Mobile phones have long been the subject of claims that they are a health hazard. While conclusive evidence has yet to be produced to prove this, I believe they are a danger when used frequently or for long periods of time. They emit radiation even when they are on standby.

What you can do:
Mobiles transmit at maximum power when you switch them on and off, when connecting and disconnecting a call, and while ringing, so hold the phone away from your body while dialling out, and don’t put it to your ear until the person you are calling has answered. Use a hands-free kit with air tubes whenever possible and keep calls short.
When texting, hold the phone away from your body when sending the message. Store a phone in your handbag or briefcase, not in a pocket and not in a baby’s pushchair. Don’t keep your phone on a bedside table at night, particularly if it is charging - because the charger unit gives off high levels of EMFs.
Avoid using music players built into mobiles at all costs. The signals produce microwaves while you are listening to music.
