General
We employ all manner of scientific and engineering techniques in our mission to inspect and characterize materials from low-Z (e.g., hydrogen) to high-Z (e.g., uranium), and low-density (mg/cm3) to high-density (20 g/cm3). The goal is often to gain an understanding of the elemental composition of the object in addition to imaging it for flaws. The attached charts show how NDE or NDC can be performed with multiple modalities (electromagnetic, acoustic, and particles) and can require many technologies and disciplines. We use them all at NCI.
