    Abstract: Mobile devices may minimize the radiation exposure to users by controlling the distance between the user, specifically the head, and the mobile device to a minimum distance. The reduction in exposure is realized due to the operation of the Inverse Square Rule on electromagnetic signal from the mobile device recognizing there is a steep fall off of signal strength resultant from increased distance between the head of the user and the source of the signal. Embodiments increase and maintain operational distance between the user and the broadcast device to reduce signal absorption. Embodiments enforce the operational distance with physical barriers preventing the distance from being reduced. Thus maintaining a minimum distance between the user and the transmitter may have a dramatic practical effect.
