- Except that the collision of x-rays with atoms may dislodge electrons, which
- *are* electrically charged. (It's been a LONG time since I was an EE major,
- so I looked this up in Encyclopaedia Britannica.)
-
- However, I'm of the unverified opinion that damage is more likely to be
- caused by the magnetic fields of the conveyor or other equipment in the
- airport scanners.
-
- In any event, ask yourself this: Is this data worth protecting? If so,
- then you should take whatever steps the airports will allow you in protecting
- potentially eraseable magnetic media. (When I flew through Atlanta recently,
- I had them hand-check my notebook computer and they asked me to remove any
- diskettes before they would put the carrying case through the x-ray machine.
- Incidentally, it seemed like 20% of the passengers were carrying a portable
- computer.)
