What is it about?
Mobile phones use electromagnetic fields to establish a wireless communication link to the nearest base station. When someone speaks on a mobile phone, that phone is sending out electromagnetic waves (EM). When someone listens on a mobile phone, that phone is capturing electromagnetic waves. Electromagnetic waves go out and come into a mobile phone through its antenna. That antenna is located very close to the user's head, and people have naturally wondered about the health effects of radiation from mobile phones since their inception.

Why is it important?
Electromagnetic radiation is every-where. More and more wireless communication devices (mobile phones, pagers, wireless network systems, and so forth) are expected to increase in the future, as is the artificial electromagnetic radiation from such wireless devices. How to minimize your exposure?
Perspectives
The radiation from mobile phones deposits very little energy in the human head, and therefore the rise in temperature is only a fraction of a degree.
