There is nothing wrong persay about sending breast milk through an x-ray machine. But since breast milk is considered a medical liquid, women have the right to request a hand check, rather than sending it though. Often times if you send that much liquid through the machine they flag it and hand check all your carry on luggage, it's just easier to show them upfront.
So WHY did she have an issue with the milk being x-rayed?
I wouldn't want them sending my breastmilk through the x-ray either. There is no way to know if the radiation has any effect on the milk itself. I wouldn't want to feed that to my child not knowing if it could be harmful. I won't even fly at this point because the government is out of control with all of these new regulations. Isn't it supposed to be a government by the people? It seems to me that they're just inching their way into complete control. It does need to be stopped.
