Cell Phone Radiation Tests & Shielding Materials

A nice video showing how a Tri-Field meter operates, testing an older GSM cell phone for radiation levels, and evaluating different types of materials which can be used for blocking the microwave energy which is emitted by the cell phone. Newer GSM smartphones test very similar to what's shown in this video. 5G uses much higher frequencies in the 25 to 50GHz range!
