An Irradiation, Transfer, and Counting System for Neutron Activation Analysis of Short-Lived Components in Inhomogeneous Samples

Abstract

A system is described which gives uniform, reproducible irradiation of samples to be analyzed by neutron activation using a 14-MeV neutron generator. The system simultaneously rotates, revolves, and traverses both an unknown and a standard sample past the target of the neutron generator, and then transports the samples at completion of irradiation to a remote counting station where the samples are removed from the irradiation capsules and counted. Data are given to show uniformity of irradiation and precision obtained in the analyses for oxygen in a series of NBS standard reference metal samples. © 1970, American Chemical Society.
