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.
