In reply to elevated film based radiography.
Yes conventional RT can be carried out at elevated tempratures, but cooled cassettes must be used to avoid film damage.
Air cooled cassettes have been used very succesfully.
These are made up by sandwiching the film between aluminium sheets, and passing chilled air over the sandwich layers.
Film identification and pich marks are positioned on the front face of the aluminium sheets to avoid direct contact with the piece under examination.

Just a suggestion for your elevated temp X-ray. If geometric unsharpness or object to film distance is not a concern a 1.00" layer of Kayo Wool and strips of corrugated cardboard could do the trick. Use a "J" tube if possible. You will also have to work fast.
