X-Ray damage or something else?

The attached negative scan shows a thin curved line running along the full length of a roll of 120 Tri-X. It was scanned by x-ray on my outward flight and to avoid the possibility of encountering a CT scanner on my return flight, I instead sent it home by DHL, who informed me they only x-ray packages and do not use CT scanners. I travelled with 20 rolls of the same film and only two of them have this line. Any thoughts?

It looks close enough to images you find on the Kodak page - although that line is very very fine. It's rather difficult to see anything else (other than damage from the factory somehow) causing it. And it does have the look that, if it were spooled up, that line would be a "slice" (at and angle) through the film.
 
One could determine the x-ray wavelength from this probably

Looks textbook irradiation to me.

But what they didn't state was with what dose. It may have been more than your film preferred to have seen.

Very true but how would only two rolls out of twenty be affected?
 
Stupid question but what about new film that you buy.....thats shipped out all over the world by Kodak....surely that undergoes scans etc, whats the deal with that? meaning thats already +1 scan (at least) on your new, unused film? Ive never had an issue, but its made me think, with film as I always buy from BH Photo in the USA. Yes Ive answered my own question in practicality but I want to know of fresh, unsold film that Kodak sends out suffers from X-rays going to distributors?
 
That question is asked often and the only logical response is that Kodak et al. make agreements with carriers that allow their shipments to pass through without being subjected to fierce xrays. This likely involves specific measures w.r.t. packaging, labeling and probably alternative inspection methods.

There was a recent issue with heavily irradiated Kodak color film distributed to or through a Chinese channel. They didn't use any precautions/arrangements and the film got blasted into oblivion, which they found out only when customers started to complain.

Shipping film is tricky business, especially with the increase in the use of xray and CT imaging for security purposes (esp. to detect illegal drugs & weapons transports).
 
very interesting Koraks thank you for this. Regardless of where in the world outside USA we are subject to this I guess. I assume Kodak ships to a main distributor in Europe and from there throughout the physical continent. My main worry is for motion picture film as I shoot 16mm and that has to go out from me via an airport normally with family/friend to take it for me to UK and in that case Cinelab London. That being said the hand luggage xray has not fogged any of my cans. As for photographic film no issues as I process my B/W and Colour negatives myself as we all do in here mostly.
 
Kodak Alaris distributes to local distributors, who in turn distribute to either retailers or even more local distributors.
Kodak Alaris and its customers cooperate with respect to these issues, but once the film is bought from Kodak Alaris .....
 
There are established programs in the United States, at least, to minimize risk to sensitive shipments. "Trusted Shippers" and "Certified Cargo" are two such processes.

For goods shipped as cargo on commerical aircraft, see page 2:

I'm not aware of what might be done for ground/sea shipment, but It wouldn't surpise me if there was an analogous process. And I certainly have no knowledge of the ROW programs, if any...
