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 heat-only limits from the 1990s or designs 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.
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. Phones compensate with higher power. |
| 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, enforce existing health-agency mandates, and pilot light-based indoor networks. Copy the letter below or write your own.
Tip: Request Li-Fi pilots for classrooms/offices, clear usage guidance (orientation/distance), and a review of siting rules that block health evidence.
Evidence & References
SAR is a thermal compliance number — not a biological safety seal
Why “lowest SAR” ≠ safest; what real use adds (modulation, duty-cycle, low-signal power ramps, simultaneous radios, detuning). See the SAR explainer and tools.
FCC remand (EHT v. FCC, 2021)
The D.C. Circuit found the FCC’s decision to keep 1996 limits “arbitrary and capricious” for failing to address non-cancer harms, children, and modern signals, and sent it back to the agency.
Docs & docket on FCC site (opinion excerpts included).
Section 704 preemption
47 U.S.C. § 332(c)(7)(B)(iv) preempts localities from denying antennas “on the basis of the environmental effects of RF emissions” if FCC limits are met — binding communities to 1990s, heat-based limits.
Public Law 90-602 (Electronic Product Radiation Control)
HHS/FDA “shall” run a radiation-control program including research, standards, and public information (21 U.S.C. §360ii, §360kk).
Large bioassays: NTP & Ramazzini
- NTP TR-595: cell-phone-style RFR, “clear evidence” of malignant heart schwannomas in male rats; brain signals also reported.
- Ramazzini (far-field/base-station-like): increased heart schwannomas at environmental-level exposures.
WHO 2023–2025 reviews & debate
WHO-commissioned SRs (Environment International) and critiques (e.g., Melnick 2025) reflect ongoing scientific debate; animal SR rated “high certainty” for heart schwannomas, “moderate” for brain gliomas.
Light-First feasibility (Li-Fi standard 802.11bb, 2023)
IEEE ratified 802.11bb, specifying infrared light communications (Li-Fi) with high data rates — a practical path to reduce indoor RF load.

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 often respond by increasing transmit power to hold the link.
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
- Policy: U.S. limits remain thermal-only (1996); localities face §704 preemption.
- Bioassays: NTP TR-595 & Ramazzini report tumor signals (heart schwannomas; brain tumors).
- Debate: WHO-commissioned SRs (2023–2025) and critiques show active scientific debate.
- Path forward: Light-First indoors (Li-Fi 802.11bb), smarter RF outdoors, modernized federal guidance.
