Radiation from airport scanners very low: study

• Reuters
Airport scanners are an "extremely low" source of radiation exposure that poses virtually no health risk, not even to frequent air travelers, U.S. researchers said on Monday....
"There is such a vast difference between super-low doses of radiation and the really high doses that happen if you are in the middle of a nuclear accident," said Dr. Rebecca Smith-Bindman, a radiology professor at the University of California, San Francisco, whose study appears in the Archives of Internal Medicine.

My problem with this study--which I have not seen--based upon this news story is whole body  dosage was used.  The vast majority of radiation doesn't penetrate more than half an inch into the flesh so a great deal less than "whole body" is being exposed.  If I were a frequent flier/air crew (who already get double the dosage of radiation at high altitude per year as "normal" people) or even more a TSA agent standing around the x-ray machines all day I would not like the frequent exposure.  Radiation damage is cumulative.  There is no such thing as a safe dosage.  Just acceptable tradeoffs.
