Neutron-Activated Gamma-Emission: Technology Review

Report No. ARL-TR-5871
Authors: Marc Litz, Christopher Waits, and Jennifer Mullins
Date/Pages: January 2012; 48 pages
Abstract: This report describes the technical basis for the technology in place using neutron-activated gamma-backscatter techniques. Commercially available systems are used. The details of the capabilities and differences in these systems can best be compared when the technical details are understood. The choices between types of electronic neutron generators are described. The types of γ-detectors are described and compared. The analysis techniques that produce the results within minutes are compared for accuracy, reliability, statistical validity, and speed of acquisition. The potential for use in three identified concept of operations (CONOPS) are described.
