British researchers have begun the largest study in the world to find whether mobile phones and other wireless gadgets might damage children's brain development, the Newsmax Health reported.

The Study of Cognition, Adolescents and Mobile Phones, or SCAMP, project will focus on cognitive functions such as memory and attention, which continue to develop into adolescence - just the age when teenagers start to own and use personal phones.

While there is no convincing evidence that radio waves from mobile phones affect health, to date most scientific research has focused on adults and the potential risk of brain cancers.

Paul Elliott, director of the Centre for Environment and Health at Imperial College London and the study's principal investigator, Mireille Toledano, aim to recruit around 2,500 11 to 12 year-old school children and follow their cognitive development over two years while collecting data on how often, for what, and for how long they use mobile or smart phones and other wireless devices.

Parents and pupils who agree to take part in the study will answer questions about the children's use of mobile devices and wireless technologies, well-being and lifestyle. Pupils will also undertake computerised tests of the cognitive abilities.
