“We thought this film was defective. But we were mistaken. This is how radiation looks.”

This is what radiation looks like.

 

As I traveled internationally in business I carried one of those single-use film cameras (1990’s).

Each time I went through a security check they insisted on X-Raying the camera. When I finally got the film developed it was fogged so badly that nothing on the film was recognizable.

…and that’s why people using X-Ray equipment wore film badges.
