Mobile phone hazards

Mobile phones and wireless networks emit radiation in the microwave frequency range. Just as microwave radiation cooks food at high levels, it causes damage to human tissue and DNA at low levels. Hundreds of independent scientific studies have clearly shown that exposure to microwave radiation can cause severe and long-lasting damage; however, it might take years for the damage to produce noticeable symptoms in some people.
So what can one do to prevent or reduce the risks
and Try reduce mobile phone usage, wireless network or live near a cell phone tower.
and If you must use a mobile phone use it only in places with a strong signal. This allows the phone to transmit at low power (up to 100 times lower than its maximum value), reducing exposure accordingly.
and Minimize the length of calls.
and If you know where the nearest cell phone tower is don’t put yourself between it and your phone, otherwise the signal travels straight through your head.
and In your car use a hands-free kit with an external antenna and keep the phone away from your body. The external antenna should be as far away from you as possible.
and Do not use an earphone if it is made of conductive wire. Studies have shown that a metal earphone wire can act as an antenna and direct radiation into the head from the ear canal. Some earphones now use fiber optic cable or a hollow tube to convey sound.
