AN EVALUATION OF COLOR RADIOGRAPHY FOR INDUSTRIAL USE: THE RE-EXPOSURE METHOD.

Abstract : Although no color film is specifically manufactured for radiographic purposes, attempts have been made to produce color radiographs by modigying the producer's suggested film development procedure. Step wedges of aluminum steel, zirconium, and uranium were radiographed and the film developing process was modified according to procedures established at Argonne National Laboratories. The results, using a positive and negative type film, and a detailed record of the procedures are presented. The results indicate that color radiographs are difficult to produce, and the process time-consuming and expensive. Areas of possible future investigations are suggested. (Author)
