<p>Last time I flew with film in my carry-on camera bag. The scanners for carry-on are supposed to be less powerful than for the ones being used on regular baggage.<br>
I had no problem with either the B&W film (TriX) or the color negative film I used at that time.<br>
No fogging at all that I could see.<br>
I hope you enjoy Ireland. <br />You'll see more shades of green than you thought existed. <br />Great scenery, great photo-ops; and great people.<br>
The food & brew aren't too shabby either! :D<br>
Cheers!</p>
