//For the average person how do __**cell phones**__// __**//use electromagnetic radiation?//**__

__**Cell Phones**__ use __**Electric and Magnetic fields (RF-EMFs)**__, known as __**Electromagnetic Waves**__, to create a wireless link to communicate between mobile phones. Generally, when someone talks through the phone it starts giving off electromagnetic waves. The other person listening through the other phone then hears the talker's voice because of the phone's antenae capturing the electromagnetic waves. The type of electromagnetic wave a cell phone uses to communicate with other phones are __**Radio**__ __**Waves.**__ Mobile phones use electromagnetic radiation because they emit radio waves. There are many other types of electromagnetic waves. __** The Electromagnetic Spectrum **__ (Shown below. is a chart displaying all of the electromagnetic waves in order                 from long **__Wavelengths__** and low __**Frequencies**__ to short wavelengths and high frequencies.

Forms of ionizing radiation are waves such as **__X-ray Waves__** and **__Gamma Ray Waves__**. These types of waves in high doses, can increase someone's chance of birth defects and genetic defects and can even increase the risk  of Cancer because of DNA mutations from molecule and atom ionization. Ionizing radiation is no form of radiation you can call completely safe. **__I__****__nfrared Waves__**, **__Visible Light Waves__**, __**Microwaves**__, and **__Radio Waves__** are examples of non-ionizing radiation that do not contain enough energy to split apart molecules and atoms and turn them into __**Ions**__. Ions are electrically- charged particles. This results to non-ionizing radiation unable to damage DNA and cause Cancer or any other fatal human illnesses. As I recently just mentioned, radio waves are forms of non-ionizing radiation. This proves that the waves that come from a cell phone are not harmful to mobile phone users around the world.
