Reply #107: You fly often enough that you probably should opt out.

For the average person who only flies once or twice a year to visit their Aunt Mildred or whatever, it's not a concern. In addition if you had rad health training (as I have as well), then you'd know that the X-ray is simply a lower powered form of gamma ray and behaves in a similar fashion. In this particular case these machines could be shown to be similar to a low level beta skin exposure, which currently has a federal maximum limit of 50R and 15R for the eyes.
