Abstract

Segmented Gamma Scanner (SGS) is a commonly used nondestructive testing (Non-Destructive Assay NDA) method. SGS uses radial rotation, axial segmentation, segmented scanning of the non-uniform sample of the \homogenization", making it possible to accurately measure the radioactivity on each segment and is currently widely used in the field of arms control. This paper introduces a self-designed SGS measuring device and uses this device to perform a large number of subscanning experiments on different measurement objects in the laboratory. It also studied the detection performance, stability and SGS method of different objects the accuracy of the measurement results.
