Where’s the evidence of a threat to our health from mobile phones?

DR ELIZABETH CULLEN of the Irish Doctors’ Environmental Association (Irish Examiner letters, March 18) claims there is “ample scientific evidence” to demonstrate that signals from mobile phone masts affect physiological processes, with the strong hint that these effects are negative to our health.

I went to the association's website to look for this ample evidence because I'd looked for it several times before and had not been able to find any.

Unfortunately, I couldn't find even a single reference to any scientific evidence about the health effects of mobile phone systems on their website.
