I first became aware of these new CT Scanners through a Popular Science Article.  Of course, they loved it!  But having spent a lot of time recently in CT Scanners for medical reasons, and knowing the radiation risks, I had some concerns.  So I contacted TSA:

Eventually TSA referred me to their website information regarding Computed Tomography (CT).   The information provided in the email response was less than useless.  And their email response only contained the information for the OLD X-ray scanners:

A recent Petapixel article provides the best source for relevant information regarding the CT Scanners and Your Film. Basically IT WILL DESTROY YOUR FILM!  So this is my Holiday Travel Warning.  You are permitted to ask for a hand search.  Do So!  Here is the current list of US airports with CT Scanners, with 300 expected by the end of 2020:

• Hartsfield-Jackson Atlanta International Airport (ATL)
• Baltimore-Washington International Airport (BWI)
• Chicago O’Hare International Airport (ORD)
• Cincinnati/Northern Kentucky International Airport (CVG)
• Detroit Metropolitan Wayne County Airport (DTW)
• Houston Hobby Airport (HOU)
• Indianapolis International Airport (IND)
• John F. Kennedy International Airport (JFK)
• Logan International Airport (BOS)
• Los Angeles International Airport (LAX)
• Miami International Airport (MIA)
• Oakland International Airport (OAK)
• Phoenix Sky Harbor International Airport (PHX)
• Ronald Reagan Washington National Airport (DCA)
• St. Louis Lambert International Airport (STL)
• Tampa International Airport (TPA)
• Washington-Dulles International Airport (IAD)

In addition to the safety of Our Film.  I am also concerned about the calibration of the machines, regular maintenance and the safety of the TSA operators.  What do they know and what are they being told about the radiation risks?  Lets give that some thought too!
