Mobile phones operate by using radio waves, a form of non-ionizing radiation. Since mobile phone signal stations could be in any direction from the person using the mobile phones (the devices are designed to transmit radio waves in all directions in order to catch this signal, including a proportion towards the user’s body), leakage of radio waves onto the phone shell can also occur.

The radio waves that are directed towards the user’s head can penetrate up to a few centimetres and be absorbed into body tissues. When the waves are absorbed, the energy is transmitted to the body tissues and the energy from these waves and the body’s own metabolism add up. The body can accommodate this extra energy up to a certain level. However, when this threshold is crossed the extra energy becomes translated into temperature rises and thermoregulatory responses can occur. Certain people in the population can, for various reasons, be more susceptible to these heating effects of radio waves and their consequences.
