If airport security scanners of any kind (xray, thermal, whatever else they use) looked at two items:
- A printed paper textbook
- The same printed paper textbook into which we have inserted a regular folded US letter-sized paper with something written on it with a pencil, pen, marker, etc.
Could the security be able to detect the difference between the two?
Best Answer
No, it would look exactly the same as far as the x-ray is concerned.
Think x-ray passing through paper and ink.
Thermal?
