My approach: 1. First ask if possible to inspect rather
than scan; if not, 2. Request  security to feed film through
separately, isolated from all other baggage (surrounding density) which
might necessitate an increase in dosimetry - - AND, lay the film such
that the beam passes perpendicular  (NOT parallel) to the long axis of
the film  cartridge.   (I pre-pack in this geometry using a thin flat
plastic food storage container with a pop off lid.)  X-ray absorption
is logarithmic.  Cut the thickness ~ in half (width rather than height
orientation) and you decrease exposure by a log function.

Almost the same approach as me, for exactly the same reason. The main difference is that I pack the film canisters in a resealable plastic bag so that the inspector can easily see that it is film as I think this increases the chance of a visual inspection.
