Paper Abstract

We present measured data on the neutron detection response of the GammaTracker handheld radioisotope identifier. Two neutron detection modes are discussed: measuring absorption gamma rays from the cadmium present in the Cd-Zn- Te spectrometers, and measuring the absorption gamma rays from moderator material present in the environment. In both cases, the capture gamma rays can be imaged to help locate a shielded neutron source. In this work, we discuss the total neutron detection efficiency of the GammaTracker instrument, and we present measured images of shielded neutron sources. Prospects for gamma-ray rejection are discussed.
