Merry Christmas to everyone!

I have to fly to Kansas City on Monday. I'm taking a D70 and a digital video camera. My question... do I need to do anything because of the x-ray machine? I know if won't "fog" the pictures, but I am unsure if there would be any problem with the CCD, electronices, etc.

I don't think there will be a problem, but if anyone would know, it would be someone in this forum.

Thanks in advance, and happy new year!

I haven't heard anything regarding problems with CDD/CMOS sensors... I do know that there was recently a test on digital media and the results showed that xray machines posed no problem.

No problem with the equipment -- but they will make you take the video camera out of the case and run it through separately. It's one of those terrorist tips. They found a piece of paper in a raid somewhere that says you can turn a video camera into a laser beam and destroy the planet so they now have ALL video equipment out of the case and x-rayed. If you don't pack to have it easy to remove the camera, then it can be a hassle. Pack your cables in a separate compartment or bag. Have the camera ready to pull out and plunk on the x-ray belt.

What about magnets?

Do large metal detectors use magnets? And how about large electric motors, or televisions? Wouldn't such magnetic fields cause problems for CF cards?

Compact Flash or any memory card does not use any form of magnetic bits. Info in CF cards is stored as electrons and
their ELECTRIC field, not magnetic. Hard drives, floppies, etc. are magnetic. These cards are completely impervious to magnetic fields.

JT has it correctly. Here's a link to a site that explains it all in more detail than you probably want -- but it's a fun site just the same. [img]/ubbthreads/images/graemlins/grin.gif[/img]

As the former head of engineering and now a senior advisor to the engineering departments for a very large multinational company , I can generally assure you that the x-ray machines used for carry-on luggage will not affect your CF cards or your digital camera sensor. Also turn your camera off.

Electromagnetic (electro and magnetic are different forms of the same thing - too many physics classes to explain - trust me on this) fields/radiation though will affect your camera sensor and CF cards - the issue is the intensity or strength of the field/radiation AND the duration of exposure.

Generally, if you pass security 'normlly' - put stuff on conveyor, stuff goes through x-ray machine normally, stuff comes out, you pick up stuff and go to gate - then you will be OK.

I would keep the wand thingy (very technical term) away from the CF cards though.

I am uncertain about the checked luggage x-ray machines and their affect on digital camera sensors or CF cards. These have focus intensifiers that will expose your camera to very high bursts of x-ray radiation (which too is another form of elctromagnetic radiation - another long physics lesson). I have seen several debates on their affect.

I can tell you this though, all packages recieved in all of our facilities are irradiated with very similar machines used by the TSA's checked baggage screeners and by the USPS. I know the scientists are insistent that their digital equipment and all electromagnetic type memory cards are delivered hand checked. Next year, the engineering department will do a thorough study on the matter. Notice I didn't say they were correct but who's going to argue with some who are nobel prize nominees?

JT & Dave, I was always wondering about that.
