Radiation Sensors

OWL is a contextual system that can be coupled with a suite of other detectors to provide actionable intelligence and enhanced situational awareness. The system integrates visible and thermal cameras with PSI’s powerful onboard machine vision and keypoint tracking algorithms. OWL can also operate as a standalone, advanced camera system.
MURS is an advanced mobile radiation detection, identification and source localization system coupled with day/night contextual imaging and inertial navigation subsystems discreetly installed in a 4x4 vehicle. The standard MURS includes a Chevrolet Tahoe SSV and is complete with a low-profile law enforcement package.
PERM-Mobile is an advanced radiation detection and source identification system that can be easily configured for mobile and static applications. The system provides fast vehicle integration with power provided through the 12V vehicle supply. The PERM-Mobile uses a local WiFi network and a tablet which provides the user interface and processes the detection algorithms.
The PERM gamma detector provides gamma detection and isotope identification. It uses a low-cost 2 in x 4 in x 16 in NaI(Tl) crystal, enclosed in an IP67-rated housing, as the scintillation material. The crystal/photomultiplier tube (PMT) package is a commercial item supplied by St. Gobain. The design associated with the packaging of the COTS scintillator is driven by the need to provide medium-resolution (~8%) gamma spectra (30 – 3000 keV) with accurate and stable energy calibration.
