Using a CATEEN scanner, Dr Michael Klieeisen and colleagues at the Spanish Neuro Diagnostic Research Institute in Marbella produced the first images showing:

• how radiowaves from mobile phones penetrate deep into the brain, not just around the ear

• that a mobile phone call lasting just two minutes can alter the natural electrical activity of a child's brain for up to fifty minutes

Previously it was thought that any interference of brain chemistry and brain waves stopped when the call stopped.

Michael is concerned that regular exposure to mobile phone radiation might damage children's immune systems.

Dr. Gerald Hyland, a UK Government adviser on mobiles, found the results "extremely disturbing". "It makes one wonder whether children, whose brains are still developing, should be using mobile phones," he stated. "(It) could lead to things like aggressive behaviour, lack of concentration and memory loss, affecting their learning ability in the classroom if they have been using a phone during break time, for instance."
