I've never had a problem with X rays in airoprts and wouldn't be concerned over this. However bearing in mind the rough handling the bags get on planes I would be concerned about that and would keep the camera in your hand luggage because of this.
I do a great deal of flying and take my digital cameras wherever I go. There are no problems with airport security equipment, but I would never even consider placing my equipment in the hold. Always carry it as hand luggage. It is also quite safe to send it through the scanners.
As per previous postings, never leave anything of value in luggage that goes in the hold and confirmation that security checks/scanners at the majority of airports throughout the world will not harm digital or film media.
I've been through many, many times with both types and it's been fine - in fact many airports display the information that it is safe to do so.
No doubt the FE, a seasoned traveller who visits many parts of the world, will also reassure you.
Both my employees and myself travel a lot doing location shoots all over the world. We take large amounts of photographic equipment with us - both conventional film and digital. All cameras regularly go through airport security scanners without problems. However, we do, wherever possible, buy film in the country where it is going to be used and have it processed there. This has three advantages:- very often film is cheaper abroad, it avoids any possiblility of fogging at airports and it avoids carrying unexposed film rolls and canisterss ripe for any over zealous (nosy) security officials to open, and consequently, ruin.
My partner is an airline pilot who regularly carries a laptop, digital camera and a film camera when working. He's never had any problems with security equipment damaging equiment.
