摘要：

Low-cost radiation detectors capable of providing efficient gamma-ray and neutron detection are essential in passive nuclear monitoring systems such as radiation portal monitors (RPMs) and detection of Special Nuclear Materials (SNM) through Active Interrogation (AI). Three low-cost detector solutions are discussed in this paper-(1) Large-area polystyrene-based plastic scintillators for AI (2) Pulse Shape Discrimination (PSD) capable plastic scintillators doped with heavy-metals for imparting gamma-ray spectroscopy (3) Composite detector technology based on inorganic scintillator submerged into the plastic scintillator, for detection of thermal and fast neutrons in addition to gamma-ray spectroscopy. Composite detectors using inorganic component such as Cs2LiYCl6 (CLYC), Cs2LiLaBrxCl6-x (CLLBC), or CsI:Tl have been developed up to 4 '' sizes. Neutron and gamma efficiencies are compared for samples with different inorganic loading.
