General Description
The Guardian Predator, Generation 4.3, backpack is built for military, first responder and law enforcement search applications. It is a human portable instrument primarily used for field search missions over a large area. Detects gamma rays, neutrons, alpha and beta particles. Gamma ray information includes isotope identification. Instrument displays exposure rate as well. Data is collected within the system on board computer and correlated to time and GPS positions. Transmission of data is performed one of two ways, either 802.11 wireless or Ethernet cable.
Technical Description
The Guardian Predator, Generation 4.3spectroscopic backpack includes: a neutron detection unit (lithium-6), a gross counting gamma detector (PVT), one (1) spectroscopy grade detector (NaI(Tl)), one GM Tube, one alpha/beta detector, an operator display interface (ODI), 802.11 radio, and a GPS. The system is comprised of the following: data analysis, alarm and reporting of neutron and gamma ray detection as well as the ability to perform gamma spectroscopy with 1024 channels and provides nuclide identification using a library of standards. The system is supplied with data logging, all required electronics, cables, batteries (greater than 8 hours operation, rechargeable), and transport case. This system is a full featured gamma/neutron measurement system for wide-area searches.
