Abstract
Neutron gaging provides an excellent alternative to neutron radiography when it is necessary to determine material density or small differences in thickness. The neutron gage is virtually free of the “noise” inherent in the neutron radiographic process. The problem of variable neutron source intensity when using a nuclear reactor for gaging has been solved by a unique detection system. The system has been used successfully for production analysis of small assemblies on an automated sample changer, and for long explosive cords using a constant speed drive.
Sensitivities have been measured using the neutron gage and neutron radiography under carefully controlled tests. The data are compared to illustrate the results obtainable from the two processes. Comparative results, including destructive test data, are also discussed for an actual production inspection.
