KM-25,
I've been following this thread. I understand your concerns and, mine would be similar in planning a project.
In many years of air travel with film, I never had any film damage from X-ray machines. I did have some "incidents" with TSA people. Some friends had issues with film damage when traveling. CT is a game changer.
I decided years back if traveling out of the country or, for any in-country travel where I thought my Exposed film might be compromised that, I would process it on site before traveling to another site. This of course means a developing kit with a water filter, etc.
My thinking was driven by, the personal value I placed on my time and work, vs the risk of loosing it all through one mistake by a luggage inspector with his hands on the intensity control of an airport scanner. Shielded Film Bags are a joke. The inspector just cranks up the X-Ray level allowing a view of the bag's contents.
Anyway, I bought one of these a while back. Not the home darkroom but, better than a changing bag.

I hope you find a workable solution to the problems we film people now have.
Also, I'll add, in working with one of the big three camera makers, and this was back in the CCD Sensor days, there were reports of sensor damage by airport X-Ray machines. I don't know that these stories made the photo press but, they were well known within the company's design group and the pro user program.
Good luck to you, pkr
