 (“shall establish and carry out” an electronic product radiation control program) with modern research and performance standards.
RF Safe pushes to restart NTP’s RF program (which reported “clear evidence” of heart schwannomas) and to finish the FCC’s court‑ordered review of its 1990s limits—updating guidance to reflect non‑thermal harms and children’s susceptibility.
Indoors: Li‑Fi first. Outdoors: lower‑burden RF and smarter antennas. Where possible, move high‑power transmitters away from people and toward physics‑efficient placements.
Free tools compare head/body SAR across phones and explain why SAR is not a biological safety metric. The database helps users make smarter choices while advocating for better standards.
RF Safe highlights literature on oxidative stress, ion‑channel disruption, and antioxidant depletion—urging families to prefer wired setups and to discuss medication choices with their clinicians during pregnancy.
From early 2000s antenna reform efforts to a 2021 light‑networking patent, RF Safe’s filings aim to seed markets, not hoard them—blueprints for safer connectivity.
John Coates conceived an interferometric array that nulled RF toward the user while steering energy outward. In 1999 he transferred the concept for development, prioritizing public health over profit. In 2003, after advocacy that showcased user‑protective directionality, the FCC permitted directional phone antennas—a key policy step beyond a rigid isotropic mindset. Commercial twists followed, but the lesson stuck: safer designs are possible when rules allow them.
That ethos continues in RF Safe’s “Light Age” work and the commitment to place public welfare ahead of personal gain.
RF Safe engineered the first anti‑radiation cases when handsets still had external antennas. Tests in the 1990s showed why metal loops or plates placed outside the shield angle could defeat protection or trigger higher phone power. That is why RF Safe’s designs avoid gimmicks that interfere with antennas and focus on orientation, distance, and simplicity that actually reduce exposure.
RF Safe’s position: detachable covers, magnets, and metal plates in the wrong place can increase emissions by prompting the phone to boost power. We advocate honest testing on complete phones (not just raw materials) and clear consumer guidance.
From early exposure near military radar to founding RF Safe in 1998 after the loss of his first‑born daughter, Coates frames unchecked wireless as “entropic waste”—noise that scrambles the body’s bio‑electric code. The answer isn’t to abandon connectivity; it’s to engineer it wisely and to enforce laws that already say “shall” when it comes to radiation control.
Kids absorb more energy due to anatomy and development. The fastest way to lower classroom exposure is simple: remove indoor RF (tablets + routers) in favor of Li‑Fi/wires; keep outdoor RF lower‑burden and farther away.
FCC limits remain rooted in the 1990s and focus on thermal effects—ignoring modern evidence for non‑thermal biological effects (DNA damage, oxidative stress, calcium dysregulation, neurological impacts). In 2021, the D.C. Circuit faulted the FCC for failing to address evidence on long‑term exposure, children’s vulnerability, pulsation/modulation, and new tech.
Two independent bioassays—NTP and Ramazzini—reported excess heart schwannomas and brain gliomas. A WHO‑commissioned 2025 review rated these animal signals as high‑certainty. Shutting down the U.S. program after positive findings is indefensible.
Wireless policy has prioritized deployment over health. The court remand exposed this gap. We need leadership free of industry ties, modern exposure science, and transparent processes.
Section 704 blocks communities from using health concerns in siting decisions while limits remain outdated.
PL 90‑602 directs HHS/FDA to run a continuing Electronic Product Radiation Control program for devices that emit radiation—including wireless. We need a functioning program now, with research + performance standards.
Some accessories can increase exposure by triggering phone power boosts. RF Safe urges real‑phone testing, accurate marketing, and warnings for designs that interfere with antennas.
Big picture: INTERPHONE’s heaviest users showed elevated glioma risk; NTP and Ramazzini found the same tumor types without heating; a 2025 WHO project rated animal evidence for glioma and heart schwannoma as high‑certainty; hundreds of studies show oxidative‑stress/DNA‑damage pathways; registries report rising CNS tumors. Precaution isn’t panic—it’s responsible engineering.
Teenagers today exceed that “heavy” bar by hours/day. If a signal appeared at ~30 minutes/day in the 2000s, we must ask what today’s chronic uses do.
NTP: clear evidence for heart schwannomas; some evidence for gliomas; DNA damage. Ramazzini: heart schwannomas at far‑field, tower‑like levels.
Rated glioma and heart schwannoma signals as high‑certainty; benchmark‑dose modeling further anchors hazard assessment.
Meta‑analysis and cohort data support practical precautions now—shorter calls, off‑body carry, night‑time airplane mode, and Li‑Fi/wires indoors—especially for pregnancy and childhood settings.
Mechanistic reviews lay out a coherent pathway that matches tumor findings and non‑thermal experiments across hundreds of studies.
Registries integrate many drivers; a rise isn’t proof of causation—but it’s not “no signal.” The prudent course is to act while refining.
FDA‑cleared RF therapy for liver cancer uses non‑thermal signaling—evidence that low‑level fields can drive biology. Policy can’t pretend only heat matters while medicine leverages non‑thermal effects.
Demand updated exposure guidelines, restart federal research, and adopt Li‑Fi/wires indoors. Precaution is simple: distance, time, and better infrastructure.
Use RF Safe’s comparison tools to understand emissions—and why SAR is not a biology‑based safety metric. Compare devices, then reduce exposure through behavior and infrastructure.
Compare multiple models, but remember: SAR was designed around heating, not non‑thermal effects or on‑body use in low‑signal areas. Distance is the biggest lever.
Children absorb more energy due to anatomy and development. Keep devices off the body, use speaker/air‑tube, and prefer Li‑Fi/wires indoors.
Disable unused radios. Schedule Wi‑Fi off at night. Airplane mode when pocketed.
Rankings help you compare devices under standardized tests. The long‑term fix is standards and infrastructure that reduce real‑world exposure.
Stay current on science, policy, and practical ways to reduce exposure.
