Cell phones operate with radio frequencies,a form. of energy located on the electromagnetic spectrum between FM radio waves and the waves used in microwave ovens,radar,and satellite stations.Cell phones do not emit ionizing radiation,the type that damages DNA and is known to have the ability to cause cancer.
Cell phone technology works on a system of geographically separated zones called"cells".Each cell has its own "base station" that both receives and emits radio waves.When a call is placed from a cell phone,a signal is sent from the cell phone antenna to that cell's base station antenna.The base station responds to the cell phone signal by assigning the phone an available RF channel.When the RF channel is assigned,radio signals are simultaneously received and transmitted,allowing voice information to be carried between the cell phone and the base.The base station transfers the call to a switching centre, where the call can be transferred to a local telephone carrier or another cell phone.
