I thought they just said on the news that cell phone radiation isnt that bad if you use a hands free piece and dont use the tommyboy sweatband idea to hold it to your head all the time.
Having done recent research on radiation dosing you most likely got more radiation from you flight from Europe to the States than you will in years with your cell phone, unless of course you are glued to it 24/7.
I am also curious how something can protect from radiation dosing that is not in a direct line between the emitting device and the person.
Good luck with it.
