A man who admits that mobile phone usage may have caused a tumour in one of his ears is helping to introduce wifi networks emitting the same kind of radiation to hospitals and colleges.
Eight years ago Peter Lyons was left without the use of half of his face after an operation to remove an acoustic neuroma in his phone-using ear.
Now he is network development manager for the Open Learning Partnership, a charity that provides people with access to the internet.
Recent research has linked acoustic neuromas with mobile phone usage. Lyons said that, despite his concerns about being overexposed to electromagnetic radiation, the use of the wireless networks, or wifi, is justified because they are not operated close to the body like mobiles.
