What is Radio Frequency (RF) radiation from mobile phones?
There are currently over 195 million mobile phones in use around the world and that number is expected to exceed the 450 million mark by the year 2,001 Although the systems in use differ in the frequency with which the phone handset communicates with the base, they all share the same fundamental principle. The phone converts voice into impulses which are transmitted over radio waves at frequencies ranging from approximately 800 MHZ (eight hundred million cycles per second) to over 1,900 MHZ. Radio frequency (RF) radiation is one of several types of electromagnetic radiation. Electromagnetic radiation consists of waves of electric and magnetic energy moving together through space. These waves are generated by the movement of electrical charges. For example, the movement of charge in a transmitting radio antenna, i.e., creates electromagnetic waves that radiate away from the antenna and can be picked up by a receiving antenna.
