AN APPLICATION OF LATENT IMAGE INTENSIFICATION TO FLASH RADIOGRAPHY

摘要

This report describes the technique of post-exposure as a method of intensifying the latent image of shadowgraphs taken with flash radiography. The film is first subjected to a high intensity, submicrosecond exposure for a few minutes. Negatives of improved quality were obtained with the post-exposure technique, consequently the difficulties in radiography caused by shielding and variations in x-ray output are greatly reduced.
