 * Radiation of cellphones heats brain tissue but the heating can only damage tissue slightly, but that damage is so (only the part close to the phone)
 * Some people get headaches over long periods of time
 * hypersensitive people can feel sick
 * Radio-, Micro-, Infrared-, and visible light waves are non ionizing which means they don't have enough energy to break atoms and molecules and convert them into ions (Atoms in which the number of electrons is not the same as the number of protons), therefor using a cellphone can not harm your DNA. unlike gamma or x-rays.
 * The radiation of cell phones can't cause cancer or other illnesses unlike gamma and x-rays.
 * There is no absolutely safe level of radiation, even cell phones can damage your tissue, but the effect is hardly [[image:http://images.intomobile.com/wp-content/uploads/2008/08/samsung-phone-radiation.jpg width="168" height="228" align="right"]][[image:images_(2).jpg width="249" height="201" align="right"]]noticeable.
 * the National Institutes of Health in the US reported higher sugar use in the brain (a sign of more activity) after 50 minutes on a phone
 * glucose use increased by 7 percent in parts near the antenna
 * Many scientists argue about the effects of cell phone radiation, but none say there are any severe risks.
 * 90 percent of scientists say cell phone radiation is nothing to worry about

=Health affects of the cell phone=

Here I will tell you some information about the health effects of the radiation of cell phones. There are many different opinions on how badly the radiation affects you but most people (I am one of them) do not think there are any severe things that can happen. I think that because we use them everyday and on average the average age is still rising. There are some people who are hypersensitive and they can have bad symptoms and the brain temperature does slightly increase, but nobody dies of cell phone radiation. There are also no people who have gotten sick from cell phone radiation, however it is probably a good idea to limit the time you talk on phones.

=How do cell phones use electromagnetic radiation=

When you talk on a cell phone, a transmitter takes the sound of your voice and changes it into a continues sine wave. A sine wave is just a type of continuously varying wave that radiates out from the antenna and fluctuates evenly through space. Once the changed sound has been put on the sine wave, the transmitter brings the signal to the antenna, which then sends the signal out.
