The Issue
With the growing popularity of hand-held cellular phones (or cell phones), questions have been raised about the safety of being exposed to the radiofrequency (RF) electromagnetic energy they emit. Some members of the public have also expressed concern about the possible health effects caused by living near cellular base stations, which are often called cell phone towers.
Background
Cell phones are portable devices that transmit and receive radio signals from a network of fixed, low-power, base stations. The base stations are usually located on rooftops, towers and utility poles. The transmitting power of a cell phone varies, depending on the type of network and its distance from the base station. The power generally increases the further you move away from the nearest base station.
