x- ray film stock

I am considering trying out the x-ray film stock for architectural photography. Using it in a normal camera the result will not appear like a x-ray images seen a in a hospital but the idea of using this kind of filem still adds a notion of transparency to my project. I am going to photograph some of the buildings that used to be cinemas and I think x-ray film would be suitable.

I am still not sure of how these negs will be enlarged but I have been reading about someone using the Pyrocat HD developer and I found some here. I also read about the D76 developer. 

I found it a bit funny to realise that the x-ray film is made from old bones (gelatine).. It is interesting that old boned is used to keep other boned healthy.
