Q about dose: Airport X-ray Security Scanner

["Robert Gunter" <rjgunter@icnpharm.com>]

Quick question,

If these things are effective  giving doses of 3 uR, why are the doses for
diagnostic X-rays so much higher.  I the beam intensity required for good
imaging of tissue and etc reallyt that much higher??  It seems like we are
talking orders of magnitude difference.

 was reported as 3 uR (0.03 uGy) for 4 views total (front, back, and both
 sides). >>
