"In 42 minutes of living you're exposed to more background radiation than from a general use X ray."
Don't you just love how they skirt the issue? Says nothing about the cumulative effect of that or any other type of radiation specific to these machines.
They more or less say without saying "you could walk through one of these scans every hour and be just fine". Well, if its danger level is so overblown, then why isn't everyone making fully developed photos of their innards with higher exposures to x-ray machines?
