                    We know that mobile phones emit radio frequency radiation from the handset and that these low-energy electro magnetic waves travel into the head .But do they cause injury to living tissue , possibly triggering a brain tumor or other disease ? There has not been much research into the effect of the radiation especially over the long term . The technology of mobile phones keep changing .

                        Should you throw your mobile phone out ? Not necessarily as the medical findings have to be repeated by other studies to be of much significance .

So if it is possible use a land liner , use text messages rather than voice and for voice calls on a mobile use headset . If you have children think twice about giving them a mobile phone although there is no direct evidence the phones harm children any more than adults . But some experts argue children’s developing brains are more susceptible to damage . Whatever is said mobile phones have become indispensable for our daily life. So they must be used but not unnecessarily  .
