NeuPortTM and NeuTruckTM solutions provide a cost effective plug-and-play replacement to He-3 for portal and vehicle mounted monitors. These are 6LiF/ZnS(Ag) based flat packaged neutron sensitive detectors contained in high density polyethylene moderator enclosure. Neutrons are captured by the 6Li and the reaction products excite emission from the ZnS(Ag) scintillator which in turn is absorbed in an adjacent ribbon of wavelength shifting fiber.
Proprietary Pulse Shape Discrimination (PSD) algorithm is employed to count neutrons and reject gamma ray events.
Note: Neutron efficiency is measured with 252Cf moderated source @ 2 meters from the center
