How the silver-lined cap works:

1. The radiation source hits the high silver inner layer.
2. 99.995% of this radiation is reflected off the material and away from you.
3. Shielding/protective capacity from the fabric means that only 0.005% of the initial radiation gets through to the body and is absorbed into the body.
4. The small electrical field resulting from the 0.005% radiation is conducted by the body. Even without grounding, this electrical field level is insufficient to power the tiniest watch battery, less than 100th of a volt.
5. If a person were standing in the presence of a WiFi modem or cell tower, they could absorb over 1,000,000 times the level of microwave compared to wearing a protective shielding product like this cap.
