We sometimes don't think about it too much, but you might want to think about the damage a mobile phone
can do to you when you place it right at your ear. When you get down to it and analyze the components, you have to remember that there's a battery being drained, antenna emitting signals, and other unseen forces that may have an adverse effect on your health. In a world where we are trying to be connected at all times, we sometimes forget we are using devices that emits some radiation – some more than others. If you look at the top of the list provided by the Environmental Working Group, some of them like the myTouch 3G and BlackBerry Curve 8330 are no brainers because of their focus on data use. Others like the Jax S1300 and Motorola VU204 are basic phones that people might not consider emitting tons of radiation. Samsung looks like they're making a conscious effort to provide low emitting devices based on what's on the list. Go check it out and see where your mobile phone stacks up. Maybe you might think twice about putting that phone to your ear the next time around?
