Kelly,(posted 8567 days ago)I would look to other causes than the Xray machine. The problem is with the carry on machines, if they are putting out enough Xrays to harm slower speed films, they are harming the workers. And they do have to be tested on a regular basis to protect the workers. The things just aren't shielded enough for that high an output.
In the US you have the RIGHT to have film and cameras hand inspected. But of course, you have to have enough time to argue. If you have the time, ask for the supervisor.
