  1. Cellular phones essentially act as two-way radios that transmit and receive radio waves. Those radio waves are made of electromagnetic radiation, a combination of electric and magnetic energy that moves at the speed of light. Electromagnetic radiation can range from extremely low-frequency radiation to very high frequencies like gamma rays. How much? A cell phone typically transmits a signal of about one watt of power, although some car phones transmit at a level of about three watts.
