An Automated Nondestructive Testing Gauge of the Radius Density Distribution of High Explosive Cylinders by Gamma-Ray Penetration

摘要

An automated nondestructive testing gauge of the radius density distribution of high explosive cylinders by gamma-ray penetration is briefly introduced in this paper summary. The gauge is especially emphasized on the excellent counting stability and the automated full-process control. The gauge can achieve a density resolution as small as 0.1% at a 95% confidence limit.
