I doubt that any airport anywhere uses neutron scanners (whatever those may be).

You're right of course, I'm not sure what I was thinking when I typed that.

I of course mean the (typically backscatter x-ray) full body scanners.

For what it's worth, even though I cited the wrong tech (see my other reply), gamma ray ("neutron") scanners are pretty cool tech, and worth knowing about :)
