 * How does mobile phone effect humans with their levels of electromagnetic radiation?**

I think the mobile phones are a risk to humans because research shows that exposure to radio waves for long duration can only heat up the body tissues. EMF is the cause for human sickness and also known as electro magnetic waves.Mobile phones affect the body because the brain uses more energy. researchers don't know if it is good to use energy from the brain or not. When talking on the phone a lot your brain gets heated up. Some people also gets headaches after talking too long on the phone. MIllions of people use mobile phones but more research needs to be done with respect to health. This is my opinion but people might think that mobile phones are not a risk to humans.


 * How do mobile phones use electromagnetic waves?**

When you speak into your phone, a small microphone in the handset changes the up-and-down sounds of your voice into a joined up-and-down pattern of electrical signals. A microchip inside the phone turns these signals into strings of numbers. The numbers are packed up into a radio wave and beamed out from the phone’s antenna.
