X-rays themselves won't damage magnetic media. Watch for close 
magnetic fields (e.g, don't put them in a bag on the floor of an 
electric train with motors possibly under the floor).

Magnetotstatic fields fall off very rapidly with distance, so a few 
centimeters of separation from the field make a difference.

As the X-ray machines may generate magnetic fieldes, I'd put the 
discs in the MIDDLE of a bag and let them go through.

You could always back up the presentation on a writeable CD. In fact, 
it's got to be better than 250 floppies.

Or a cheap, old parallel port tape backup with 250MB capacity.

Best wishes,
