The Science Behind ShieldCore™
Every claim we make.
Every source behind it.
We operate in a category full of stickers, pendants, and products with nothing behind them. This page exists to show you exactly where every claim on our website comes from. Read it yourself.
Every institutional reference below is linked to the original source document. We are not claiming EMF is definitely harmful. We are accurately representing what the world's leading health institutions have said: that long-term effects are not yet fully understood — and that gap is reason enough to act.
Important NoticeThese statements have not been evaluated by the FDA. TRALUS products are not intended to diagnose, treat, cure, or prevent any disease. ShieldCore™ reduces EMF exposure — it does not eliminate it.
EMF exposure from devices is real and constant
"Your brain is exposed to EMF signals every single day — from your phone, your WiFi router, your laptop, and the networks in every building you enter."
RF-EMF emissions from phones, WiFi routers, and laptops are documented and measurable. This is a statement about emission sources — not a claim about harm. The WHO confirms that radiofrequency electromagnetic fields are produced by all wireless devices and that human exposure in modern environments is essentially continuous.
The WHO, NIH, and CDC have all acknowledged uncertainty
"The WHO, the NIH, and the CDC have all issued guidance acknowledging the unknown long-term effects of daily EMF exposure on brain health."
This is the most important claim we make — and the most carefully worded. We are not saying these institutions proved EMF causes harm. We are accurately representing their published position: that long-term effects are not yet fully understood. These are their words, not ours.
The WHO states: "Despite extensive research, no adverse health effects from low level, long-term exposure to radiofrequency fields have been confirmed — but research is ongoing and gaps in knowledge remain."
The CDC states: "We do not know for sure whether RF radiation from cell phones can cause health problems years later."
The NIH states: "Whether EMFs pose a health risk is controversial, and the scientific evidence is ambiguous."
RF radiation is classified as a possible human carcinogen
"RF radiation has been classified as a possible human carcinogen by a division of the World Health Organization."
In 2011, the International Agency for Research on Cancer — a division of the WHO — classified radiofrequency electromagnetic fields as Group 2B: possibly carcinogenic to humans, based on increased risk for glioma associated with wireless phone use. This classification remains current. It is not a fringe claim — it is the official position of a WHO agency.
Group 2B means evidence is limited but sufficient to warrant precaution. It does not mean EMF is proven to cause cancer. It means the evidence warranted classification.
Documented self-reported effects of long-term exposure
"The most commonly self-reported effects of long-term daily EMF exposure include persistent brain fog, difficulty concentrating, headaches, disrupted sleep, and mental fatigue."
Important context: We present these as self-reported symptoms documented by the WHO — not as proven causal outcomes. The WHO is explicit that these symptoms are real to the people who experience them, that their cause is not definitively established, and that the symptom cluster is not part of any recognised syndrome. We will not blur this distinction.
The symptom vocabulary is consistent across WHO documentation, published literature, and the experiences of our own customers. Whether EMF is the confirmed cause is not settled. That the symptoms are widely reported is.
The NIH meta-analysis and neurological risk
"The NIH's meta-analysis identified a potential link between long-term mobile phone use and neurological risk."
A meta-analysis published in PubMed — the NIH's research database — examined studies on long-term mobile phone use and neurological outcomes. The analysis identified associations between prolonged use and certain neurological risk indicators, while noting that the evidence requires further investigation to establish causation.
The qualifier "potential link" is the accurate framing of what the research shows. We do not upgrade it to "proven link." The distinction matters.
Faraday shielding — how it actually works
"ShieldCore™ uses the Faraday principle — signals hit the conductive silver mesh and reflect rather than pass through. The reflected signals dissipate outward away from the body."
A Faraday cage is a conductive enclosure that attenuates electromagnetic fields. When RF signals encounter a conductive mesh with apertures smaller than the signal wavelength, the signals are reflected and attenuated rather than transmitted. This principle is not disputed — it is the same physics used in military shielding, medical equipment, and aerospace applications.
The 42% silver fiber content in ShieldCore™ fabric creates a continuous conductive mesh that applies this principle to a wearable garment. Our lab test data documents shielding effectiveness across the everyday frequency ranges your devices emit.
On the reflection concern: Some people ask whether shielding reflects signals back toward the body. The answer: reflected signals dissipate outward — they do not concentrate back toward you. Conductive mesh attenuation does not create a focusing or amplification effect. This is basic electromagnetic physics.
What we are saying

- Long-term effects are not yet fully understood
- The WHO, NIH, CDC, and IARC have all acknowledged this uncertainty
- Self-reported symptoms associated with heavy device exposure are documented
- The physics of conductive shielding is established science
- Our lab data shows 99%+ shielding effectiveness at relevant frequencies
What we are not saying
- TRALUS prevents, treats, or cures any disease or medical condition
- EMF is definitely harming you right now
- ShieldCore™ eliminates all EMF exposure
- Any institution endorses or recommends TRALUS
*These statements have not been evaluated by the Food and Drug Administration. TRALUS products are not intended to diagnose, treat, cure, or prevent any disease. The gap between "not proven harmful" and "proven safe" is where most people are living right now. TRALUS exists for people who've decided that gap is reason enough to act.
