THERE IS NO DANGER FROM MOBILE-PHONES' RADIATION. It is a non-ionizing one.
Besides, had there been an actual threat of brain-cancer from using them, given the fact that they've been around for about a quarter of century(!!) by now, we should necessarily have witnessed a GIANT amount, of brain-tumors, at the level of OVER A BILLION CASES – with HUNDREDS OF MILLIONS DEATHS.
NOTHING LIKE THAT HAPPENED.
So, unless you are a semi-retarded, mad-eyed nibiru-worshiping hippie from some psychotic "back-to-mother-nature" cult or another, you can see, at once, that THERE IS NO DANGER THERE, PERIOD.
That "Dr devra davis" person should be thrown away in disgrace, NOT lecturing people – and the very fact she not only gave that lecture, but it was published on youtube, should tell us EVERYTHING we do truly need to know, about the level of aussie "science" and "scientific community".
