IntroductionThe latest version Micro-Detective products build on the ORTEC pedigree ofHPGe nuclide identifiers which began with the introduction of the ORTECDetective in response to the 9-11 aftermath and the realization that it was vitalto provide an effective solution to the problem of potential illicit trafficking ofnuclear materials by terrorists.Since 2004, the ORTEC Detective product line capabilities have broadened inscope and now cover a range from large installed freight monitoring systems,search systems and the light weight Micro-Detective products for in-fieldhand-held operation. All share the same ORTEC HPGe technology andadvanced Detective analysis algorithms.In the latest version Micro-Detective and Micro-Detective-DX instruments,new technology provides an impressive increase in the lifetime of the internalbattery: up to 66% longer or 5 hours typical operation on a single charge. Anew “snap open” battery door allows an exhausted battery to be replaced inseconds and the instrument re-started with a full battery with almost nointerruption to operation. A new generation low-power cryocooler provides “silent running” operationand improved operational lifetime.

A Long and Distinguished Pedigree

ORTEC Detective products are already deployed widely inthe battle against illicit nuclear trafficking. Hundreds arebeing used worldwide by (among others):Departments of Homeland SecurityEmergency Management TeamsDepartments of Defense Civil Support TeamsNational Security Organizations Police DepartmentsBomb Disposal Teams Nuclear Safeguards OrganizationsAirport Security OrganizationsEmergency Response Teams Nuclear Fuel ManufacturersCustoms and Border Control Nuclear ResearchersNavy, Army and Air ForcesUS NNSA second line of defense “Megaports” initiativeInternational Atomic Energy Agency

HardwareThere are two models of Micro-Detective available:• Micro-Detective: Lightweight, Portable HPGe Identifier with Gamma and

Neutron detection.

• Micro-Detective-DX: “Gamma only” version of the Micro-Detective.Both models of the Micro-Detective feature the same compact, light weight andrugged hardware. A 50 mm diameter HPGe crystal in a “hardened” cryostat iscooled by an integrated low-power Stirling-cycle cryocooler. The latest revisionMicro-Detective features a new cooler offering reduced levels of acoustic noiseand vibration, and longer operation life. The hardened cryostat is entirely free ofconventional molecular sieve allowing the instrument to be turned off or on atany point in the detector cool-down or warm-up cycle without risk. This isimpossible with conventional HPGe cryostat systems which require carefultemperature cycling procedures to avoid damage. A built-in digital MCA system and powerful data processor are included. Allmodels feature the same bright and clear VGA resolution display, readable indirect sunlight, with a touch sensitive operator screen. Menu navigation is highlyintuitive. The radionuclide gamma-ray spectrum may be displayed andmanipulated (e.g., vertical scale, zoom) like a conventional multichannelanalyzer. Gamma and neutron count rate and gamma dose rate are displayedcontinuously both numerically and in bar graph form.In the latest version, the Micro-Detective internal battery provides enough powerfor up to 5 hours of operation and is easily replaced in seconds, allowingcontinuous in-field operation. At just under 16 lbs. in weight, the Micro-Detective sets a world record forportable, high resolution nuclide identifiers, by a wide margin.

Analysis CapabilitiesSince initial introduction of the first Detective instruments, identificationperformance capabilities have iteratively been improved through taking part inmany independent performance testing programs. These programs aresponsored by governmental and international organizations, such as the USDTRA, the IAEA, and most recently the on-going international ITRAP-plus 10testing program.Micro-Detective performance has continued to advance as a result of theserigorous test programs. As the needs and best practices of deployingorganizations have also evolved, Detective software features have expanded tomeet these new requirements.

Summary of Operational Features(refer to Technical Specifications for more detail)• Three “Search Modes”:

Gamma/neutron total count rateSNM Search modeSliding average “monitor” mode

• User choice of identification schemes:“Classify Mode” (by nuclide type: “nuclear, natural,medical, industrial, etc.”)“ANSI mode”Time preset or continuous count selectable to matchCONOPS Suspected Nuclides (not in preset mode)More sensitive LCX mode for SNM detection

• Background collect feature eliminates reporting of background nuclides.• “Smart” spectrum stabilizer ensures optimum results, even with hard-to-analyze spectra.• ANSI N42.42 format storage of spectra.

Calibration and StabilizationThe instrument is calibrated prior to shipment from the factory. The energy calibration may be checked and adjusted with any known source witha clean gamma ray between 0 and 3 MeV. A higher energy is recommended. Cs-137 is often used. Calibration can be manual or automatic.Background collection is a required part of calibration. By allowing for activities already in the background, the system will not report nuclidesdetected in the background. The background must be updated on a schedule which is chosen by the privileged user.SMART Stabilizer The “smart stabilizer” stabilizes the gain very precisely on the 1460 keV peak of K-40, if present. If there is no K-40 presentor if Eu-152 is detected, which could interfere with the K-40 peak, the stabilizer setting is held but not adjusted until “normal” conditions return.Even though the Detective is a highly stable instrument, the smart stabilizer allows accurate determination of more complicated mixed spectra.

Optional Software for the Micro-DetectiveThe Micro-Detective is fully supported by the latest versions of the highly successful MAESTRO MCA Emulator as well as ORTEC GammaSpectroscopy Packages such as GammaVision for generalized HPGe spectrum analysis, FRAM and MGAHI for Pu and U isotopic ratioanalysis and ISOPlus for in-situ waste assay analysis. The integral USB connection in the instrument hardware provides full PC control, real-time live MCA display, fast data transfer of single and multiple spectra to the PC, and full ORTEC CONNECTIONS network support. Separatebrochures are available on request. PLEASE NOTE: MAESTRO is supplied as part of packages containing "PKG" in the model number, or itcan be purchased separately at a later date.

The Micro-Detective is a member of the ORTEC CONNECTIONS family. Remote MCA control and individual spectrum download, even over anetwork, is achieved simply, by the use of ORTEC CONNECTIONS products such as MAESTRO MCA Emulation software. Multiple spectra may beblock-transferred from the instrument controller to an external PC by the use of Microsoft ActiveSync. Third party products such SOTI “PocketController Enterprise” may be used to implement the 802.11 wireless feature to provide remote wireless control of the complete instrument.

RADIATION DETECTORSThe Micro-Detective includes three separate radiation detector subsystems:A high resolution high purity germanium (HPGe) detector for nuclideidentification.A compensated GM Tube for dose rate.A moderated neutron detector (absent on DX model).

HPGe Detector P-type high-purity germanium. Coaxial construction.Crystal Nominal Dimensions: 50 mm diameter x 33 mm (±10%) deep.Cryostat/Cooler: “Hardened” cryostat, with high reliability, low-powerStirling Cooler. The cryostat design is such that the Micro-Detective may beswitched off at any time and power subsequently re-applied, without havingto wait for a full thermal cycle (full warm up before cool down), as is normalpractice with a HPGe detector system. This feature greatly increasessystem availability during measurement campaigns.Digital Noise Suppression: LFR Filter.HPGe Cool Down Time: The high reliability cooler is designed forcontinuous operation. Between making measurements the unit is poweredfrom a DC supply, car battery or other high capacity device. Initial cool downtime depends on ambient temperature, but is typically <12 hours at 25°C.Gamma Dose Rate Detector Two detectors determine the gamma doserate over a wide range from <0.05 µSv/h to >10,000 µSv/h, a dose-raterange of around six decades. For low dose rates, below ~20 µSv/h, thedose rate is determined from the Ge detector spectrum. For dose ratesabove this value, the internal compensated GM tube is used. Instrumentswitches between the two automatically.Dose rate uncertainty <(–50% to +100%); continuous audible alarm at doserates >10,000 µSv/h (fixed maximum threshold), user settable thresholdbelow this.Neutron Detector Module (non -DX model only) Single tube: 4" activelength, 0.5" diameter.

Technical Specifications: Instrument Nuclide IDMessages: Classify ModeThe form of the primary ID messages is:

"Found CLASS(#)" or "Suspect CLASS(#)"where “CLASS” is

MedicalIndustrialNORMBremsstrahlungOtherNuclear UraniumNuclear PlutoniumNuclear Neptunium

And "#" is the number of nuclides of that class identified.The table lists the Detective Library v8.5 radionuclides according to theircategories in the “Classify” ID mode.

Classify Mode Message RationaleThe following explains the criteria for selected Classify ID Display Modemessages.HEU (highly enriched uranium): This message is displayed if the majorlines of uranium are detected and the ratios of the intensities of the linesindicates the U-235 content to be above about 70%.Am241 (unshielded) in the “Industrial” category: This message isdisplayed if the 59 keV peak is located. It could mean that an Am-241source such as a smoke detector is present. Move closer to the sourceand/or count longer. This will allow the higher-energy gamma rays toaccumulate in the spectrum, in case plutonium is also present.Unknown Peak and Unknown/Beta Emitter: This indicates the gammacount rate is higher than can be accounted for based on the peaks in thelibrary. The implication is that either an unexpected nuclide or a betaemitter is present (beta emitters typically producing counts over a broadrange of energies). Move closer to the source and count longer todetermine the nature of the suspect item. If another ID is found, then theUnknown Peak or the Unknown/Beta Emitter ID are suppressed.

“Found Nuclide” Screen MessagesRDD Detected: This message is posted when estimated activity is >100mCi, whether the activity is from threat or innocent nuclides. The gammacount-rate and dose-rate meters on the Survey Mode and ID Modescreens display a flashing red background and extremely high count anddose rates.

Gamma-Ray Identification Performance Data for Uranium and Plutonium (Typical values based on data obtained from actual measurements by ORTEC personnel.)Single SourcesUnless otherwise stated, these data were taken at a standard dose rate from the source of 500 nSv/h measured with a calibrated dose rate meter at theinstrument detector face according to ANSI N42.34. When an absorber was present, the dose rate at the detector was measured THROUGH the absorber.

Unshielded and Shielded Uranium: DU, U-NAT, LEU, HEUThe time to identify as uranium, either unshielded or shielded by up to 5 mm steel, is <2.5 sec. For LEU and HEU samples, the type ("LEU" or "HEU") isalso reported in <2.5 sec. LEU and HEU samples shielded by 1.6 mm lead are identified as Uranium in <2.5 sec.Unshielded and Shielded Plutonium: Weapons Grade (WG), Reactor Grade (RG) (~60–93% 239Pu)Time to identify as Pu, unshielded or shielded by up to 5 mm steel or 10 mm lead: <13 seconds for all types of Pu (with Cd filter if high Am content). ForWG Pu the type "WG Pu" is also reported in less than <35 sec.

MixturesIn all cases, the mixture consists of 500 nSv/h of the "mask" nuclide, added to the specified quantity of uranium or plutonium. The "dose ratio threshold" isdefined to be the standard 500 nSv/h dose rate from the mask in ratio to the smallest dose rate from U or Pu detectable in the time stated.

Uranium at 500 nSv/h in the presence of Cs-137 or Co-57 mask (unshielded)Time to identify as uranium <2.5 sec. For LEU and HEU, the type ("LEU" or "HEU") is also reported in <2.5 sec.Uranium Dose ratio threshold for 60 second measurement in the presence of Cs-137 or Co-57 mask (Dose from mask: Dose from uranium)>7:1 for identification as uranium unshielded>3:1 shielded 5 mm steel.>2:1 for reporting as LEU or HEU unshielded>1.5:1 shielded 5 mm steel.Plutonium at 500 nSv/h in the presence of Ba-133 maskTime to identify as Pu <20 sec, unshielded or shielded by 5 mm steel or 10 mm lead.
