It is RF radiation not from some radioactive element.
An antenna when transmitting creates a voltage and a current. If the antenna is resonant the current and voltage though very slight work to create an efficient signal. At resonance they meet with as strong a force as they can create approximately 1 wavelength away from the antenna. At the frequencies we are talking about that is 1 or 2 inches, its a field that oscillates.
Now a full power radio transmitter or a radar antenna has a lot of power possibly 20 amps and 7,000 volts so there is a strong field created. High power electric lines also create a strong field but these are not antennas so there is no established resonant frequency as it is a long line, 60 hz isn't really the resonance of the wire but of the alternating current.These devices are a ways up in the air or far away from people generally. Your cell phone has a very low amount of power comparatively but as you hold it up to your ear, the resonant point could be just inside your head. If you use it a lot then there is a distinct possibility that there could be microwave created damage to tissue.
Could, because it really is not determined. Motorola and the other manufacturers created the phones with antennas that tilted away from your head, remember those? That was to move that resonant area away from your cranium. Personally I have not seen current information regarding the phones we use these days. Antennas are on the back of the phone and may have been designed to radiate away from the head.
Also I might add, a Bluetooth device on your ear though very low powered is also a transmitter and some folks wear them all day... I use a wired ear phone thingy because I find Bluetooth eats the battery to quickly.
As usual I have no ego in this discussion so if anyone has any corrections, feel free.
