The typical X-ray dose from the doc's office is equivalent to less than three hours of exposure to background radiation. That's background, everywhere in the universe type radiation. So, if you have existed in this universe for more than three hours, you've handled more than you got from the doc. Actually, if you've flown from New York to Chicago, you've gotten about the same hit as the X-ray machine (high altitudes are, obviously, shielded by less atmosphere). None of this is taking into account that gigantic fusion bomb in the sky. That thing zaps you with even more radiation.
So, assuming your piece collected and is re-emmitting all the radiation (which it isn't, but you know that), you will likely develop cancer about the time I win my eighteenth lottery jackpot.
