identiFINDER
The identiFINDER instrument series are user-friendly instruments that identify man-made and natural radionuclides and combines high sensitivity with a wide dose rate range. The instrument has a dual purpose design to facilitate locating missing or offending sources and then identifying the source via its gamma spectrometry and nuclide identification capability. The identiFINDER is a complete digital gamma spectroscopy and dose rate system. It integrates multi-channel analyzer, amplifier, high voltage power supply, and memory with an integral scintillation and GM detector. The identiFINDER is ideally suited for homeland security, industrial, medical, nuclear power generation and nuclear fuel cycle applications.

| Stabilization | In the non-Ultra models, a built-in 137Cs reference source (<15 nCi/500 Bq) is used for online stabilization and in-situ calibration without user interaction. With either stabilization method this special identiFINDER feature allows operation over temperatures between -20°C and +55°C (-4°F and +122°F). The Ultra provides the user with the benefits of LED stabilization technology with or without a small 3nCi Cs137 source, as preferred for implementation and transportation |
|---|---|
| Software | The identiFINDER provides for easy storage of up to 100 spectra and rapid transfer to a PC for reach-back and/or qualitative in-situ analysis with the software supplied. |
| User Selectable Nuclide Library | There are 74 reference spectra of radionuclides stored in six libraries: Nuclear, Industrial, Medical, U.S. Customs Service, OSI (On Site Inspection by IAEA officials), and Security. All sub-libraries except OSI can be edited by adding or deleting specific nuclides from the list. Ten reference spectra can be measured by the user and added to the predefined library spectra. Identification is done by a template-matching correlation procedure. |
