Apparently we get about 0.05 mSv per seven-hour flight (a chest x-ray is 0.04mSv). What does this mean for our film? Perhaps we shouldn't be as worried about the carry-on X-ray machines as much as background cosmic radiation. High-energy radiation can also flip bits in flash memory cards, so you digital photographers aren't as safe as you think you are.
