Radiographic Tests on XF4U-1 Engine Mount, SAE 4340 Steel

Abstract

Prolonged contact between radiographic film and metallic intensifying screens often leads to blackened areas in the developed film. The effect is more noticeable the higher the speed of the film and seems to be due to the presence of moisture in the air rather than to the particular metal used as a screen. The use of paper or other organic spacing sheets between the foil and the film was found useless under conditions of high humidity and temperature and quite unnecessary when the film holder is kept moisture free by simple means described herein.
