Biggest-ever mobile-phone safety study launched
The biggest study of mobile phones and health ever undertaken has been launched.
A least 250,000 people will be monitored for 20 to 30 years.
Experts hope the multi-million euro investigation will help settle once and for all the on-going debate about the safety of mobiles.
Up to 100.000 people are expected to participate in the UK, with others from Finland, the Netherlands, Sweden and Denmark.
