title: Construction issues surrounding a portable four-band neutron detection system.
abstract: Solid state-based surface barrier detectors (SBDs) have been employed in neutron radiation dosimetry for over half a century, each combination of detector featuring positives and pitfalls. Here the implications of constructing a portable neutron spectrometer device, based upon moderating high-density polyethylene substrates and utilising different types of large-area solid state SBDs, are discussed.
