Hi! I have some 30x40cm photo paper for radiographs. I made 6 already, 4 sheets left and I'm going to use it tonight.
Hand on PC keyboard - OK
LEGO racing car - too short exposure and not center
Shells - OK except the white corner. It looks realy cool so i'm going to x-ray it again just for a copy
Motherboard - too low energy/too short exposure and white corner
Motherboard again - good energy and exposure time, but i placed it in wrong corner of the x-ray cassette
headphones with mp3 player - a bit too short exposure time
So i'm going to x-ray LEGO car and shells again, maybe motherboard too. Two sheets of photo paper left and no ideas, please help me I't should be something suitable to put the radiograph in frame and hang on wall
And by the way. I tried also to exposure x-ray film without cassette to get sharp image, but it needs REALY long exposure. I placed the film 10cm under x-ray tube for about one minute and after developing i was hardly able to notice that it was exposured at all! B/w photo paper in blue cassette needs only 5s in 50cm distance from the tube to get completely black.

Those are really niceI like the keyboard one! I`m going to have to do one of those myself to match the mouse x-ray!
I tried taking radiographs with raw paper too, but the exposure times are horrendous, and its hard on the tubes. Heres a good one for you though, get hold of one of those instant polaroid cameras, and cover the lens with black tape. Pick an object roughly the size of the polaroid film (4x4 inches).
Set up your x-ray machine ready to take an x-ray. Now very quickly, depress the shutter on the camera, and the instant the unexposed film emerges, get it under the x-ray tube, with the object on top, as quickly as possible, and switch on the x-ray tube.
The film is still sensitive to x-rays, WHILE it is still developing. Reciprocity failure of the film produces a wonderful variation in colour of the developed image. I have had them turn out yellow, sepia, pink, and blue, depending on the exposure time.

Huge tubes usually become a real artwork!
But sometimes Kirlian photos or Lichtenberg figures can be better, i have this photo in a frame on the wall
Ciao! Fabio.
********************* EDIT *********************
Both images was taken on lithographic film, developed and copied on paper, for the coin the enlarger was used, for the valves no enlarger is necessary, just a glass sheet and a lamp
I use "MACO Genius film" as litho film because it have a really fine grain, is easily obtainable and isn't so expensive (about 15€ for five 24x30cm sheets)
