Vibration from the aircraft causes more equipment malfunctions than the X-Ray machine does.Definitely, plus, as mentioned, the baggage smashers.
If "baggage screening" X-Rays actually caused electronics damage you would
see far, far more of it. The screening machines use a level of X-ray
radiation several orders of magnitude
below medical diagnostic exposures.
We are exposed to more natural X-Ray radiation (from the sun & space) during a commercial
flight from Los Angeles to Denver than we are during a Chest X-Ray series (two views).
NO studies have ever shown that X-rays have any deleterious effects on
implanted medical devices: Pacemakers, Insulin pumps, Intrathecal pain pumps, etc.
In fact these devices such as pacemakers are installed using fluoroscopy
(think video x-ray images) during surgery, which uses much higher levels of
radiation than typical "still frame" diagnostic x-ray imaging.
So it's a pretty "out there" assumption that a an X-ray security screen
exposure would effect our commercial electronics, built and tested to far
less rigorous standards than implanted medical devices.
