Hey all, Im going to Korea tomorrow,

and I've been wondering about Airport securities (X-Ray scanning, etc) and digital Cameras, USB Flash drives, and MP3 players.
Question #1: Will any of the electronic items I stated above be compromised upon entering the dreaded X-Ray machines?
Question #2: Are there any special measures (ie. Not being able to have the electronics with me) on handling electronics?
Question #3: Am I really...like..REALLY not supposed to say "bomb" on an airplane?
