Electromagnetic sensor

The Airborne Electromagnetic and magnetic (AEM) transmitter generates a magnetic field that is lower than 1/100th of the accepted general public exposure level across all frequencies. The same AEM surveys have been conducted in other locations throughout the US with no reported ill effects to humans or animals. This project does not pose a risk to health or safety. The very low level of magnetic exposure is about the same as standing one foot from a toaster, as shown on the figure, and the technology works in a manner similar to wireless phone charges (though at a different scale).
