説明

Contamination of X-ray film is difficult to avoid when the bulk film processing is carried out by an automatic film processor. Developer in the processor frequently becomes discoloured due to oxidization of the primary developing chemical exacerbated by deletion of the sulfite caused by high temperature treatment. The developing rollers also become discoloured and contaminated while functioning in developer discoloured by oxidization. X-ray films become badly contaminated by the interaction of these two factors in the following manner, that is, oxides and silver chloride produced in developer adher to the film surface and dirt on the developing roller transfers to the film surface. We have developed a new developer resistent to discolouration through oxidation, and which also functions to maintain the clarity of radiographic image, and have made many test runs using in the automatic film processor and have had very satisfactory results.
