I've just come back from my trip to Asia carrying quite a large amount (70 rolls) of 120 film. I have only encountered a single CT scanner which was the new "smart" lanes in Hong Kong HKIA. In the instruction signage there was a footprint mentioning that "if you carry photographic film approach the staff" and they proceed to do a hand check. Funnily on this time back, I had just had 40 rolls, half of them BW and exposed to develop at home. The agent mentioned "so many rolls"

Actually, even in my outward leg of the trip with the older scanners HKIA accepted Hand Check request.
I taped Kodak's "Do not Xray" labes to the ziplock bags and carried the press releases from Fuji and the other imaging consortium Ilford pointed me to; The latter was never shown.
As of the whole: For practical reasons I have let the film through a couple old Xrays. Stockholm Arlanda (terminal with old scanners) politely refused and provided a comforting diagram of the exposure level of the Xray machine, something which actually surprised me. However, the agent did handcheck Delta 3200.
Then arriving in the Philippines there was a large old scanner for customs. It was a bit hectic so I just let the film through. That many 120 rolls do appear interesting in the Xray and was guided to a secondary screening, one of the agents was concerned about having damaged the film as he saw the Kodak labels.
During island hopping there were about 3-6 additional Xrays for some of the film. I just carried a Domke lead bag and put it through. It was interesting, and often flagged a second look. Sometimes the agents didn't even get bothered.
It is also interesting to experience differences in security. I often just let the film cameras (Fuji 6x9 and a folder) go through in the bag, and one European airport in transit flagged my bag and the agent was not happy that I did not take them out; otherwise no problem in the rest of controls!
C41 I developed locally in HK and the lab scans show good results. There are color and shadow inconsistencies that I attribute surely to just minilab scan quality. Most of the film was expiring 2023 and frozen. I do need to sit and look into the Negatives and Slides.
I will develop the B&W soon, and mostly just interested to see if there are any ill effects in the Delta 3200. It has gone through 2 (non CT) scans.
