Actually, it's not this one (radio active-) airport scanner that will destroy your film.
As light is cumulative (an X-ray exposure is adding 'light' too): multiple scans AND the initial exposure (made by you) all together, that does the damage.
The engineers are stating that their scanners are safe, which is correct as they test by simply passing the film just once, and then developing it.
But, suppose that your journey to Chicago begins in Frankfurt with a transfer in London, arrival in New-York where there is an other transfer to Chicago.
To how many scans will the film in your luggage be submitted? Then, at your arrival, the film is 'normally' exposed during you visit, after which you return to Frankfurt...
These films might be exposed 5 to 7 times!
Yes, the airport scanners are safe, but just for ONE (X-ray) exposure (perhaps two)...
