With the increasing popularity of mobile phones around the world, it
is no wonder that people have started questioning the safety of these
devices.
Mobile phones are two-way radios that transmit and receive information
via radio waves, also known as radio frequency (RF) energy. Whenever the
user makes a phone call, his voice is encoded into radio waves and transmitted
through the antenna to a nearby base station. These radio waves are at
the heart of the controversy over cell phone safety.
Radio waves are just one of the many forms of electromagnetic energy
that form the electromagnetic spectrum. Other types, including gamma rays,
x-rays and light, also belong to this spectrum. They differ from radio
waves in terms of wavelength and frequency.
There's concern that this may pose health risks. This question is being
addressed by ongoing scientific studies. While most scientists agree that
there's no proof of greater risk, it makes sense to minimize your exposure.
If you want to be on the safe side, the easiest way to minimize the
radiation you are exposed to is to position the antenna as far from your
head as possible. Utilizing a hands-free kit, a car-kit antenna or a cell
phone whose antenna is even a couple of inches farther from the head can
do this most effectively.
Another way is using a radation shield. Attaches in seconds and fits
under removable cell phone fascias. One size fits all mobiles.
