We were skeptical about the new 5G phones which will still mostly operate on 5G to little benefit no matter what the telecom ads tell you. Now we find the exposure seems to exceed recognized limits for safety:
A new peer-reviewed paper, “Human Electromagnetic Field Exposure in 5G at 28 GHz,” questions the safety of exposure to 5G millimeter waves. The authors found in a simulation study that use of a 5G cell phone at 28 GHz could exceed ICNIRP (i.e. international) radio frequency exposure limits when held at 8 centimeters (i.e., 3 inches) or closer to the head or body. Whereas the ICNRIP exposure limit for the Specific Absorption Rate (SAR) is 2.0 watts per kilogram averaged over 10 grams of tissue, the FCC limit is 2-3 times more conservative, namely the SAR limit is 1.6 watts per kilogram averaged over only 1 gram of tissue. This means compliance with the FCC exposure limit would require a greater separation distance from the body than 8 centimeters in the U.S.
