What is a cell phone? How does it work? A cell phone is a portable phone that uses a network of “base stations” or fixed antennas, that allow users to call from almost any location. The phones send and receive radio frequency signals to and from the base station. Base station antennas often are mounted on towers, but can also sit on rooftops, water towers, power poles, and other tall structures. All cell phones are tested according to government standards and cannot be marketed or sold unless they have passed these standards. What is RF? Electromagnetic radiation consists of waves of electric and magnetic energy moving together (radiating) through space. Radio waves and microwaves released by transmitting antennas are one form of electromagnetic energy. They are called “radio frequency” or “RF” energy or radiation.

The basic forces that support life in each of us are the normal ...

For ease of identification, hazards are classified based on ...
