     "A dental x-ray is equal to a day in the sun" has turned out to be a 
     remarkably accurate projection--even if for all the wrong reasons.
     
     The effective dose from a single intraoral film, done with 
     state-of-the-art technology in 1997, is approximately equal to one 
     day's natural background--using the NCRP estimate of 3 mSv/y.
