Ruggedized, Ultra-High-Sensitivity, Transportable HPGe Radionuclide Identification System “No other radiation instrument has more standoff nuclide identification performance in a small rugged package.

• Greatly increased sensitivity, (3x more sensitive than Detective and Micro-Detective models). • Much faster to identify. • More rugged, compact, IP67 standard stackable package. • “Gold Standard” identification performance. • Detective-Remote™ software package; easy integration of multiple Detective-200s into highly sensitive systems, for use in a variety of security situations: • On the ocean (maritime interdiction at sea) • On land (vehicle mounted search) • In the air (aerial search) • Static applications on highways, public events, incident triage • The high flexibility of the many...

Detective-200 in Maritime applications • “Slow Pass” Materials interdiction Detective-200 is very well suited for mounting on naval vessels. The IP67 packaging is immune to salt spray. The tough fold-flat handles make it easy to lift and mount aboard a vessel, or transport from vessel to vessel. A ship-borne Detective-200 system consisting of one or more instruments, controlled through wired or wireless networking via Detective-Remote, is capable of reliably detecting illicit materials on a nearby vessel in a slow “sail by” measurement. Figure 1 shows an example of sensitivity for...

Standoff Detection Detective-Remote Software Standoff detection is the problem of correctly identifying a distant stationary or near stationary radioactive source. The standoff detection limit is essentially a question of signal-to-noise ratio in the detection system. As distance increases, gamma rays are attenuated by air and a fixed field of view means at further distances more background is in the field of view of the source. Both of these affects reduce the signal-to-noise ratio. As with other applications in low resolution systems, background variation is problematic. The high...

Since the first model was introduced in 2004, all ORTEC Detective identifiers have incorporated the same principle technologies and features, namely: • High-resolution, high-purity germanium (HPGe) detector. • Mechanically cooled by miniature Stirling-cycle refrigerator. • Internal high range GM tube provides gamma dose rate. • Fast, Simple and ULTRA-Reliable Classification of NORM, Medical, Industrial, SNM and Natural Isotopes, shielded and unshielded. • Touch Screen or Remote Software Operation. • ANSI N42.34 and ANSI N42.42 compliant. • Battery/AC/DC powered, highly stable digital...

GPS Position Information: An internal GPS receiver displays GPS coordinates which may be saved along with spectrum data for future use. Storage of Data (spectrum, search data, ID results): To internal RAM and removable SD card. Computer Interfacing: USB connection to laptop. Spectral transfer by Microsoft® ActiveSync. Remote control via Microsoft “remotedsp.exe” (supplied). WiFi (802.11) communication. Wireless Mobile MCB Server software. ANSI Mode: This mode is similar to classify mode, but dispenses with the classification, and presents nuclide names directly, both suspect and found. Mode...

Classify Mode Messages The following explains the criteria for selected Classify ID Display Mode messages. HEU (highly enriched uranium): This message is displayed if the major lines of uranium are detected and the ratios of the intensities of the lines indicates the U-235 content to be above about 70%. Am241 (unshielded) in the “Industrial” category: This message is displayed if the 59 keV peak is located. It could mean that an Am-241 source such as a smoke detector is present. Move closer to the source and/or count longer. This will allow the higher-energy gamma rays to accumulate in the...

ANSI Mode Messages The table is divided according to the threat category used to determine ID background color in Monitor Mode and on the Found and Suspect Nuclide reports, e.g., green for innocent IDs, yellow for LCX-mode suspects, and red for threats. NB: if desired and under password protection, the color coding, and therefore the threat classification can be disabled.

Detective-200 Detailed Specifications Summary OPERATION MODES SEARCH Scanning mode for location of radioactive sources. Speed settings 0.1 to 50 seconds/point. SNM Search Mode™ Nuclide-specific search mode for U-235, Pu-239 and neutron counts. Ba-133 surrogate detection may be turned on for training purposes. Bar graph display of nuclide confidence level. Aid to Identify mode. MONITOR Mode The instrument collects one spectrum per second and runs the ID algorithm against an 8 second sliding average. This mode is more sensitive to sources which move relative to the instrument. LCX “Low...

Search Mode (Gamma/Neutron) Dwell times 0.1-50 seconds per point. Over-range warning. SNM Search Mode™ Nuclide-specific search mode for U-235 and Pu-239. Bar graph display of nuclide confidence level. Identify Nuclide ID and classification. "Intense" shows the most intense lines list, which is a continuously updating list of the 12 best peaks currently detected. The nuclides and energies are based on the internal nuclide library. The rank is based on the confidence value for the peak. "Save" Saves the spectrum. Format choices: ORTEC “.CHN”, ORTEC “.SPC” and ANSI N42.42. "Display" brings up...
