=**What is electromagnetic radiation?** = ====A part of all of our daily activities is watching TV, listening to the radio and using our cellphones. All these use electromagnetic waves. Radio waves, microwaves, visible light, and x-rays are examples of electromagnetic waves, electromagnetic waves are made by the movement of electrically charged particles. These waves in other words are called "electromagnetic radiation waves" They travel through empty space at the speed of light. All these devices use radiation and may be a health hazard. ==== =How Do Cell Phones Use Electromagnetic Radiation = ==== Cell phones use wireless connections by using electromagnetic radiation waves to send and receive messages instead of them traveling down a wirer cable. When you speak into a cell phone, a sm all microphone in the hand set passes the up-and-down sounds of your voice into a ascending up-and-down chip inside the phone that turns the signals into numbers. These numbers are gathered up into a radio wave that emits light from the phones antenna. the radio waves races through the air at the speed of light until it reaches the nearest cellphone hub.==== =**Electromagnetic radiation and possible health hazards** = ====I believe that electromagnetic phone radiation could possibly grow into a bigger health hazard, more than it is now. Non- ionize radiation waves like radio waves, microwaves, infard rays and visible light waves don't have enough energy to break molecules and turn them into ions. X-rays and Gamma rays are a form of ionize radiation, if the rays are at a very high doses the risk of one getting cancer increase. I believe that this means that excess time on the phone might give you cancer or extensive brain damage and other bodily functions, for example the heart and the brain. ====

= Do mobile phone radiations affect the body? = ====Thousands of people use mobile phones and mobile phones use electromagnetic radiation waves for communication. Research shows that exposure to electromagnetic waves will only heat up the body tissues I believe that more time on the phone after this has occurred may lead to a health issue. The latest research implicates that over ninety minutes of mobile phone use will increase the amount of sugar (glucose) in the body by 7%. This is an open debate with all scientists around the world but I strongly support that cellphone use may lead into heart failure, brain damage etc. ==== = Health Hazard Or Not = ====Research suggest that brain activity is affected but cannot prove that it may be a health hazard. Mobile phones were attached to both ears of each participant of an experiment to prove this. One phone was off but the other was muted, so the person could not be able to tell the difference.Their brains were scanned to pinpoint any change in sugar use, which grew in parts of the brain close to the antenna. I infer that excess sugar in your brain might not be good for you, but large amounts of research needs to be done on this theory. The possible effects of mobile phone radiation is skin burns, deep burns, heat exhaustion and heat stroke. Headaches are also one of the possible effects, hypersensitive people begin feel sick after over fifty to ninety minutes being on the phone. These possibilities haven't been confirmed yet. ==== =Sources= Mobile Phones 'affect the brain'." //BBC News Health// . BBC, 23 February 2011 . Web. 5 Apr 2011. .
