Flying with EX1 and Airport X-ray
 
When we have had cameras in the past with CCD blocks, we have had problems with dead pixels after flying with them (going through airport X-ray I assume). I was wondering if there would be a difference when flying with the EX1, since they are CMOS chips? It would seem that there isn't as many problems with CMOS vs. CCD, but I could be wrong. People fly with still cameras all the time and I don't hear about dead pixels in them too often. Any thoughts on this?

Thanks
Kit

We did a heck of a lot of traveling to and in China with my HC7 and it went through tons of film safe X-rays and I don't see any dead pixels.

My 2 cents: Have never heard about xray blinding sensors.
chemical film yes, but video sensors: NO.

Airport xray machines will not harm the sensors. High energy cosmic and solar particles are another matter. On polar routes there are higher risks and the higher the altitude the higher the risk. From what I've read the energy levels are so high as to make shielding impractical. The probability of this happening does seem to be very low but can be quite damaging if you get hit by a big storm of particles.
There's a wealth of information about this from the people designing spacecraft. At 40,000 feet there's not much between you and the rest of the universe, more so at the earth's poles. However unlike a spacecraft you're not there for very long and the particle storms are rare. When travelling with a camera I can think of more pressing things to worry about, like baggage handlers. They seem to be fairly predictable in doing damage or simply making your gear vanish and even more difficult to protect against.

I have had CCD's in a couple of my full size broadcast cameras damaged by cosmic rays on trans-atlantic flights. Before the flight no dead pixels, after the flight 4 or 5 dead pixels. I don't know if CMOS sensors are affected in the same way, but so far my HC1 which has been on the same flights as my other cameras has remained intact, but then so also has my Z1 which is CCD.
