From the TSA twitter account, I found this propaganda from CBS showing how benign TSA scanners are to our health. As I've said before, this is a secondary issue, but CBS's reporting here is abhorrent. I also found similar news stories titled "Body Scanners Don't Pose Health Risk." The doctor in the video should have his medical license revoked (if he is a medical doctor). There's just no medical data on this, and, I believe that most doctors feel that unnecessary radiation exposure is never warranted.
(I must say that I like the title of this report from an Australian news source: Full-body airport scanners 'as likely to kill you as terrorist bombs')
