Regarding laptops and film at the x-ray counter. I agree that you'll
most likely find that you need only turn on the computer and show that
something is on the screen. For film, all should realize that x-rays on
film are cumulative, as they are on us. Even slow film, if exposed too
often, especially if it happens to pass through the machine at the same
angle, can be ruined. Also, many x-ray machines in out-of-the-way
places are much too strong. If the photos really matter, a
double-strength lead-foil bag is cheap insurance.
