Faster, less expensive and thorough results -- When we wanted to identify material or check the quality of material in the past, we either had to do a chemical analysis of the material, which is a very slow process, or we had to do a sample destructive analysis of the material quality (destroy the material), which was very expensive. For example, In determining whether a casting is whole and there are no occlusions (holes) within it, or at least there are only small numbers, castings had to be sampled and cut open. All you could find out was whether the casting you had just destroyed was okay or not. It was an act of faith to say that the other castings were okay. Sampling is a little better than an act of faith if the process that produced the castings was carefully controlled, of course. Then you have a better chance that a sample is representative of the rest. However, these methods of testing materials or quality were always batch processes. They were not continuous. Today, thanks to nuclear science and technology we can analyze materials thoroughly and continuously, with less expenses and much faster.
