Advanced Gamma Nondestructive Assay

Learn about gamma ray based nondestructive assay concepts applied to nuclear nonproliferation needs.


PU Gamma Ray Spectrum


This training course presents a wide range of gamma-ray measurement techniques used domestically, within the DOE complex, and globally by the IAEA and, other International nuclear regulatory agencies. 

The uses for the gamma-ray measurement techniques covered in this course include:

  • Material safeguards
  • Criticality safety
  • Material identification
  • Nuclear security

The course is composed of lectures that describe underlying theories followed by hands-on laboratory exercises covering measurement techniques.
