An Investigation into the Effects of Scattered Radiation upon Image Sharpness and Contrast using Cobalt-60Gamma Radiation and Steel Plates in the Thickness Range 20to 100mm,

摘要

The effect of scattered radiation generated in the specimen,on the image of detail on a radiograph,was studied,using Cobalt-60-gamma-rays and steel plates. It is found,contrary to some other published work,that there is no effect on image sharpness,due to the scattered radiation. (Author)
