   A while ago I made the comment in this newsgroup that I thought that disk
drives were safe from soft X-rays because of their RF shielding, which is
required by the FCC.  And yes, I do know that X-rays and radio are not the
same... :-)
   However, you ask about floppies and tapes.  Magnetic media which are
passed through an x-ray machine are definitely at risk.  The reason I made
the comment about hard disks is that they are shielded quite well.
   Unshielded magnetic media definitely should not be passed through the
x-ray detector.  Although I haven't heard of any problems, the chances for
difficulty are at least 100 times greater than with fixed disks.
