Abstract

A study of the major factors which affect the NaI crystal background in the presence of neutron sources in the region of 10.8 MeV (energy of the neutron capture gamma-rays from nitrogen) by neutron capture gamma analysis is described. The neutron flux is provided by two collimated 370 GBq (10 Ci) Pu−Be sources. Results indicate that there are two major factors affecting the background in the 10.8 MeV region, namely random coincidence counting (contributing about 65%) and Gaussian Spreading (contributing about 25%).
