Patrick, microwave ovens emit microwaves (radio waves in the gigahertz frequency), not X-Rays.

I experiment with high voltage as another hobby, and I've taken apart several microwave ovens. One time, I actually powered up the magnetron tube from a microwave...outside of a microwaven oven. I limited the power though. But it lit up a neon tube with no wires, and it put a loud hum on my stereo.
Anyway, that's a whole other topic.
I just found this topic through a group Flickr, by the way. I was asking if anyone had tried using X-Ray films in a camera. Someone in the group gave me a link.
Modern Xray film is used in "cassettes" that have blue, and or green phosphor screens which expose the film with visible light emitted from the screens in contact with the film. The X-rays cause the screens to glow, exposing the film.

As the X-ray film sensitivity gives similar pictorial results to the old Wet-plate collodion (tin type) photos, or in the case of the green sensitive (ortho), similar results to Ortho style camera film.
