philip2004uk, Why the constant pre-occupation with mobile phone radiation? The telephone frequencies are around those used by sixties primary radar and, consequently, around those used for jamming same. Jamming - as in very heavy, glycol cooled equipment at the back end of Vulcans. Believe me, if mobile phone 'radio waves' had any effect on you then there'd be no one left around from the V force. Certainly not ECM fairies.
