That means don't put your memory card in your pocket and then walk through the scanner. This doesn't seem right. I have read MANY warnings about how to travel through airports with photo gear, and I have not heard of this before. [And for what it's worth, the risk to film at less than 400 ISO is pretty negligible if you only have to pass through a few X-rays.] I am willing to be educated, however. But I need to see the data about this from a reliable source. I guess the fact that I did my postgrad work in Missouri shows sometimes. So, Walter, do you have a reference? ciao rand
