From what I understand she was past the TSA checkpoint. But whatever.
She could have gotten past the checkpoint by having the thing in here pocket. The walk through is not an x-ray. It is a metal detector. They can’t use an x-ray on people due to federal restrictions.
An example is when I was working for Uncle Sugar, I had to keep track of my roentgens because I worked in a radiation atmosphere a lot. I had to make sure I didn’t approach 200 rads which would mean death. So x-rays were limited for me and many like me. They use a new detecting system today. We were dinosaurs.
