X-ray fluorescence from a film radiography intensifier screen

This video is a demonstration of x-ray fluorescence. An intensifier screen was removed from a surplus film cassette. When exposed to x-rays this screen fluoresces (glows) green. For x-ray film, it was this glowing light that produces the final image on the film, not the x-rays.

This demonstration is an education tool intended for technologists working with x-rays, medical physicists in training, advanced high-school students, and nerds (I use this term lovingly) interested in science.
