Research conducted by the Federal Communications Commission (FCC), the Electric Power Research Institute, the Utilities Telecom Council and others has found no negative health impacts from digital meters that send information via a wireless communications network. The radio frequencies (RF) emitted by digital meters fall well below the maximum recommended in federal guidelines.
The following information is from the American Cancer Society: “How much RF energy that people are exposed to from the smart meter depends on how far they are from the smart meter antenna and how the smart meter sends its signal. The frequency and power of the RF waves given off by a smart meter are similar to that of a typical cell phone, cordless phone, or residential Wi-Fi router. Smart meters typically send and receive short messages about 1 percent of the time. Because the smart meter antenna usually is located outside the home, people are much farther away from the source of RF waves than some other possible sources of exposure to RF radiation, such as personal cell phones and cordless phones. In addition, walls between the person and the smart meter’s antenna further reduce the amount of RF energy exposure. This means that the amount of RF radiation that someone would be exposed to from a smart meter is probably much lower than the amount that they would be exposed to from other sources.”
