Abstract
The major radiation spectrometer utilized by DREO for the measurement of both free-field and in-vehicle field has been until recently the NE213 liquid scintillator. In the area of neutron spectroscopy the poor energy resolution and relatively high lower energy threshold are this spectrometer's major drawbacks. With a view to circumventing these problems, DREO recently decided to augment its neutron spectroscopy system with a 3He-based ionization chamber. The report describes the advantages of this detector and outlines the methodology used to generate the energy-dependent response matrix necessary for spectral unfolding. Finally, the unfolded spectra from various radiation sources are presented and compared with theory and other experimental results.
