How do cell phones use electromagnetic radiation?
A cellphone is usually all a kid wants. They want to call, text, surf the net, and IM. All the kid thinks about is what they want to do on the phone, but they never stopped to think about how the cellular phone works in the first place! Cell phones use high frequency microwaves to transmit signals. It travels fast, but has a low amplitude. When you call someone from a phone, it sends out microwaves. The microwaves go to a satellite. The signals then travel to the receiver on the phone. After that the call has been placed.


 * How Do Mobile Phones Effect Humans With Their Level Of Electromagnetic Radiation?**

Cellular phones are meant to be cool, and useful. Usually when one is about to purchase a cell phone, health implications are usually last to be thought of, if not not considered at all. Research shows, that there is not definite health implication when using mobile phones. The National Institute of Health reports that there is some effect on the brain. Some evidence is that they found that brain activity is increased in the use of cellphones for a duration of 50 minutes or longer. Whereas professionals in the United Kingdom report no health risk what-so-ever. In Denmark, an experiment was conducted with a cell phone user, confirming no connection between using cell phones, and cancer. Some of that increased activity is high sugar use in the brain. Researchers state that there is more glucose use in the brain, and was increased by 7%. It is yet to be confirmed whether that is bad or not, therefore, more research must be done on this subject.
