Significant evidence from emerging studies published in the peer-reviewed literature suggest dire health threats may result from radio-frequencies (RF) commonly emitted from cell phones, WiFi, TV broadcast antennas, etc. (Rev Environ Health. 206 Sep 1;31(3):363-97. Also: Head Neck. 2018 May 13. doi: 10.1002/hed.25210. And: Cell Biochem Biophys. 2014 Nov;70(2):983-91.). Certain techniques and materials are now commercially available to help check RF risks.
