Plain English Summary
Researchers analyzed how electromagnetic radiation from wireless devices is absorbed differently in real human tissue compared to the simplified liquid models used in safety testing. They found that the layered structure of human tissue - particularly fat layers under the skin - can increase radiation absorption by up to 3 times more than current testing methods predict. This means that official safety assessments may significantly underestimate how much radiation your body actually absorbs from phones and other wireless devices.
Why This Matters
This research exposes a fundamental flaw in how we test wireless device safety. The science demonstrates that current compliance testing uses oversimplified models that don't account for the complex, layered structure of human tissue. What this means for you is that the SAR (Specific Absorption Rate) values listed for your phone may underestimate actual absorption by up to 300 percent. The reality is that fat layers create standing wave effects and concentrated energy absorption in skin tissue that homogeneous testing liquids simply cannot replicate. This finding adds to growing evidence that regulatory testing protocols are inadequate for protecting public health, particularly as we're exposed to an ever-expanding range of frequencies from new wireless technologies.
