Explosives detection via fast neutron transmission spectroscopy

Material Analysis Using Characteristic Gamma Rays Induced by Neutrons

“…The National Academy report (NNMAB-482-6, 1999), written in 1999, was extremely critical of the utilization of PFTNS for airport security. However, Overley suggests that detection rates of 93% and false alarm rates of 4% are possible with this technique (Overley et al, 2006).…”

Potential and status in imaging with fast neutrons

“…These unique properties of fast neutrons were exploited for various applications, foremost in civil security, like the detection of explosives and drugs in luggage and freight [1][2][3][4][5]. In [1] pulsed mono-energetic and collimated neutron beams from an accelerator are used for neutron induced gamma analysis of containers.…”

A method for using neutron elastic scatter to create a variable energy neutron beam from a nearly monoenergetic neutron source

“…The search for explosives and narcotics can be performed using Pulsed Fast Neutron Analysis (PFNA) and neutron elastic scattering (Buffler, 2004;Lehnert et al, 2012;Lehnert and Kearfott, 2010, 2011a, 2011bStrellis et al, 2009;Whetstone and Kearfott, 2014). Neutron transmission and fast neutron radiography, which utilize neutrons that do not interact in a target, can be employed to investigate the elemental composition of a target (Overley et al, 2006;Sowerby and Tickner, 2007).…”
