This is probably a dumb question, but I have to ask it anyway!
Do x reys affect developed E6 and K-14 film? I need to get my slides delivered to work for convenience and they employ an xray scanner to check parcels for security .
The cautions are te same as for black and white film. The carry on scanners used in the US and Canada are not a problem unless you put the film through them more than 6 or 7 time. Those used in other countries may have higher x-ray output, and your film may tolerate them less well. The scanners used for checked baggage are very powerful, however, and they may affect the film.
