It looks like they pulled up a very old press release and plugged in the germane numbers without taking into account what has been learned in the interim. 20-30 years ago, a dental x-ray probably caused 1Rem of exposure.



Actually it didn't - 100 mrem is a pretty good EXPOSURE number (for each

and it WASN'T dental techniques that led to the extinction of the
