Products can help you use tech more safely — policy fixes the problem.
A well-engineered case can lower near-body exposure in real use (by placement and orientation), but it can’t fix outdated, thermal-only limits or stop design mistakes that make phones transmit harder. The real solution is policy reform and light-based indoor connectivity — while we teach better habits today.
No percentage claims. Real-world reduction = orientation + antenna behavior + duty cycle.
Until standards address modulation, pulses, cumulative dose and kids, the market shifts the true costs onto families.
Accessories can reduce dose in use — but they can’t correct regulatory gaps that allow risky defaults to persist.
Move indoor connectivity toward light (Li-Fi / optical) and seat RF health oversight where it belongs; use cases as training wheels, not talismans.
Place shield between body & phone in calls/pocket
Keep antennas efficient; avoid power ramp-ups
Avoid large unshielded ear-side gaps
Let users verify a real shield path
Misleading marketing vs. first-principles design
| Misleading claim or feature | TruthCase™ principle |
|---|---|
| “99% protection everywhere” from a fabric swatch | Orientation & duty cycle matter. Put the shield between you & the phone; teach habits. |
| Metal loops, magnet plates, thick 360° wraps | Don’t detune antennas. Keep radios efficient to avoid automatic power increases. |
| Large unshielded ear-side speaker hole | Maintain continuity at the ear. No big aperture where you need reduction most. |
| Vague or no usage guidance | Teach calls, pocket orientation, distance, and night discipline. |
Design that obeys physics + honest guidance beats slogans.
TruthScore — quick red-flag check
Tick any that apply to your current case, then read the guidance below.
Ohmmeter verification — proof you can touch
- Set any basic ohmmeter to continuity (beep) mode.
- Touch one lead to the access point near the ear-side aperture inside the front cover.
- Touch the other lead to a second point on the shield layer.
- Continuity = a real conductive shield path.
A transparent way to prove there’s more than marketing fabric in the cover.
What a good case can (and can’t) do
Products are training wheels. Policy is the solution.
Ask for modern guidance, enforcement of existing health authority mandates, and light-based indoor networks where feasible. Copy the letter below or write your own.
Tip: Consider requesting Li-Fi pilots for classrooms/offices, clear phone-use guidance (orientation/distance), and a review of siting rules that currently prevent communities from considering health evidence.
Quick answers
Does it “block 99%”?
No slogans. Real-world exposure depends on placement, antenna behavior, and duty cycle — not a fabric number.
Why avoid magnets/loops/plates?
They can detune antennas. Phones respond by increasing transmit power to hold the link — the opposite of what you want.
Is TruthCase™ the same as QuantaCase®?
TruthCase™ is QuantaCase® by RF SAFE — built to avoid antenna mistakes, enable proper use, and lead the policy change we actually need.
What about kids?
Teach distance (speaker or wired), avoid pockets, shorten on-head calls, and keep phones off nightstands near heads.
Evidence at a glance
- Epidemiology: High-use patterns show elevated glioma risk in several studies.
- Animal bioassays: Large studies have reported tumor signals at non-thermal levels.
- Mechanism: Pulsed, polarized signals can perturb calcium signaling and oxidative stress pathways.
- Policy: U.S. limits remain thermal-only (1996); communities face siting constraints under federal preemption.
