X-ray film is generally coated quite heavily on both sides with a fairly
fast, fairly contrasty blue-sensitive or, sometimes, ortho (blue + green
sensitive) emulsion. These days, the image is formed largely by
fluorescence from phosphors in the film holders (as opposed to directly by
the X-rays), which allows for much smaller X-ray doses. Because of the
thick emulsion on both sides, it has huge amounts of silver in it -- silver
recovery is not optional for X-ray labs. I've never tried using it for alt
work -- I assume getting the back side exposed without the phosphorescence
could be problematic.
