a typical chest x-ray gives off 10mrem, background radiation from the sun, manmade objects, etc we get about 650mrem total per year per person in the US. you could safely double that with no adverse side affect. they say cancer increase risk by 10% for a total of 250,000mrem total. meaning you'd have to get somewhere in the neighborhood of 3,500-4,000mrem per year for 70-75 years.
are cell phones really putting off that much radiation? doubtful.
