2) X-rays. I took a trip about 12 years ago where I went through about 15 x-ray machines. It even got scanned in New Dehli *leaving* the airport. I noticed no fogging at all. I don't know if they have increased the dose x-ray scanners give since then. I would actually expect it to have gone down (except for homeland security).
