I have a concern about RAI treatment. I was told that I will receive a letter stating what dose I had and that should get me through the detectors at the airport. I was told that I will set of the alarms for 90+ days. Thats a very long time. Anyone experience setting off alarms at the airport and how did you handle it. Aside from the embarresment of alarms going off, did security give you a difficult time. I will need to travel after my RAI, and worry about the airports, so any advice or experience would help.
