Frequently asked questions
Is RadiHalt better than DefenderShield?
"Better" depends on what you need. DefenderShield sells EMF Protection Anti-Radiation Blanket at $199.99 – $399.99 — best suited for whole-body bedding coverage and large lap throws. RadiHalt is an 18" x 18" copper-nickel lap shield at $89.99, purpose-built for daily, portable point-of-use shielding over a laptop or lap. They solve different jobs, so the honest answer is: pick the one whose form factor matches how you'll actually use it.
What is RadiHalt's blanket made of?
RadiHalt uses a copper-nickel alloy fabric — a continuous metallic weave that creates a Faraday-effect barrier. We disclose the material publicly because we believe buyers deserve to know exactly what's in their shielding product.
What is DefenderShield's blanket made of?
DefenderShield's EMF Protection Anti-Radiation Blanket uses 70% bamboo / 30% cotton outer with two layers of nickel-copper shielding fabric.
Does RadiHalt have published lab test results?
Not yet. We disclose the material composition (copper-nickel alloy) publicly, and the Faraday-effect of a continuous metallic weave is well-established physics. We have not yet published an independent third-party dB attenuation report. Where competitors do publish such reports, we credit them in this comparison.
