Mobile Phones

 * __How do mobile phones use electromagnetic radiation?__**

When you speak into a cellphone, a little microphone converts the up-and-down signals of your voice into parallel up-and-down electrical signals. A chip inside the phone then changes these signals into strings of numbers.The numbers are then packed into a radio wave and beamed out through the phones antenna. The wave travels through the air at the speed of light until it reaches a nearby phone mast. The mast gets the signals and releases them onto an exchange building, where they are passed on to the target phone. On the same network calls made from phones have waves that travel straight to the mast closest to the target cellphone. In conclusion they use radio waves which are part of the electromagnetic spectrum which causes radiation like all other waves.

__**How does the radiation from mobile phones affect human health?**__

Due to their different effects on human beings and nature, electromagnetic radiation is known in two different forms: non-ionizing waves and ionizing waves. Radio waves, Microwaves, Infrared waves, and visible light waves are non-ionizing waves because they don't have enough energy to break atoms and molecules apart and turn them into ions, which are electrically charged particles. Non-ionizing waves do not damage tissues, cells, or genetic material (DNA) in your body meaning they cannot cause cancer nor any other illnesses.

X-Rays, and gamma rays on the other hand are ionizing waves, which at high doses, can increase your risk of cancer, birth defections, and genetical defects through the transformation of your DNA, resulting from the ionization of your genetic material and your cells.

This all means that the electromagnetic radiation from a cellphone does not harm or cause any distress to the human body in anyway. The only waves that can penetrate atoms and cause trouble in your system are X-rays and Gamma rays. Phone waves are non-ionizing. The electromagnetic radiation can cause a little stirup in you system but does not affect your body in any harmful or destructive procedures
