摘要:

A forward Compton scatter gamma-ray imaging device is briefly described and the gamma-ray absorption in mild-steel samples containing voids is discussed. It is shown that in general any corrections for absorption invariably produces artifacts in the images of regions around voids, although this phenomenon is less significant for smaller voids and less dense materials
