In the United Kingdom alone around 16 million people regularly use mobiles.
The Government-backed National Radiological Protection Board maintains mobile phone radiation levels are well within safety limits.
But other studies have already shown links between the phones and long-term memory loss, high blood pressure and premature ageing.
The phones have also been linked to cancer, leukaemia, multiple sclerosis and Alzeimers disease.
The Government is set to announce further funds for research into possible health affects of mobiles early next year.
